I laughed out loud at gold plated connectors on an optical cable. 🤣
What's wrong with it?
@@tf2scoutpunch175 Toslink is optical fiber, gold plating is for corrosion resistant electrical connections, just nothing to do with each other. It's like buying an orange at the grocery store advertising that it's high definition 4k.
@@tf2scoutpunch175 Welcome!
@@om617yota8 Nutshell
@@om617yota8 Gold cables could theoretically provide a better electrical connection 'if' the gold plate was thick enough, as it is a softer metal than copper and thus the gold 'could' create a snugger fit into the connection. Note, I don't generally bother using gold connections for anything. I do not think the human ear can tell the difference between gold and copper connections alone.

It was the OS/2 of Microsoft.
There’s an advantage to using fibre optic that went unsung here; the ability to entirely sidestep ground loop problems regardless of where things are plugged! This saved me a great deal of headaches when it was possible
Exactly, that's the real reason to use optical. It's also why the MIDI standard uses optoisolators for every connection, which are functionally the same as TOSLINK just without the cable: an LED and a photodiode (usually right next to each other in a single chip), which are electrically isolated from each other and allow the signal to pass from device to device without any electrical connection.
This! I also used Toslink to avoid hum caused by ground loop.
Yes, it's why I use them.
Hey guys, 10:58
@@well_as_an_expert_id_say ground loops are a rather more specific problem than general interference, and one that is so easy to fall foul of (and in turn providing a specific use case) that it definitely warrants pointing out
MIDI was invented in 1983 as well! A rare case of an entire industry deciding there needs to be a single standard, and then making a single standard and sticking to it.
MIDI was not a single standard until General MIDI was introduced in 1987
Audio is also shockingly computational un-intensive so it has basically been a solved problem since the 80s.
@@fredroberts8275 music note data is absolutely not a solved problem, midi is just way too intrenched, that's why MIDI 2.0 and MPE is a thing, and even that isn't perfect and doesn't cover everything

Yep, amazing that TOSLINK and S/PDIF are still being used. Even more amazing is that the original MIDI standard from 1982 is still actively used on new musical devices. RCA connectors are still used after being invented around 1937 to connect phonographs to RCA radios. But to me the grand champion longest-running interface is the phone plug (or jack), still used on electric instruments, headphones, mixing consoles, etc., which descends from a telephone switchboard jack first used around 1