A clip-on is effectively only one turn onto the core. The inductance increases as the square of the number of turns on a core, so, passing the wire around again is 2 turns which will give you 4x the inductance of the straight clip-on.
I'm going have to see if this might help with the 3.5mm I have in my car to phone ..when I leave the radio on (on aux) even if I don't have my phone attached, and turn the car off..I get a loud pop
My issue is a constant, extremely high pitched tone that is audible whether or not there is any other signal being sent to these old Pioneer 77 speakers, from a Pyle surround sound speaker amp
Ouch. I had that before with a car stereo head unit, and it drove me bonkers because it was audible in everything it played back! Super-disclaimer: I'm not a sound engineer! :D But that said, these kinds of things can have multiple causes, from EMF (which is where the cores come in) to a bad ground (where you can either try another outlet or try using a power conditioner) to bad capacitors that give off noise (which leaves you with 'repair or replace'). I hope you're able to solve the problem though. My car stereo, I'd tried cores and extra grounding wires and ultimately had to replace the unit. If the amp is relatively new, there may be a warranty for those kinds of issues or an easy repair option.
I bought these new logitech usb computer speakers and I hear this high pitch noise coming out of them especially when I'm not playing anything, I think the problem is with the grounding. Will this ferrite core help with this issue?
It can help, yes. If you can try putting a core on the speakers at the USB cord where that plugs into the computer, that might be your best bet if the noise is coming from a bad ground on the PC. I say that assuming it's just a USB connection to the computer. If it's also needing you to plug in an audio cable (say, to the stereo jack on the back of the computer), then a core on that cord would also be a good idea to try. Good luck! I hope this helps.
I installed a Holley Sniper EFI & the EMF fields from my vehicle 12v system are causing it to run & stall intermittently. I've wrapped wires & added ferrite clip to wire my meter showed high. Still problems, any ideas.
I haven't run across that, but I *did* run across this on Holley's forums - it's a link advising to keep an eye on how you run the EFI's wires and also that higher-grade spark plug wires will have more shielding. It's been a long time since I owned a vehicle with a Holley, so I hope this helps you! forums.holley.com/showthread.php?50168-EMI-RFI-Problem#:~:text=Yes%2C%20all%20wires%20coming%20out%20of%20the%20Sniper,super%20careful%20with%20all%20of%20the%20Sniper%20cables.
Make sure ALL your grounds are good. Block, chassis, battery, make sure they all are low resistance. Some Aftermarket ECU companies like Fueltech suggest to ground the ECU directly to the batter, as the battery itself actually acts as a filter for noise ect. Hope that helps somebody
@@satyavratadas1640 Hello, what can cause the speed of voltage drops in car audio system? No connection loss in AUDIO wires (it is possible that somewhere in the original installation of car) Under the hood i cleaned all ground wires, alternator is okay, but i still have weird issues, like SHort circuit but induction between power wires. Sometimes i cant charge my amplifier with bulp 5w, sometimes charging amp is only 6 sec, sometimes voltage stop at 5volts and comes down and up (4,5-5,3v) and cant charge! Lol. Its on all tested amps, like induction in wires. I have too bad sound, capacitorrs degradation itp.
Thanks for posting this. I just purchased a sound system that came with one of these for my rear speakers and I didn’t know what it was for. The manual only mentioned them it as optional without explanation.
That's a good question! I know it won't hurt, since the primary benefit is filtering out higher frequency. It can't hurt to try, I'd love to hear if you find a difference. It's mostly designed to solve an RF interference problem though.
You certainly could! I originally did this video to help out a friend to understand the basics of what Ferrite cores are and how to clip one onto their mic to solve an interference problem--but yes, while putting a Ferrite Core on can be a simple test and provide a quick fix, introducing multiple turns of copper around the lead is certainly another option. Thanks for sharing this! :)
Hi Techmania! It is useful for either. A subwoofer is a very big speaker, so it will work for either. The use is to remove any RF interference that--for a speaker--might cause noise in the speaker. I hope this helps you!
I sometimes get a static sound coming out of my studio monitors when i listen to music, RUclips, make music(anything with audio) Would getting this fix it?
It might! I'll share what I just said to someone else with a similar problem: The noise might be interference from a phone or other wireless device that a ferrite core might not be able to mitigate. I would put the core as close to each speaker as possible (one on each speaker cable). Check out this video and see if any one of these is the sound you're running across - ruclips.net/video/uPYyrS7fc7g/видео.htmlsi=mY6SDCu9P32Jik5N - if so, it's a matter of having to keep the phone or other wireless device further away from the speakers to avoid this interference. Older speakers can be less well shielded than newer ones, but this is why I don't bring my phone into my studio when recording--sometimes my newer studio monitors pick up the buzz too. I hope this helps you! Sorry I don't always get to these comments right away.
I’m getting RF interference on a FM stereo I’ve tried a lot of things but have had no luck removing it. The transmitter has two chokes on the coax, one at the antenna and one close to the radio. The coax is wound on a a piece of PVC pipe on the mast 6” down from the antenna. I used 11ft of coax on the PVC pipe. An amateur radio operator gave me this information and said it would work. The stereo is not a new one and uses a “T” type antenna. Can you please suggest a cure. Thank you for your help.
Does it work with smartphones interfering with speakers? I'm using 2 ferrite cores, I've tried placing them on the speaker cables, power cables, close to the speaker itself, close to where the speaker plugs in, and pretty much any variation of that, but I still get the crackling noise if my phone is close to the speakers (50cm). I am using some old speakers (Trust Soundforce 1200), but should that matter?
Hi dakterdee! The noise might be interference from the phone itself that a ferrite core might not be able to mitigate (it sounds like you've tried everything I'd try!).

It works for equipment that's generating noise, like a speaker or microphone. If you did have some sort of setup that was capturing video and there was interference causing noise, it might work for that. Not sure what your specific setup is, but basically anything that might be getting EMF interference from nearby and has a wire sending a signal. Hope this helps!
@ definitely did I took a chance and got a decent amount off Amazon I added them to my lg c3 power cord and all my hdmis apply tv Xbox and sound bar with a subwoofer wireless and 2 reach speakers connected because I noticed my lgc3 was getting more visible film grain and noise and almost static on the picture so added them and even to the power cord because I have at least 9 cables running to one power surge in my wall which is all that I just stated above and it definitely did help ALOT but still some noise and artifacts which I’m sure is from the films streaming in general but they definitely do help a tone and this video definitely helps me with that choice of taken the chance so thank you!🙏

Hi I have a humming problem from my turntable in my hi fi set up. Probably a grounding loop. But I can't seem to fix it . I have separated the power cables from the phono/ RCA cables . Do you think fitting some on the turntable power cable. Or on the rca cable . Your thoughts would help on this matter I'm sure. Thanks Gerald
Hi Gerald! I don't always reply fast, but I hope this is still useful to you. Yeah ground noises in audio are a pain to troubleshoot! But yes, trying a core on the power cable is one way, as is trying the RCA cable. If it's not a pain to move around, plugging into another wall outlet on another circuit is another way to test. You can buy third-party ground-loop isolators like the Hum-X, but the success is hit and miss because it depends on whether the ground problem is at the wall versus somewhere else in the chain. I hope this helps you!
I've been getting interference on speakers in the hall whenever the HDMI cables are running. Hopefully I'll be able to put a few of these on around the place and solve the issue.
What benefit(s) would be achieved if ferrite cores were added to my marine/boat Humminbird/Garmin electronics...GPS w/down-vision, side Imagining and sonar?
Hi John! Most manufacturers use the right quality cables for electronics and some go an additional step and put one of these on their cables at one or both ends, so you shouldn't need one. You wouldn't really benefit from adding one unless you're experiencing a problem with interference and then you want to troubleshoot whether it's a grounding problem or a problem with signals coming through the air around you fouling up your equipment. Usually that sort of problem comes from nearby electronics or being close to a radio tower, etc. It's unlikely you'd be experiencing that in your scenario with side and sonar as the emitters are aimed away from your boat and the equipment (especially the Hummingbird and Garmin brands) should be assembled in good quality and go through Quality Control (QC) checks before it gets boxed up and sent to the store. That said, this is a really good article to explain it a bit more in detail - www.rfpage.com/electromagnetic-interference-and-compatibility-in-radio-frequency/ - the bit about "Radiated EMI" is the problem a ferrite core tries to solve, and in the section "How to avoid electromagnetic interference", the passage about "filtering" refers to devices like a ferrite core. The English isn't perfect in this article, but I like the bits about "How [is] EMI Generated?" and "Sources [of] EM Radiation". Hope this helps you! :)

@@JCASTELLUCCIOJR Rats! I was hoping that would help you, but you might have to try multiple ferrite cores to see if you can kill the interference. Hope you can find a solution, I know how maddening it can be sometimes when things that shouldn't be going wrong, are going wrong weirdly. :-/
So my microphone picks up some sort of radio frequency that comes from the outside, its this trucker that I assume is just using this really powerful radio. I can hear him talking sometimes through my microphone, and I was wondering if putting a ferrite core(s) on the XLR cable would help or not, I already have a star quad cable and I still pick up the frequency, although the frequency stops when I wrap my hand around the microphone end of the cable? It might be that the end that connects to the microphone might not be properly grounded? Or the cable in general isn't properly grounded, I don't know. I ordered a cloudlifter CL-1 recently and I hope that this can somehow clean up the frequency, but if so I don't know. I don't have access to properly grounded plugs in my home, I think it might be that, and if so I don't know what to do :/
This would definitely be a case where you're getting RF Interference, so yes: I'd try putting one on the XLR cable at the end where it plugs into your interface (pre-amp, cloud lifter, etc.). The Cloud Lifter is good for gain staging, so it might help if you're using a Dynamic or Ribbon mic (I'm told it won't work for Condenser mics). One other thing I read was to make sure the XLR cable isn't touching or laying across any power cables. There's also a forum I found where both ferrite cores and hum eliminators were used to solve the problem of CB Radio coming in over the wire - I hope this helps you! homerecording.com/bbs/threads/picking-up-radio-frequencies-whyyyyyy.14830/
Hi adhmekathrada! So many comments I sometimes don't catch 'em all right away--sorry! But yes, if you're getting signal interference, it *might* help, and you'd have to try it in a couple of spots. I'd start by putting one close to where the camera plugs into the recorder or monitor, then if that didn't help try it on the power cord close to where it goes into your setup. I hope this helps you!
Can you use these to reduce noise in a chain of effects for guitar? Where would you use them - audio guitar cable between effects pedals and/or power supply cables? I know guitar pickups also pull in noise, specially single coil pickups. I am just trying to reduce as much noise? Or are these not needed if the guitar/patch cables are shielded?
You're right that good shielding is supposed to solve this problem and you shouldn't need it. If you're getting noticeable noise, that's another story, and that could be a bad grounding or EMF. I'm not a sound engineer like some of the people I know, but if I can ask one of them for more detail, I'll share it with you. As far as using a ferrite core to reduce noise in a chain of effects, you could try connecting it at various points in the chain to see if the noise goes away at any particular point in the chain. Hope this helps you!
@@trentonbennettVO Thank you very much for the ideas. I'll try those. Although, I came across some sound guy on youtube this morning that said he's against cores on audio cables because it increases impedance on an already low signal. But I think like you said I should try at different points. There's no hurt in trying. It's not like something is going to arc!!! Thank you again for your suggestions and for your channel.
@@t2dev I can see the sound guy's point, yeah, if that's a line-level feed it is a low signal. I do tell folks I'm not an engineer--I know several now, but that's outside my range :) I'm really glad this was helpful to you - thanks very much for letting me know how it's been going!

Hi Artin! I did some reading specific to ADSL lines and the answer appears to be, "not really." The only situation in which it *might* help would be if you put one on the power line to the ADSL modem, and that is if the power is the source of RF noise--I'd place it on the end of the cable that plugs into the modem and not the end of the cable that plugs into the power outlet in the wall. Even then, there was some debate as to whether RF could be a problem for an ADSL signal because the ADSL signal flows in a "differential mode" (current flows in opposite directions in each conductor inside the wire, resulting in a net magnetic field of zero). IF your ADSL line also happens to be your phone line AND you're hearing interference when you talk on the phone, THEN it *might* be something you could use to reduce noise on the phone line. So the bad news is, you likely wouldn't get any improvement specific to the ADSL by placing a core on the data cable. The good news is, these cores are a very cheap way to troubleshoot, and on the power cord, they might help reduce or remove any problem related to RF generated by the ADSL modem. I hope this helps you!
I have a 90's lexus with a tape player. Going to try this for my car tape adapter to aux, that I attached to my iphone. Always gives me fuzz on the audio. I could get a bluetooth car tape adapter, but the volume is much louder on the old-school tape adapter 3.5mm aux audio to iphone.
Hey, if you can, let me know if that worked. Ah, nostalgia - me with my tape adapter and my Discman that skipped any time you hit a bump. Clever to use that as a hack for your phone since it's just a standard aux jack. I wonder if the volume on the old-school adapter is louder because it's expecting a line-level signal and it's getting amplified audio? See if the quality is still good if you turn the phone's volume lower and let your car's head unit handle the volume. You might find a sweet spot of great sound!
I haven't been able to find something like that, but if you don't mind a deep dive, this PDF explains with visual charts how the effect works: audiosystemsgroup.com/SAC0305Ferrites.pdf

I have cruise control by Rostra company on my truck 2011 ranger I-4. Keep disconnect itself so I test turn air conditioner on and off affect cruise control disconnect CC itself. My truck battery is old make alternator make very light charge the battery. Do I need add ferrite power cord 12v to CC ? Help to reduced static electricity charge to CC ??
I'm honestly not sure on this one! I've had mechanics tell me sometimes an engine component isn't correctly grounded, but you also mention the battery is old, and in the last 15 years or so I've experienced that once a battery starts to go, it just doesn't put up with being recharged for very long. I'm not sure which of Rostra's products you have and what that configuration is (like is this a speed limiter on a company vehicle?) but I'd probably start by reaching out to them. This link can let you specify exactly which product you need help with: www.rostra.com/support/
Do these eliminate radio frequency noise? I'm trying to remove an entire radio station that's coming through my speakers in my home studio. I've bought a power conditioner, I just ordered these ferrite rings... it's not working. Any suggestions?
H, I attached a Rodin coil (without a ferrite choke ) like the Qi coil on my sound to frequency converter which is connected to my Rockville blutube amp (70 watts per channel) and for unknown reason to me that channel stopped working. It’s possible that when I unhook one of the connections of the Rodin coil the sudden collapse of magnetic field traveled throug the wires and damaged my equipment? Is this possible?
Ergh...maybe? You're definitely far afield of my wheelhouse, but from what I can tell, since a Qi coil *generates* an electromagnetic field, it sounds like that might run counter to trying to handle an electromagnetic interference problem. I would reach out to Rockville and ask them this question if you haven't already. I'm definitely not an electrical engineer with a deep understanding of Qi and Rodin coils. If you haven't tried this already, one thing you might try is to unplug the amp, disconnect everything from it, then do a power drain (you hold down the power-on switch for about a minute to make 100% sure any residual charge within the circuitry is expended). Then connect something simple, plug it back in, and try to run sound without any coils or other modifications. Jeez, I hope you are able to get the problem solved!
Hi jonnystevens9589! It's a good question, but hard to qualify. If there's something faulty about the cable and you can't fix or replace it, then, it's not necessarily a number so much as a question of "what's happening" and "where should I try this?" For example, let's pretend this is a simple pair of speakers connected to a turntable and you're hearing noise. You could put a core on each speaker close to the speaker and if that didn't work, then instead put one on the electrical cord close to where it goes into the turntable. Unfortunately, since this is a "possible" simple fix, and there's more than one cause of the problem, it could ultimately be some other issue like a bad ground or coil whine inside the thing, etc. and more of 'em doesn't really do much to help. I hope this does help you.
Glad to hear this helped you! It's the simplest solution - and yeah, you had to do that fun legwork of trying to nail down which one it was. Congrats on solving the problem! :)
@@trentonbennettVO Yea just scattergun blast solution, hit everything until it stops, got it to quiet down even more after I dealt with a cheap knock off laptop power adapter as well.
It's not really possible to put 'too many' on, no, but if one at the end going into the receiver or one at each end of the cable should tell you whether RF is the problem. Hope this helps you!
No but I have one that is on my usb streamer cable and I have one that is on the power supply for the streamer and the amplifier. I am thinking of the speaker cables because I have a few more leftover.
Would these help with a buzzing sound I am getting from a DRL light strip I have in my bumper of my van? I installed a new head unit and now I am getting a buzzing noise from the light's?
We just had our bathroom remodeled , in the tub is an led light exhaust fan combo. Its creating a raspy buzz on my am radio from 1200khz to 1600khz. Is there anything i can do? even when its off, if you hold up a radio to it, its really a loud raspy buzz. driving me crazy. the buzz is all through the house...but it goes away in certain locations.
They could, though that may also be a grounding (earthing) issue. You can of course put a core on the two connectors, I would also check that I've got the earthing correctly connected and I'd also see if I could plug the turntable into a surge protector (or if you have done so, try a different surge protector or a different outlet). I hope this helps you!
I have a TV in my living room and I run a cb in my man cave and I am getting feed back noise from the TV wen she turns it off and on will this help me get rid of it
It's certainly worth a try. If the TV is getting an over-the-air signal that might be one reason why the interference (as in, you have a digital antenna in your home and maybe that's why there's as much interference as there is). Usually most TVs are well shielded on the inside and tend to operate over wireless as 'WiFi' instead of the traditional over-the-air signals that we now get 'digitally'. Also check to see if your TV and CB are on the same electrical circuit and if you *do* have a TV antenna, look at where that is in relation to the CB. Best of luck!
I'd first try putting on on the wire that has a mic on the end, and put the core in the end of the wire that's closest to the body of the unit. Hope this helps you Charlie Bravo! :)

Hey! Thanks a lot for this video, I had a similar problem with my at2020 except I was hearing the multiple radio stations near me through my headphones when I connected them both.

Appreciate you!
hello, I ran a triple shielded COAX cable for my subwoofer through the walls. Unfortunately, it was run too close to some electrical and it's putting hum on it. Would these eliminate that hum or do I need to rip[ drywall out and move the line?
Hello Dave! It's a great troubleshooting step to try putting one on the end of the cable that goes into the subwoofer. If you can get the COAX to pass through it twice, that would be optimal. Sorry to hear that your problem is in the walls! I hope you don't have to resort to moving the line.
Question ... I installed led light bars on my pickup , l now get static on my fm radio when the lights are on , will ferrite clips solve my problem and if so , which wires do I istall them ???
I have some 8' LED shop lights that Buzz and kill my FM radio what would be the process of using these to kill that buzz in my fm radio can't listen to any music , unless i turn the lights off and set in the dark any thoughts or help would sure be great, Thanks
Hi R. Freeland! I think the good news is, your lights being LED means this any interference is likely from the electrical and not the 'bulbs'. So if I were trying to solve this problem, I'd probably get one of the larger snap-on ferrite cores, pass the cable through it a couple of times, and snap it shut around the cable. I'd put it near the plug end. I hope this solves your problem! Also, for the FM radio, depending on what kind it is you can buy a third-party "amplified" plug-in FM antenna that will boost the FM signal. I use one on my stereo receiver because I live in a rural area. If you go that route, maybe plug the radio and the antenna booster into a different outlet than the shop lights!
So I got a sound module from the late 90's, the Roland Sound Canvas SC-8850. It's a MIDI music device which also has an alternative USB connection which allows for use of up to 64 MIDI instrument channels (4 parts of 16 tracks each). The USB cable type is the type B cable you'd see with printers throughout the 2000s, but I do notice that whenever I plug a cable in the USB slot it generates an additional level of hiss with a high-pitched screeching in its signal. When using standard MIDI cables there IS some light noise but nothing that obnoxious and at such a low level you'd have to turn up the audio interface to deafening levels to even notice. It seems that at the time, USB 1.1 ports hadn't really come up with shielding like more modern USB ports seem to usually have, and thus they might be more vulnerable to phenomena such as ground loop. As an additional observation I've noticed that none of the USB type B cables I've used for it so far have actually had ferrite cores. Could it be a worthy bet to try getting a cable with ferrite cores to clean this noise up? Thanks for your time.
Exactly the info I needed, thanks. I recently bought a good external condenser mic and last night was getting really bad hum/buzzing. Turned out to be where my extension cable was laying across my bed and my electric blanket was on. I get hiss anyway but was wondering if this ferrite would mitigate the interference if ever I go near such things again.
Really glad to hear it! Condenser mics pick up a lot of the environment, so that hiss may be mitigated by adjustments to gain--but I'm glad to hear you fixed the hum! :)
@@trentonbennettVO Thanks. I've since found that ferrite is bad for audio cables. The work initially very well, but degrade the cable and over time make it sound bad. They are better for less sensitive applications

HELP- I have an odd problem in my car. I have a 99 Camry that I switched over to all LED lights externally and internally. This concerns just the third brake light in the rear window. When I switched the third brake light over to an LED bulb, when the radio is on and I hit my brakes, the radio becomes so static-ee, I can’t even hear it until I let off the brakes and the light goes out. The radio’s antenna is built into the rear window, so Someone suggested I buy an RFI choke. I bought a small one and wrapped it around the red and white wires right at the bulb fixture, but it didn’t help the problem at all. I wasn’t aware that LEDs could cause RFI interference over an incandescent bulb. The choke did nothing whatsoever. I assume red is power and white is the ground and was wondering if maybe it just needs to be wrapped around the red wire only? It’s not easy for me to do this over as I have a bad back, so I was wondering if maybe I used the wrong size choke or maybe I’m barking up the wrong tree and the radio was at fault? Any insight to this would be extremely helpful. It’s so annoying to lose the station at every intersection, if you know what I mean? Thanks for any input anyone has.
, I see in another video, that. Ferrite bead core, its use to motorcycle, , can ask you, that ferrite bead core, gives high voltage current in ignition coil in motorcycle, it's true or not?
Hi lanzural1472. Ferrite is a ceramic compound loaded with iron. Iron is an electrical conductor, so it's physically capable of conducting electricity but I honestly wouldn't know anything about using it in the ignition coil of a motorcycle to produce high voltage current.

I've bought a USB sound card just for improvements for my audio quality, I plugged in the usb sound card into my pc and plugged my mic into usb sound card, it causes a lot of hissing sound I dont have any problems with my microphone and the xlr wire itself and I have found out that my soundcard causes the hissing problem, my thinking is the soundcard is grounded, my question is does this ferrite core will elliminate the hissing sound into my audio output? I am planning to buy and put it into my XLR cable, I hope you'll answer my question
I'm going to speculate here - trying a core is never really harmful, but if this were me I wouldn't be hanging my hopes on it. The XLR wire will be a better connection with more power for sure - I'm assuming the hissing sound card connection for the mic is your typical 1/8" (3.5mm) plug? Are you saying this USB Sound Card has an XLR connection too? Sometimes this is a matter of levels: if your sound card has a dial, switch, or software control for gain, that could be set in a way that picks up too much background noise. For example, I have a Razer Seiren Elite USB mic for streaming. If I turn the gain dial up on it, I get tons of hiss. So I have the gain dial pretty far down, in Windows I have the mic levels turned up, and I talk close to the mic. If I were in my home studio, I'd turn the gain dial a bit higher and the Windows mic level lower because the room is treated and it would be easier for me to talk a bit further away. Hope this helps!
Just added a vintage EQ to my rack that has tons of tranformers/coils. Suddenly I'm getting white-noise type static in my mic line. Gonna try some of these, hope they help. It's pretty bad and it all started with this one piece of gear I can't do without
@@WildBillQRO I think they helped somewhat but also adjusting all the preamps to 0 and starting over helped also routed audio cables as far as possible from power cords
That has to be really frustrating. Most speakers, even the simplest ones, are typically supposed to be better shielded from interference but sometimes this can happen. A ferrite core should help with that, and it's a cheap test to make sure. You can put one on the speaker wire where it connects to the speaker and that should help. Let us know if that works for you or you have to do something else. Good luck! I hope this takes care of it for you.
If you look at stuff that has them already put on from the factory, they tend to be at the device plug end (like the example I hold up in the video, or a laptop adapter where you'll see it on the end that plugs into the laptop and not the end that plugs into the wall), so I follow that pattern. Hope this helps!
Hello Trenton. I have a problem and appreciate it if you or someone else would help me solve it. Last year i bout an Xbox Series S and the fps after a certain hour at night improves significantly. i tried everything and i ruled out all the causes except for EMI Or dirty electricity. now i wanted to know that is it possible that these things would help me out and if not, is there any solution to my problem?
Sorry I don't always see these notifications abbasahmady-ih29r! The inside of a PC or console has a lot of parts that help keep the voltage flow stable to the console, so unless you're seeing brownouts (your lights flicker or dim), it's not very likely that the voltage in your wall is the culprit. "After a certain hour of night"...is this after having had the system on for a while? It's possible the unit is thermal throttling when it gets hot inside, and if it's not got decent airflow or it's a bit dusty or you live in a very hot place, this can make it more likely for the hardware to hit a performance wall and start slowing down. Depending on what game you're playing, the timing could be related to your Internet Provider slowing things down on your end, or it being a time of night that a lot of people on your network are streaming/gaming/etc. For example, if you're in an apartment complex and everyone gets the same Internet in the building, then there's a lot more people jumping online at a particular time. Network shouldn't interfere with FPS, but I'm also not sure if you're simply seeing slowdowns or you actually have some sort of FPS counter onscreen that's showing you the framerate changes. Either way, a Ferrite Core wouldn't do a great deal to help with voltage issues. It could help if the console is on WiFi and there's something interfering with the signal. Try it on either end to see if it works better close to where power plugs in or where the plug connects to the wall. The best way to get clean stable power when you can't control what's in your wiring is to get a Uninterruptible Power Supply (UPS). They have a battery that's there to keep power going for a while when the power goes out where you live, but they also monitor the flow of current and make it more stable to devices you plug into it. You also get the added protection that if a major surge came through the wall, the UPS would let the battery take the hit and protect your equipment from the surge. This is a TON of information I know...but I hope it helps you!
@@trentonbennettVO Hello. Thanks for your reply. About network problem, I'm sure that's not it. Because this also happens when my console is offline. And about excessive about of playing, I ruled this one out too. That leaves me with two possible reasons: 1-electricity issue which can be solved with what you proposed.2- or maybe it's some signal that keeps interfering with my console during the day, and it's gone at late night, which I'm not sure how to solve it. Thanks again for your constructive reply, Trenton.
My new boat sonar came with one but was slack on why, how and where to install it. Thank a lot hopefully it will reduce some of the visual "trash" on my fish finder .
Trenton, I am running a power cord to a Garmin Fish Finder head unit, I have loom covering the power cord for more protection. Can i clamp the Ferrite Core over the plastic loom, which makes it tighter, or this will not work as well not being direct on the cord itself? Thx
Hi great video Thank you. I am by no means familiar with emi rfi noise, so I got a question. I am using ferrite cores to supress noise on my pc quipment. From your video I understand I should be placing them near the ports of my pc. Am I correct in assuming that? I have a few cores around my power supply, usb, dvi and hdmi cables
Hi Roku! I'm glad this video helps you. That is one way to test, yes. Basically if you're having an electrical interference problem, a Ferrite Core can help you either troubleshoot or eliminate the problem because it shields the device and can block the bad signal...so if a USB device is getting interference from within the PC then stopping it before it goes down the wire might help. However, if the device is getting the interference from the surrounding air, you could also put one on the end too. I'll explain a bit. :) If you look at a wired XBox 360 controller, it's got a Ferrite Core built-in, near the controller, just to make sure the controller isn't getting problems from electrical interference. When my friend Veleka (the person this video was for) was having a problem with her USB mic, I suggested she put the core near the mic because that was more likely where the interference was being picked up. These would be times when it seems most likely that the interference isn't coming from the PC and is directly affecting the device connected to the PC. There was a time though when I had the front-panel audio of a computer creating noise in any headset that I plugged into the front-panel audio jacks. I put the ferrite core on the plug-end of the headset, the end that went into the computer front-panel headset jacks, because I wanted to stop the noise. I eventually realized that the front-panel audio wire inside the case that connected the motherboard to the front panel was getting the noise from something on the motherboard generating interference inside the case. I put a ferrite core on the end just before where it connected to the front-panel. When that didn't help, I replaced the internal audio cable and all was well. I realize that's a lot of typing! But I hope it helps you. This gets a bit technical but also explains the nature of what causes electrical interference: www.emfservices.com/electric.htm

Hi Trent, I replaced may tail lights with LEDs now my reverse cam started having noise in the video everytime the brakes are engaged/brake lights are on.. Where would it be ideal to place the core to remove the video noise?.. I am still currently waiting on the core I ordered online to arrive..
I would place it as close to where the camera feeds into the head unit as possible and also make sure the camera and tail lights are both properly grounded / the grounding wire hasn't come loose. Hope this helps you!
Hey mate Josh from over in Australia great video. I also wanted to ask you would something like that help in a car situation not so much for stereo more so with my ngauge and aftermarket tuning software etc on a basis that there are so many cables in and around the car ?.

Hi! RUclips (or maybe Google?) periodically dumps my comment notifications into a different category and I don't always catch my comments - sorry for the delay. I'm glad to hear you're both working together to solve the problem! There are some good suggestions in this document from "Ham Radio University" that might apply to you. hamradiouniversity.org/wp-content/uploads/2019/01/RFI-hamshack-20190106.pdf Most computer equipment has decent shielding on the cables and such, but it's not guaranteed against unusual signals like this, so ferrite might be a good start...but you may also find you need some other shielding solutions or a look at where his antenna is located and how it's oriented. I hope this helps you and I'll be the first to admit this is beyond my own area of expertise! :) Best of luck though.
Hi Kinang Eagle! Yes, they are the same thing, called different names (even sometimes called a 'ferrite bead') and yes, you can put them over braided cables - I did so in my VO studio to kill a faint hum in my studio monitors (speakers). Hope this helps you!
G'day from Australia, Do you think one of these might help improve the signal I get on my AM radio in the Chevy? The radio stations Iisten to are about 150klm away and although the signal is okay when driving, it goes all screamy when I put my foot on the brake pedal and sometimes when I use the indicators. I have a couple of them here and was thinking of putting my antenna cable through one two times.
Hi, i want to use some ferrite chockes on signal wires of a cnc machine. As they have a certain impendance at a certain frequency, other than fitting tightly on the wire, the bigger impendance would mean more efficiency ? Thank you.
Hi Ionut Popa! I'm not quite sure I follow the question, but I think the gist of it is that if you have a larger core that the cable can pass through more than once, this would more efficiently battle any stray interference. I hope this helps you!
I recently bought Asus ROG Strix laptop and it keep having this annoying hissing noise when i plug it in and no noise when its on battery. I researched internet about it and find out its a common problem called coil whine with this particular series of laptops. So, i wanted to know is it possible this solution will fix this problem or should i just return the laptop and buy some other one?
Yikes! Is the hissing noise only in headphones or does it come through the laptop speakers as well? If this is coil whine, that's difficult because it means there's something physically wrong inside the hardware--one or more motherboard components are generating interference. If this problem only seems to happen when you use the headphone jack, then try this: 1) if you're using a headset, see if the hiss goes away when the mic is muted or not plugged in at all; 2) If you're just using headphones, try a different pair; 3) With only a pair of headphones (no mic plugged in), see if the hiss gets louder or softer when you raise or lower the volume--specifically, play a video where the Windows system volume is low and you use the video player to raise the sound, then try lowering the video player's sound and using the Windows system volume higher/lower to see if the hiss gets louder with the system volume or with the player's volume. I do love me some ASUS hardware, but their support can be hit and miss. If this is a recent purchase, definitely reach out to them in the event you need to replace the laptop--the sooner you get a ticket in the system, the better negotiating power you have. Let me know how this goes and what you observe (my questions here)!
@@trentonbennett4864 Thanks for replying. It doesn't come from speaker or Headphone but from somewhere under the keyboard. I ran following solution i found on a forum- reg add HKLM\System\CurrentConsoleSet\Processor /v Capabilities /t REG_DWORD /d 0x0007e066 on command prompt and it somehow made it go away. Now very rarely it makes that noise abd even if it does its for a second or two. I have no idea what registry i added and what it does. Please let me know i didnt do anything wrong.
@@lonelysoulshivin8256 interesting - well, first off don't panic. You haven't done anything "wrong" and you'll probably be just fine. I read up on your registry key solution. Long story short, a processor is also a device with electricity running through it--and the things that manage that electricity can be very complex. Today's processors--especially in laptops--are much smarter about not draining all the juice and running at full power all the time. So what they do is ramp up the processing power on demand and then idle it down when you're not doing anything particularly intense. From what I can tell, the conditions created by one specific "idle state" (of many) were creating just the right circumstances for electrical noise. All you've done with that registry key is told it "don't use that one", and the system can work around it. Short story long, this explanation "It not really the cpu that whines but rather a coil on an inductor on the motherboard near the cpu voltage regulators" from superuser.com/questions/121883/any-way-to-disable-specific-cpu-idle-cx-states . If it were me, I'd see if I could get ASUS to send me a replacement if I'm still in the purchase window, and then maybe my replacement wouldn't do that--but if it did, now I'd know a registry key I could use to fix it. Good luck! Let us know what you decide to do.
I have a camera system in our farm tractor. When ever I turn on the camera the tractor radio looses reception almost completely this is on the FM side not sure of AM. So will these take care of the problem? I am assuming it would go on the camera part of system but exactly where. The power wires or the camera cable itself? Thanks
This may help, but I would also look into all the connections and make sure nothing's shaken loose *and* (most important) that everything's grounded correctly. If this is a camera system that wires into the fuse box that can be one point where things can come loose--I had this happen with a Dashcam because the wiring required me to wrap a wire around one leg of a fuse, then plug the fuse into the box. I hope this helps you!
hi Trenton, great video on describing what ferrite rings do. i am getting interference from my wood lathe to my webcams i am wondering if these would help if i put them on the wood lathe power cords.
I really need your help and your video gives me some hope. For 5 years since I bought Powerline adapter the box devices to transmit Ethernet UTP signals using the power sockets on the wall and the house electric wires to establish the connection my speakers started to crackle. When I increase or decrease the volume from the speakers to maximum the crackle sound is starting to be heard . The power wire of the 5.1 speakers is coming from the subwoofer and doesn't have any kind of ferrite core on it. If I attach the ferrite core on the speakers power wire will it help to eliminate this EMI crackling issue?
I hope I can help you! And I apologize for the delay - I've been a bit overrun these last few weeks but I finally have breathing room to look this over. First, let me ask if you could plug the powerline adapter to a different outlet in the room, and even better yet if you happen to know of an outlet that's on a different circuit than the outlet you use for the computer. If it's not a pain to try to do, this might be a good way to separate out the electric flowing into the device you're using from the electric that's being used to piggyback data on your powerline adapter. There's a really interesting article here that goes into some detail. www.cablinginstall.com/home/article/16467315/how-utp-deals-with-interference (1 of 2)
Next, let's talk about the ferrite core. I think it would help you, and yes, I'd be putting it on the speaker's signal wire, though the power wire might also be a place to try. I'm assuming this is a powered subwoofer with its own power adapter. If you can plug even the subwoofer in a different outlet than the powerline adapter, that too is a good idea. But if nothing I've suggested so far helps, take a look at this video about a Balun Core - same principle but with a simple (literal) twist of winding a cord around the choke. ruclips.net/video/JhAPJISUjB8/видео.html
So to recap, I'd try 1) different outlet for the powerline ethernet, preferably on a different circuit; 2) Ferrite core on the audio wire and/or the power line for the subwoofer; 3) Balun style core like the video (and you can read more on Wikipedia to understand it): en.wikipedia.org/wiki/Balun I really hope this helps you! :)
Hi Naresh! Sorry for the delay - I don't always get my comment notifications for some reason. If it's humming when you power it up, that shouldn't be a problem. I have a pair of subwoofers that always make a brief hum and 'pop' sound on power-up and I've had them for many years. If your subwoofer continues humming once it's on and powered up, then yeah, that might be a bad ground or RF, but it's difficult to troubleshoot that. These ferrite core things are a cheap way to troubleshoot, and if putting one on the power cord doesn't help, you can also buy various kinds of plug-in gadgets that 'filter' the power (look for 'power conditioner' or 'line conditioner', or 'ground line voltage filter'). I once used a device by Ebtech called the 'Hum-X' to keep a computer's grounding issue from making a hum in my headphones. I hope this helps you!
Also: If you use only one choke should you place them at the end of the cable or in the middle? If you use 2, 3 or 4 chokes where should you place them?
Hi Giovanni! I'm suggesting that if you have a problem with background interference, then you try connecting one at the area where you think there might be a problem. If it doesn't solve the problem, try it on another device. For example, my friend's USB mic seemed to be picking up a hum, so she connected one to the USB cable for the mic. I had a problem with speakers picking up a buzz, so the cable the speakers plugged into was where I tried it. It may not solve the problem but it does help in troubleshooting--and I hope this helps you! :)
I found one lying around and wondered what it was. Now I can start recording better! That aside, I do notice that some charging bricks would charge my phone and I'd feel a sort of vibration that feels like static electricity, but I tried searching online for why it happens but no results from my search. I might try using this on phone's charging cable to see if it does anything.
The core doesn't really make a difference as far as sending power down the cable is concerned, so it shouldn't make a difference - it's there for the benefit of reducing electrical noise. Hope this helps!
I fitted drls ( daytime running lights) to my car front grill, now my radio dab signal is terrible Where should I fit the ferrite core? To the dab areial cable or the drls cable? And how many?
Hi Lucio! I'm not sure how you're wired--for example, if your DRLs end in a 12V cigarette lighter plug or if you're running the wires straight into the fusebox (or, if so, whether it's wired to the fuse box under the hood or inside the car). So I would take a guess that your DAB aerial cable should have one attached, somewhere close to where it plugs into the radio. If you have slack, wrap the wire a time or two around the core like I do in the video, and just one should do it, if that's what's going to fix the problem. If the DRLs mention that they need to be grounded to the vehicle frame, be sure that they are actually grounded onto the bare metal of the car, because that can also be a source of problems like this. Last, if the ferrite cores don't work, and the maker of the DRL doesn't have any suggestions for you, you may need to try a Ground Loop Isolator. I had a car stereo with interference noise where I had to put one on to properly compensate for a bad ground inside the car stereo head unit itself. I hope this helps you! Definitely a) check all your connections, b) talk to the maker, and c) see if anyone else has also run across the problem, in addition to trying this cheap & easy troublshooting step. :)

@@luciocancellara4995 that helps! I would suggest putting a core on the antenna wire near where it plugs into the car stereo, and if you can, wrap the wire a time or two through the core. But also double-check the ground wire. I had to do after-market fog lights on a car like you've done, I just didn't run into this problem or I could be more help. Good luck!
Hi aGoodShepherd! When I troubleshoot, I only use one. Manufacturers put them on one or both ends, I tend to focus on the point where the wire goes into something (like a computer), so I'd start with one near the point where the device connects. If you have a serious interference problem, there are a lot of other ways to solve it; this is just a great initial troubleshooting step that often takes care of minor problems. It's a way to determine whether the problem is RF interference as opposed to a problem with grounding. Hope this helps you!
I get high pitched Morse code like noise. Home studio. Worse on guitars (DI) but faint on vocals too. My studio is in the same room as my electrical mains in and my PC sits next to the 100A mains in if that makes a difference?

Hi Volvo5turbo! Does the noise sound anything like these? ruclips.net/video/uPYyrS7fc7g/видео.html There are a lot of things that can cause interference, both on the wire and in the air, so the ferrite core/bead/choke/whatever is one way to troubleshoot. It would be awesome if the noises in the video I link to here are what you're dealing with because that would make the problem as simple as "turn off your cellphone when you head into the studio". If this isn't the case though, also take a look at the deeper dive on Scotties Tech here: ruclips.net/video/veIL3GeqA68/видео.html This will give you an understanding of what exactly is going on and how to apply these things.

Good luck Kristopher! This is a cheap way to possibly fix such problems...and if it doesn't you can also look for a Ground Loop Isolator. I had a car stereo where I had to put one of those on. This Wikipedia article will explain a bit about how those work, and why you might want to check what frequency range the interference is coming in on en.wikipedia.org/wiki/Ground_loop_%28electricity%29
@@trentonbennettVO thank you so much! I am using a ground loop isolator and it works great. I might need another one. I have yet to wrap the ferrite rings with my coax and some with the power leads, ill let you know the outcome! Thank you for your help
Correct! The ones that can be are easy to tell because they'll have a clasp and a seam that you can pry open...but some manufacturers embed them in the wire, and so you'd have to cut the cord open to get to it, and that would expose the wire. Good question! :)
A clip-on is effectively only one turn onto the core. The inductance increases as the square of the number of turns on a core, so, passing the wire around again is 2 turns which will give you 4x the inductance of the straight clip-on.
Thanks for this, by the way - a lot of people have been reading these comments and you've just helped them too! :)
Super clear, Trenton. And thanks to you, I found a ferrite core on a cable I have, and now I don't have to wonder what the heck it is!
You're welcome.
Would the ferrite core help prevent interference caused by the CDI (ignition system) to the radio receiver of my two-stroke powered RC truck?

My issue is a constant, extremely high pitched tone that is audible whether or not there is any other signal being sent to these old Pioneer 77 speakers, from a Pyle surround sound speaker amp
Ouch. I had that before with a car stereo head unit, and it drove me bonkers because it was audible in everything it played back! Super-disclaimer: I'm not a sound engineer! :D But that said, these kinds of things can have multiple causes, from EMF (which is where the cores come in) to a bad ground (where you can either try another outlet or try using a power conditioner) to bad capacitors that give off noise (which leaves you with 'repair or replace'). I hope you're able to solve the problem though. My car stereo, I'd tried cores and extra grounding wires and ultimately had to replace the unit. If the amp is relatively new, there may be a warranty for those kinds of issues or an easy repair option.
The work on XLR cables, not just power cables?
Yes
I bought these new logitech usb computer speakers and I hear this high pitch noise coming out of them especially when I'm not playing anything, I think the problem is with the grounding. Will this ferrite core help with this issue?
It can help, yes. If you can try putting a core on the speakers at the USB cord where that plugs into the computer, that might be your best bet if the noise is coming from a bad ground on the PC. I say that assuming it's just a USB connection to the computer. If it's also needing you to plug in an audio cable (say, to the stereo jack on the back of the computer), then a core on that cord would also be a good idea to try.
Good luck! I hope this helps.
Very clear for the non-electronics type. Very clear and useful for anyone with funny noises in their radio or other electrical/electronics device.
Thanks Forrest! I really appreciate hearing that and I'm glad it was helpful to you. :)

Will a ferrite core improve reception from a dipole antenna receiving at 459 MHZ...if I add a ferrite core around a RG58?
That's a good question! I know it won't hurt, since the primary benefit is filtering out higher frequency. It can't hurt to try, I'd love to hear if you find a difference. It's mostly designed to solve an RF interference problem though.
Couldn.t you use copper wire to loop around the lead? 25 or more turns around the effected line?
You certainly could! I originally did this video to help out a friend to understand the basics of what Ferrite cores are and how to clip one onto their mic to solve an interference problem--but yes, while putting a Ferrite Core on can be a simple test and provide a quick fix, introducing multiple turns of copper around the lead is certainly another option. Thanks for sharing this! :)
Is ferrit more useful on subwoffer ore speakers????
Hi Techmania! It is useful for either. A subwoofer is a very big speaker, so it will work for either. The use is to remove any RF interference that--for a speaker--might cause noise in the speaker. I hope this helps you!

It might! I'll share what I just said to someone else with a similar problem: The noise might be interference from a phone or other wireless device that a ferrite core might not be able to mitigate. I would put the core as close to each speaker as possible (one on each speaker cable). Check out this video and see if any one of these is the sound you're running across - ruclips.net/video/uPYyrS7fc7g/видео.htmlsi=mY6SDCu9P32Jik5N - if so, it's a matter of having to keep the phone or other wireless device further away from the speakers to avoid this interference. Older speakers can be less well shielded than newer ones, but this is why I don't bring my phone into my studio when recording--sometimes my newer studio monitors pick up the buzz too.
I hope this helps you! Sorry I don't always get to these comments right away.
Thanks! I didn't think about wrapping the cable to make it pass two time in the bead!
I’m getting RF interference on a FM stereo I’ve tried a lot of things but have had no luck removing it. The transmitter has two chokes on the coax, one at the antenna and one close to the radio. The coax is wound on a a piece of PVC pipe on the mast 6” down from the antenna. I used 11ft of coax on the PVC pipe. An amateur radio operator gave me this information and said it would work. The stereo is not a new one and uses a “T” type antenna. Can you please suggest a cure. Thank you for your help.
Does it work with smartphones interfering with speakers? I'm using 2 ferrite cores, I've tried placing them on the speaker cables, power cables, close to the speaker itself, close to where the speaker plugs in, and pretty much any variation of that, but I still get the crackling noise if my phone is close to the speakers (50cm). I am using some old speakers (Trust Soundforce 1200), but should that matter?

Does this work for film / digital noise on videos ?
It works for equipment that's generating noise, like a speaker or microphone. If you did have some sort of setup that was capturing video and there was interference causing noise, it might work for that. Not sure what your specific setup is, but basically anything that might be getting EMF interference from nearby and has a wire sending a signal. Hope this helps!
@ definitely did I took a chance and got a decent amount off Amazon I added them to my lg c3 power cord and all my hdmis apply tv Xbox and sound bar with a subwoofer wireless and 2 reach speakers connected because I noticed my lgc3 was getting more visible film grain and noise and almost static on the picture so added them and even to the power cord because I have at least 9 cables running to one power surge in my wall which is all that I just stated above and it definitely did help ALOT but still some noise and artifacts which I’m sure is from the films streaming in general but they definitely do help a tone and this video definitely helps me with that choice of taken the chance so thank you!🙏

Hi I have a humming problem from my turntable in my hi fi set up. Probably a grounding loop. But I can't seem to fix it . I have separated the power cables from the phono/ RCA cables . Do you think fitting some on the turntable power cable. Or on the rca cable . Your thoughts would help on this matter I'm sure. Thanks Gerald
Hi Gerald! I don't always reply fast, but I hope this is still useful to you. Yeah ground noises in audio are a pain to troubleshoot! But yes, trying a core on the power cable is one way, as is trying the RCA cable. If it's not a pain to move around, plugging into another wall outlet on another circuit is another way to test. You can buy third-party ground-loop isolators like the Hum-X, but the success is hit and miss because it depends on whether the ground problem is at the wall versus somewhere else in the chain. I hope this helps you!
I've been getting interference on speakers in the hall whenever the HDMI cables are running. Hopefully I'll be able to put a few of these on around the place and solve the issue.
Hi habitangleft! I hope this helps you. I don't know what cables you're using, but maybe with luck they'll be better shielded from EMI
What benefit(s) would be achieved if ferrite cores were added to my marine/boat Humminbird/Garmin electronics...GPS w/down-vision, side Imagining and sonar?
Hi John! Most manufacturers use the right quality cables for electronics and some go an additional step and put one of these on their cables at one or both ends, so you shouldn't need one. You wouldn't really benefit from adding one unless you're experiencing a problem with interference and then you want to troubleshoot whether it's a grounding problem or a problem with signals coming through the air around you fouling up your equipment. Usually that sort of problem comes from nearby electronics or being close to a radio tower, etc. It's unlikely you'd be experiencing that in your scenario with side and sonar as the emitters are aimed away from your boat and the equipment (especially the Hummingbird and Garmin brands) should be assembled in good quality and go through Quality Control (QC) checks before it gets boxed up and sent to the store. That said, this is a really good article to explain it a bit more in detail - www.rfpage.com/electromagnetic-interference-and-compatibility-in-radio-frequency/ - the bit about "Radiated EMI" is the problem a ferrite core tries to solve, and in the section "How to avoid electromagnetic interference", the passage about "filtering" refers to devices like a ferrite core. The English isn't perfect in this article, but I like the bits about "How [is] EMI Generated?" and "Sources [of] EM Radiation". Hope this helps you! :)

@@JCASTELLUCCIOJR Rats! I was hoping that would help you, but you might have to try multiple ferrite cores to see if you can kill the interference. Hope you can find a solution, I know how maddening it can be sometimes when things that shouldn't be going wrong, are going wrong weirdly. :-/
So my microphone picks up some sort of radio frequency that comes from the outside, its this trucker that I assume is just using this really powerful radio. I can hear him talking sometimes through my microphone, and I was wondering if putting a ferrite core(s) on the XLR cable would help or not, I already have a star quad cable and I still pick up the frequency, although the frequency stops when I wrap my hand around the microphone end of the cable? It might be that the end that connects to the microphone might not be properly grounded? Or the cable in general isn't properly grounded, I don't know. I ordered a cloudlifter CL-1 recently and I hope that this can somehow clean up the frequency, but if so I don't know. I don't have access to properly grounded plugs in my home, I think it might be that, and if so I don't know what to do :/
This would definitely be a case where you're getting RF Interference, so yes: I'd try putting one on the XLR cable at the end where it plugs into your interface (pre-amp, cloud lifter, etc.). The Cloud Lifter is good for gain staging, so it might help if you're using a Dynamic or Ribbon mic (I'm told it won't work for Condenser mics). One other thing I read was to make sure the XLR cable isn't touching or laying across any power cables. There's also a forum I found where both ferrite cores and hum eliminators were used to solve the problem of CB Radio coming in over the wire - I hope this helps you! homerecording.com/bbs/threads/picking-up-radio-frequencies-whyyyyyy.14830/
Can it work on analogue CCTV video?
Hi adhmekathrada! So many comments I sometimes don't catch 'em all right away--sorry! But yes, if you're getting signal interference, it *might* help, and you'd have to try it in a couple of spots. I'd start by putting one close to where the camera plugs into the recorder or monitor, then if that didn't help try it on the power cord close to where it goes into your setup. I hope this helps you!
Can you use these to reduce noise in a chain of effects for guitar? Where would you use them - audio guitar cable between effects pedals and/or power supply cables? I know guitar pickups also pull in noise, specially single coil pickups. I am just trying to reduce as much noise? Or are these not needed if the guitar/patch cables are shielded?
You're right that good shielding is supposed to solve this problem and you shouldn't need it. If you're getting noticeable noise, that's another story, and that could be a bad grounding or EMF. I'm not a sound engineer like some of the people I know, but if I can ask one of them for more detail, I'll share it with you. As far as using a ferrite core to reduce noise in a chain of effects, you could try connecting it at various points in the chain to see if the noise goes away at any particular point in the chain. Hope this helps you!
@@trentonbennettVO Thank you very much for the ideas. I'll try those. Although, I came across some sound guy on youtube this morning that said he's against cores on audio cables because it increases impedance on an already low signal. But I think like you said I should try at different points. There's no hurt in trying. It's not like something is going to arc!!!
Thank you again for your suggestions and for your channel.
@@t2dev I can see the sound guy's point, yeah, if that's a line-level feed it is a low signal. I do tell folks I'm not an engineer--I know several now, but that's outside my range :) I'm really glad this was helpful to you - thanks very much for letting me know how it's been going!

hi great explanation does it work on adsl / dsl line Attenuation ?
Hi Artin! I did some reading specific to ADSL lines and the answer appears to be, "not really." The only situation in which it *might* help would be if you put one on the power line to the ADSL modem, and that is if the power is the source of RF noise--I'd place it on the end of the cable that plugs into the modem and not the end of the cable that plugs into the power outlet in the wall. Even then, there was some debate as to whether RF could be a problem for an ADSL signal because the ADSL signal flows in a "differential mode" (current flows in opposite directions in each conductor inside the wire, resulting in a net magnetic field of zero). IF your ADSL line also happens to be your phone line AND you're hearing interference when you talk on the phone, THEN it *might* be something you could use to reduce noise on the phone line.
So the bad news is, you likely wouldn't get any improvement specific to the ADSL by placing a core on the data cable.
The good news is, these cores are a very cheap way to troubleshoot, and on the power cord, they might help reduce or remove any problem related to RF generated by the ADSL modem. I hope this helps you!
I have a 90's lexus with a tape player. Going to try this for my car tape adapter to aux, that I attached to my iphone. Always gives me fuzz on the audio. I could get a bluetooth car tape adapter, but the volume is much louder on the old-school tape adapter 3.5mm aux audio to iphone.
Hey, if you can, let me know if that worked. Ah, nostalgia - me with my tape adapter and my Discman that skipped any time you hit a bump. Clever to use that as a hack for your phone since it's just a standard aux jack. I wonder if the volume on the old-school adapter is louder because it's expecting a line-level signal and it's getting amplified audio? See if the quality is still good if you turn the phone's volume lower and let your car's head unit handle the volume. You might find a sweet spot of great sound!
I got mine to reduction EMF exposure. Are they effective for that purpose?
Yes! They are there to help reduce problems from EMF. Hope it is helpful to you!
Does it matter how tight they fit? I have assorted sizes, and one is a little loose and the other is a little snug...
Not at all! Just that the cable passes through the core is all that is necessary, and if it can pass through more than one time, that's better. :)
do you have a video where we can see live the action of the ferrite core modifying or reducing some external noises from a line?
I haven't been able to find something like that, but if you don't mind a deep dive, this PDF explains with visual charts how the effect works: audiosystemsgroup.com/SAC0305Ferrites.pdf
Here though is also an example of how the interference can be affected by anything coming in between the source and the affected item (in this case, a hand altering the signal as it interferes with a classic Atari 2600) ruclips.net/video/CeDYd6Fci9g/видео.html

I have cruise control by Rostra company on my truck 2011 ranger I-4. Keep disconnect itself so I test turn air conditioner on and off affect cruise control disconnect CC itself. My truck battery is old make alternator make very light charge the battery. Do I need add ferrite power cord 12v to CC ? Help to reduced static electricity charge to CC ??
I'm honestly not sure on this one! I've had mechanics tell me sometimes an engine component isn't correctly grounded, but you also mention the battery is old, and in the last 15 years or so I've experienced that once a battery starts to go, it just doesn't put up with being recharged for very long. I'm not sure which of Rostra's products you have and what that configuration is (like is this a speed limiter on a company vehicle?) but I'd probably start by reaching out to them. This link can let you specify exactly which product you need help with: www.rostra.com/support/
Do these eliminate radio frequency noise? I'm trying to remove an entire radio station that's coming through my speakers in my home studio. I've bought a power conditioner, I just ordered these ferrite rings... it's not working. Any suggestions?
H, I attached a Rodin coil (without a ferrite choke ) like the Qi coil on my sound to frequency converter which is connected to my Rockville blutube amp (70 watts per channel) and for unknown reason to me that channel stopped working. It’s possible that when I unhook one of the connections of the Rodin coil the sudden collapse of magnetic field traveled throug the wires and damaged my equipment? Is this possible?
Ergh...maybe? You're definitely far afield of my wheelhouse, but from what I can tell, since a Qi coil *generates* an electromagnetic field, it sounds like that might run counter to trying to handle an electromagnetic interference problem. I would reach out to Rockville and ask them this question if you haven't already. I'm definitely not an electrical engineer with a deep understanding of Qi and Rodin coils. If you haven't tried this already, one thing you might try is to unplug the amp, disconnect everything from it, then do a power drain (you hold down the power-on switch for about a minute to make 100% sure any residual charge within the circuitry is expended). Then connect something simple, plug it back in, and try to run sound without any coils or other modifications. Jeez, I hope you are able to get the problem solved!
How many Ferrite Cores should you generally use on a faulty cable?
Hi jonnystevens9589! It's a good question, but hard to qualify. If there's something faulty about the cable and you can't fix or replace it, then, it's not necessarily a number so much as a question of "what's happening" and "where should I try this?" For example, let's pretend this is a simple pair of speakers connected to a turntable and you're hearing noise. You could put a core on each speaker close to the speaker and if that didn't work, then instead put one on the electrical cord close to where it goes into the turntable. Unfortunately, since this is a "possible" simple fix, and there's more than one cause of the problem, it could ultimately be some other issue like a bad ground or coil whine inside the thing, etc. and more of 'em doesn't really do much to help. I hope this does help you.
had bluetooth reception problems, turned out the monitor usb in was emitting noise, snapped a bunch of them on before i narrowed it down to that one.
Glad to hear this helped you! It's the simplest solution - and yeah, you had to do that fun legwork of trying to nail down which one it was. Congrats on solving the problem! :)
@@trentonbennettVO Yea just scattergun blast solution, hit everything until it stops, got it to quiet down even more after I dealt with a cheap knock off laptop power adapter as well.
Can I put too many on the cables of my stereo?
It's not really possible to put 'too many' on, no, but if one at the end going into the receiver or one at each end of the cable should tell you whether RF is the problem. Hope this helps you!
No but I have one that is on my usb streamer cable and I have one that is on the power supply for the streamer and the amplifier. I am thinking of the speaker cables because I have a few more leftover.

Question. Connected a record turntable to my Denon amp. Two connectors plus an earth cable. I get this hum though, Could ferrites help here? Thanks
They could, though that may also be a grounding (earthing) issue. You can of course put a core on the two connectors, I would also check that I've got the earthing correctly connected and I'd also see if I could plug the turntable into a surge protector (or if you have done so, try a different surge protector or a different outlet). I hope this helps you!
I have a TV in my living room and I run a cb in my man cave and I am getting feed back noise from the TV wen she turns it off and on will this help me get rid of it
It's certainly worth a try. If the TV is getting an over-the-air signal that might be one reason why the interference (as in, you have a digital antenna in your home and maybe that's why there's as much interference as there is). Usually most TVs are well shielded on the inside and tend to operate over wireless as 'WiFi' instead of the traditional over-the-air signals that we now get 'digitally'. Also check to see if your TV and CB are on the same electrical circuit and if you *do* have a TV antenna, look at where that is in relation to the CB. Best of luck!
I've got some interference in my GMRS radio. Which wire should I install the ferrite core on? Thanks!

Hey! Thanks a lot for this video, I had a similar problem with my at2020 except I was hearing the multiple radio stations near me through my headphones when I connected them both. I bought two ferrite cores, put each on the end of the mic and headphone wires, and it helped stop all the noise from coming through except if I mute everything and really try to listen to it. Appreciate you!

What if this interference ring is removed?
hello, I ran a triple shielded COAX cable for my subwoofer through the walls. Unfortunately, it was run too close to some electrical and it's putting hum on it. Would these eliminate that hum or do I need to rip[ drywall out and move the line?
Hello Dave! It's a great troubleshooting step to try putting one on the end of the cable that goes into the subwoofer. If you can get the COAX to pass through it twice, that would be optimal. Sorry to hear that your problem is in the walls! I hope you don't have to resort to moving the line.
Did you manage to solve the problem?
Can it be used on a refrigerator that keeps tripping a ground fault? Use more than one? Place near appliance or socket?

Question ... I installed led light bars on my pickup , l now get static on my fm radio when the lights are on , will ferrite clips solve my problem and if so , which wires do I istall them ???
I have some 8' LED shop lights that Buzz and kill my FM radio what would be the process of using these to kill that buzz in my fm radio can't listen to any music , unless i turn the lights off and set in the dark any thoughts or help would sure be great,
Thanks
Hi R. Freeland! I think the good news is, your lights being LED means this any interference is likely from the electrical and not the 'bulbs'. So if I were trying to solve this problem, I'd probably get one of the larger snap-on ferrite cores, pass the cable through it a couple of times, and snap it shut around the cable. I'd put it near the plug end. I hope this solves your problem! Also, for the FM radio, depending on what kind it is you can buy a third-party "amplified" plug-in FM antenna that will boost the FM signal. I use one on my stereo receiver because I live in a rural area. If you go that route, maybe plug the radio and the antenna booster into a different outlet than the shop lights!
So I got a sound module from the late 90's, the Roland Sound Canvas SC-8850.
It's a MIDI music device which also has an alternative USB connection which allows for use of up to 64 MIDI instrument channels (4 parts of 16 tracks each).
The USB cable type is the type B cable you'd see with printers throughout the 2000s, but I do notice that whenever I plug a cable in the USB slot it generates an additional level of hiss with a high-pitched screeching in its signal.
When using standard MIDI cables there IS some light noise but nothing that obnoxious and at such a low level you'd have to turn up the audio interface to deafening levels to even notice.
It seems that at the time, USB 1.1 ports hadn't really come up with shielding like more modern USB ports seem to usually have, and thus they might be more vulnerable to phenomena such as ground loop.
As an additional observation I've noticed that none of the USB type B cables I've used for it so far have actually had ferrite cores.
Could it be a worthy bet to try getting a cable with ferrite cores to clean this noise up?
Thanks for your time.
so I can use that to block interferance when i charge both bluetooth audio reciver and non bluetooth speaker at the same time?
Exactly the info I needed, thanks. I recently bought a good external condenser mic and last night was getting really bad hum/buzzing. Turned out to be where my extension cable was laying across my bed and my electric blanket was on. I get hiss anyway but was wondering if this ferrite would mitigate the interference if ever I go near such things again.
Really glad to hear it! Condenser mics pick up a lot of the environment, so that hiss may be mitigated by adjustments to gain--but I'm glad to hear you fixed the hum! :)
@@trentonbennettVO Thanks. I've since found that ferrite is bad for audio cables. The work initially very well, but degrade the cable and over time make it sound bad. They are better for less sensitive applications
@@ArcanePath360 yikes! I hadn't heard that a ferrite bead/core/choke would degrade a cable, and I can't find anything on it. Do you have a link you can share?
HELP- I have an odd problem in my car. I have a 99 Camry that I switched over to all LED lights externally and internally. This concerns just the third brake light in the rear window. When I switched the third brake light over to an LED bulb, when the radio is on and I hit my brakes, the radio becomes so static-ee, I can’t even hear it until I let off the brakes and the light goes out. The radio’s antenna is built into the rear window, so Someone suggested I buy an RFI choke. I bought a small one and wrapped it around the red and white wires right at the bulb fixture, but it didn’t help the problem at all. I wasn’t aware that LEDs could cause RFI interference over an incandescent bulb. The choke did nothing whatsoever. I assume red is power and white is the ground and was wondering if maybe it just needs to be wrapped around the red wire only? It’s not easy for me to do this over as I have a bad back, so I was wondering if maybe I used the wrong size choke or maybe I’m barking up the wrong tree and the radio was at fault? Any insight to this would be extremely helpful. It’s so annoying to lose the station at every intersection, if you know what I mean? Thanks for any input anyone has.
So, how is ferrite manufactured and what are its types? Where can I get a complete research on it? I want help, please...

good day! I've bought a USB sound card just for improvements for my audio quality, I plugged in the usb sound card into my pc and plugged my mic into usb sound card, it causes a lot of hissing sound I dont have any problems with my microphone and the xlr wire itself and I have found out that my soundcard causes the hissing problem, my thinking is the soundcard is grounded, my question is does this ferrite core will elliminate the hissing sound into my audio output? I am planning to buy and put it into my XLR cable, I hope you'll answer my question
I'm going to speculate here - trying a core is never really harmful, but if this were me I wouldn't be hanging my hopes on it. The XLR wire will be a better connection with more power for sure - I'm assuming the hissing sound card connection for the mic is your typical 1/8" (3.5mm) plug? Are you saying this USB Sound Card has an XLR connection too? Sometimes this is a matter of levels: if your sound card has a dial, switch, or software control for gain, that could be set in a way that picks up too much background noise. For example, I have a Razer Seiren Elite USB mic for streaming. If I turn the gain dial up on it, I get tons of hiss. So I have the gain dial pretty far down, in Windows I have the mic levels turned up, and I talk close to the mic. If I were in my home studio, I'd turn the gain dial a bit higher and the Windows mic level lower because the room is treated and it would be easier for me to talk a bit further away. Hope this helps!

Got 2 5v cables running past the aerial and when ever there on radio is not so good noisy
there is a radio station playing through my computer speaker and i didnt do that. will this thing stop that?
That has to be really frustrating. Most speakers, even the simplest ones, are typically supposed to be better shielded from interference but sometimes this can happen. A ferrite core should help with that, and it's a cheap test to make sure. You can put one on the speaker wire where it connects to the speaker and that should help. Let us know if that works for you or you have to do something else. Good luck! I hope this takes care of it for you.
Does it matter which end of the cable I install the ferrite bead?
If you look at stuff that has them already put on from the factory, they tend to be at the device plug end (like the example I hold up in the video, or a laptop adapter where you'll see it on the end that plugs into the laptop and not the end that plugs into the wall), so I follow that pattern. Hope this helps!

Hello Trenton. I have a problem and appreciate it if you or someone else would help me solve it. Last year i bout an Xbox Series S and the fps after a certain hour at night improves significantly. i tried everything and i ruled out all the causes except for EMI Or dirty electricity. now i wanted to know that is it possible that these things would help me out and if not, is there any solution to my problem?
Sorry I don't always see these notifications abbasahmady-ih29r!
The inside of a PC or console has a lot of parts that help keep the voltage flow stable to the console, so unless you're seeing brownouts (your lights flicker or dim), it's not very likely that the voltage in your wall is the culprit. "After a certain hour of night"...is this after having had the system on for a while? It's possible the unit is thermal throttling when it gets hot inside, and if it's not got decent airflow or it's a bit dusty or you live in a very hot place, this can make it more likely for the hardware to hit a performance wall and start slowing down.
Depending on what game you're playing, the timing could be related to your Internet Provider slowing things down on your end, or it being a time of night that a lot of people on your network are streaming/gaming/etc. For example, if you're in an apartment complex and everyone gets the same Internet in the building, then there's a lot more people jumping online at a particular time. Network shouldn't interfere with FPS, but I'm also not sure if you're simply seeing slowdowns or you actually have some sort of FPS counter onscreen that's showing you the framerate changes.
Either way, a Ferrite Core wouldn't do a great deal to help with voltage issues. It could help if the console is on WiFi and there's something interfering with the signal. Try it on either end to see if it works better close to where power plugs in or where the plug connects to the wall.
The best way to get clean stable power when you can't control what's in your wiring is to get a Uninterruptible Power Supply (UPS). They have a battery that's there to keep power going for a while when the power goes out where you live, but they also monitor the flow of current and make it more stable to devices you plug into it. You also get the added protection that if a major surge came through the wall, the UPS would let the battery take the hit and protect your equipment from the surge.
This is a TON of information I know...but I hope it helps you!
@@trentonbennettVO Hello. Thanks for your reply. About network problem, I'm sure that's not it. Because this also happens when my console is offline. And about excessive about of playing, I ruled this one out too. That leaves me with two possible reasons: 1-electricity issue which can be solved with what you proposed.2- or maybe it's some signal that keeps interfering with my console during the day, and it's gone at late night, which I'm not sure how to solve it. Thanks again for your constructive reply, Trenton.
My new boat sonar came with one but was slack on why, how and where to install it. Thank a lot hopefully it will reduce some of the visual "trash" on my fish finder .
Glad to hear it!
Trenton, I am running a power cord to a Garmin Fish Finder head unit, I have loom covering the power cord for more protection. Can i clamp the Ferrite Core over the plastic loom, which makes it tighter, or this will not work as well not being direct on the cord itself? Thx
Hi Kevin! As long as the cord passes through the core, the loom running along with it won't be a problem at all. Hope this helps! :)
Hi great video Thank you.
I am by no means familiar with emi rfi noise, so I got a question.
I am using ferrite cores to supress noise on my pc quipment. From your video I understand I should be placing them near the ports of my pc.
Am I correct in assuming that?
I have a few cores around my power supply, usb, dvi and hdmi cables
Hi Roku! I'm glad this video helps you. That is one way to test, yes. Basically if you're having an electrical interference problem, a Ferrite Core can help you either troubleshoot or eliminate the problem because it shields the device and can block the bad signal...so if a USB device is getting interference from within the PC then stopping it before it goes down the wire might help. However, if the device is getting the interference from the surrounding air, you could also put one on the end too.
I'll explain a bit. :)
If you look at a wired XBox 360 controller, it's got a Ferrite Core built-in, near the controller, just to make sure the controller isn't getting problems from electrical interference. When my friend Veleka (the person this video was for) was having a problem with her USB mic, I suggested she put the core near the mic because that was more likely where the interference was being picked up. These would be times when it seems most likely that the interference isn't coming from the PC and is directly affecting the device connected to the PC.
There was a time though when I had the front-panel audio of a computer creating noise in any headset that I plugged into the front-panel audio jacks. I put the ferrite core on the plug-end of the headset, the end that went into the computer front-panel headset jacks, because I wanted to stop the noise. I eventually realized that the front-panel audio wire inside the case that connected the motherboard to the front panel was getting the noise from something on the motherboard generating interference inside the case. I put a ferrite core on the end just before where it connected to the front-panel. When that didn't help, I replaced the internal audio cable and all was well.
I realize that's a lot of typing! But I hope it helps you. This gets a bit technical but also explains the nature of what causes electrical interference:

Hi Trent, I replaced may tail lights with LEDs now my reverse cam started having noise in the video everytime the brakes are engaged/brake lights are on..
Where would it be ideal to place the core to remove the video noise?..
I am still currently waiting on the core I ordered online to arrive..
I would place it as close to where the camera feeds into the head unit as possible and also make sure the camera and tail lights are both properly grounded / the grounding wire hasn't come loose. Hope this helps you!
Hey mate Josh from over in Australia great video. I also wanted to ask you would something like that help in a car situation not so much for stereo more so with my ngauge and aftermarket tuning software etc on a basis that there are so many cables in and around the car ?.

Hi! RUclips (or maybe Google?) periodically dumps my comment notifications into a different category and I don't always catch my comments - sorry for the delay. I'm glad to hear you're both working together to solve the problem! There are some good suggestions in this document from "Ham Radio University" that might apply to you. hamradiouniversity.org/wp-content/uploads/2019/01/RFI-hamshack-20190106.pdf Most computer equipment has decent shielding on the cables and such, but it's not guaranteed against unusual signals like this, so ferrite might be a good start...but you may also find you need some other shielding solutions or a look at where his antenna is located and how it's oriented. I hope this helps you and I'll be the first to admit this is beyond my own area of expertise! :) Best of luck though.
Are ferrite chokes and cores the same thing, and I assume you can put ferrite cores over braided cables?
Hi Kinang Eagle! Yes, they are the same thing, called different names (even sometimes called a 'ferrite bead') and yes, you can put them over braided cables - I did so in my VO studio to kill a faint hum in my studio monitors (speakers). Hope this helps you!
G'day from Australia, Do you think one of these might help improve the signal I get on my AM radio in the Chevy? The radio stations Iisten to are about 150klm away and although the signal is okay when driving, it goes all screamy when I put my foot on the brake pedal and sometimes when I use the indicators. I have a couple of them here and was thinking of putting my antenna cable through one two times.
if you put these in series would it increase a voltage output or quality? If I get a hum in a audio amp where would i put the ferrite? Thanks
I have a HyperX Cloud II headset and I use the P3 3.5mm input, but I have interference, can I use the ferrite core in the cable or not?
will this protect electronics from HF welding equipment?
Hi, i want to use some ferrite chockes on signal wires of a cnc machine. As they have a certain impendance at a certain frequency, other than fitting tightly on the wire, the bigger impendance would mean more efficiency ?
Thank you.
Hi Ionut Popa! I'm not quite sure I follow the question, but I think the gist of it is that if you have a larger core that the cable can pass through more than once, this would more efficiently battle any stray interference. I hope this helps you!
I recently bought Asus ROG Strix laptop and it keep having this annoying hissing noise when i plug it in and no noise when its on battery. I researched internet about it and find out its a common problem called coil whine with this particular series of laptops. So, i wanted to know is it possible this solution will fix this problem or should i just return the laptop and buy some other one?
Yikes! Is the hissing noise only in headphones or does it come through the laptop speakers as well? If this is coil whine, that's difficult because it means there's something physically wrong inside the hardware--one or more motherboard components are generating interference. If this problem only seems to happen when you use the headphone jack, then try this: 1) if you're using a headset, see if the hiss goes away when the mic is muted or not plugged in at all; 2) If you're just using headphones, try a different pair; 3) With only a pair of headphones (no mic plugged in), see if the hiss gets louder or softer when you raise or lower the volume--specifically, play a video where the Windows system volume is low and you use the video player to raise the sound, then try lowering the video player's sound and using the Windows system volume higher/lower to see if the hiss gets louder with the system volume or with the player's volume. I do love me some ASUS hardware, but their support can be hit and miss. If this is a recent purchase, definitely reach out to them in the event you need to replace the laptop--the sooner you get a ticket in the system, the better negotiating power you have. Let me know how this goes and what you observe (my questions here)!
@@trentonbennett4864 Thanks for replying. It doesn't come from speaker or Headphone but from somewhere under the keyboard. I ran following solution i found on a forum-
reg add HKLM\System\CurrentConsoleSet\Processor /v Capabilities /t REG_DWORD /d 0x0007e066
on command prompt and it somehow made it go away. Now very rarely it makes that noise abd even if it does its for a second or two.
I have no idea what registry i added and what it does. Please let me know i didnt do anything wrong.
@@lonelysoulshivin8256 interesting - well, first off don't panic. You haven't done anything "wrong" and you'll probably be just fine. I read up on your registry key solution. Long story short, a processor is also a device with electricity running through it--and the things that manage that electricity can be very complex. Today's processors--especially in laptops--are much smarter about not draining all the juice and running at full power all the time. So what they do is ramp up the processing power on demand and then idle it down when you're not doing anything particularly intense. From what I can tell, the conditions created by one specific "idle state" (of many) were creating just the right circumstances for electrical noise. All you've done with that registry key is told it "don't use that one", and the system can work around it. Short story long, this explanation "It not really the cpu that whines but rather a coil on an inductor on the motherboard near the cpu voltage regulators" from superuser.com/questions/121883/any-way-to-disable-specific-cpu-idle-cx-states . If it were me, I'd see if I could get ASUS to send me a replacement if I'm still in the purchase window, and then maybe my replacement wouldn't do that--but if it did, now I'd know a registry key I could use to fix it. Good luck! Let us know what you decide to do.
I have a camera system in our farm tractor. When ever I turn on the camera the tractor radio looses reception almost completely this is on the FM side not sure of AM. So will these take care of the problem? I am assuming it would go on the camera part of system but exactly where. The power wires or the camera cable itself? Thanks
This may help, but I would also look into all the connections and make sure nothing's shaken loose *and* (most important) that everything's grounded correctly. If this is a camera system that wires into the fuse box that can be one point where things can come loose--I had this happen with a Dashcam because the wiring required me to wrap a wire around one leg of a fuse, then plug the fuse into the box. I hope this helps you!
Hi Trenton,I have Roku Express streaming media player which is powered by micro USB cable,can I use Ferrite on that micro USB cable?
You can, are you experiencing some sort of RF interference with the Roku Express?
Can you use these in car audio? When you get those noises through your speakers. Do you put them on your ground wire, power wire or speaker wires?
hi Trenton, great video on describing what ferrite rings do. i am getting interference from my wood lathe to my webcams i am wondering if these would help if i put them on the wood lathe power cords.
I really need your help and your video gives me some hope. For 5 years since I bought Powerline adapter the box devices to transmit Ethernet UTP signals using the power sockets on the wall and the house electric wires to establish the connection my speakers started to crackle. When I increase or decrease the volume from the speakers to maximum the crackle sound is starting to be heard .
The power wire of the 5.1 speakers is coming from the subwoofer and doesn't have any kind of ferrite core on it. If I attach the ferrite core on the speakers power wire will it help to eliminate this EMI crackling issue?
I hope I can help you! And I apologize for the delay - I've been a bit overrun these last few weeks but I finally have breathing room to look this over. First, let me ask if you could plug the powerline adapter to a different outlet in the room, and even better yet if you happen to know of an outlet that's on a different circuit than the outlet you use for the computer. If it's not a pain to try to do, this might be a good way to separate out the electric flowing into the device you're using from the electric that's being used to piggyback data on your powerline adapter. There's a really interesting article here that goes into some detail. www.cablinginstall.com/home/article/16467315/how-utp-deals-with-interference (1 of 2)
Next, let's talk about the ferrite core. I think it would help you, and yes, I'd be putting it on the speaker's signal wire, though the power wire might also be a place to try. I'm assuming this is a powered subwoofer with its own power adapter. If you can plug even the subwoofer in a different outlet than the powerline adapter, that too is a good idea. But if nothing I've suggested so far helps, take a look at this video about a Balun Core - same principle but with a simple (literal) twist of winding a cord around the choke. ruclips.net/video/JhAPJISUjB8/видео.html
So to recap, I'd try 1) different outlet for the powerline ethernet, preferably on a different circuit; 2) Ferrite core on the audio wire and/or the power line for the subwoofer; 3) Balun style core like the video (and you can read more on Wikipedia to understand it): en.wikipedia.org/wiki/Balun I really hope this helps you! :)
Are they good for power wires on a cb radio mobile unit?
Hello sir my sub woofer making hummmm noise when switch on .do you think if i put ferrite on sub wire my problem should be solve
Hi Naresh! Sorry for the delay - I don't always get my comment notifications for some reason. If it's humming when you power it up, that shouldn't be a problem. I have a pair of subwoofers that always make a brief hum and 'pop' sound on power-up and I've had them for many years. If your subwoofer continues humming once it's on and powered up, then yeah, that might be a bad ground or RF, but it's difficult to troubleshoot that. These ferrite core things are a cheap way to troubleshoot, and if putting one on the power cord doesn't help, you can also buy various kinds of plug-in gadgets that 'filter' the power (look for 'power conditioner' or 'line conditioner', or 'ground line voltage filter'). I once used a device by Ebtech called the 'Hum-X' to keep a computer's grounding issue from making a hum in my headphones. I hope this helps you!
@@trentonbennettVO thank you very much for helping .thank you also for taking your time for me .take care and stay safe 🙏
I'm very curious what your comment is about the speaker cable or signal transmission rca cables?
Also: If you use only one choke should you place them at the end of the cable or in the middle? If you use 2, 3 or 4 chokes where should you place them?
Just one choke at the end where the device is plugged in should be all you need. Hope this helps!
Hi! Do you suggest to put these on EVERY single cable? USB cable, jack instrument, jack microfone, power supply, headphones… thanks a lot!! 🙏🏻🙏🏻
Hi Giovanni! I'm suggesting that if you have a problem with background interference, then you try connecting one at the area where you think there might be a problem. If it doesn't solve the problem, try it on another device. For example, my friend's USB mic seemed to be picking up a hum, so she connected one to the USB cable for the mic. I had a problem with speakers picking up a buzz, so the cable the speakers plugged into was where I tried it. It may not solve the problem but it does help in troubleshooting--and I hope this helps you! :)
I found one lying around and wondered what it was. Now I can start recording better! That aside, I do notice that some charging bricks would charge my phone and I'd feel a sort of vibration that feels like static electricity, but I tried searching online for why it happens but no results from my search. I might try using this on phone's charging cable to see if it does anything.
I'm glad this was helpful to you!
If we replace a type-c charging cable (ferrite core) with a regular type-c cable. Will it still work?
The core doesn't really make a difference as far as sending power down the cable is concerned, so it shouldn't make a difference - it's there for the benefit of reducing electrical noise. Hope this helps!
I fitted drls ( daytime running lights) to my car front grill, now my radio dab signal is terrible
Where should I fit the ferrite core? To the dab areial cable or the drls cable? And how many?
Hi Lucio! I'm not sure how you're wired--for example, if your DRLs end in a 12V cigarette lighter plug or if you're running the wires straight into the fusebox (or, if so, whether it's wired to the fuse box under the hood or inside the car). So I would take a guess that your DAB aerial cable should have one attached, somewhere close to where it plugs into the radio. If you have slack, wrap the wire a time or two around the core like I do in the video, and just one should do it, if that's what's going to fix the problem. If the DRLs mention that they need to be grounded to the vehicle frame, be sure that they are actually grounded onto the bare metal of the car, because that can also be a source of problems like this. Last, if the ferrite cores don't work, and the maker of the DRL doesn't have any suggestions for you, you may need to try a Ground Loop Isolator. I had a car stereo with interference noise where I had to put one on to properly compensate for a bad ground inside the car stereo head unit itself. I hope this helps you! Definitely a) check all your connections, b) talk to the maker, and c) see if anyone else has also run across the problem, in addition to trying this cheap & easy troublshooting step. :)

Hi aGoodShepherd! When I troubleshoot, I only use one. Manufacturers put them on one or both ends, I tend to focus on the point where the wire goes into something (like a computer), so I'd start with one near the point where the device connects. If you have a serious interference problem, there are a lot of other ways to solve it; this is just a great initial troubleshooting step that often takes care of minor problems. It's a way to determine whether the problem is RF interference as opposed to a problem with grounding. Hope this helps you!
I get high pitched Morse code like noise. Home studio. Worse on guitars (DI) but faint on vocals too. My studio is in the same room as my electrical mains in and my PC sits next to the 100A mains in if that makes a difference?

Hi Volvo5turbo! Does the noise sound anything like these? ruclips.net/video/uPYyrS7fc7g/видео.html There are a lot of things that can cause interference, both on the wire and in the air, so the ferrite core/bead/choke/whatever is one way to troubleshoot. It would be awesome if the noises in the video I link to here are what you're dealing with because that would make the problem as simple as "turn off your cellphone when you head into the studio".

Are sum ferrite cores not removable?
Correct! The ones that can be are easy to tell because they'll have a clasp and a seam that you can pry open...but some manufacturers embed them in the wire, and so you'd have to cut the cord open to get to it, and that would expose the wire. Good question! :)
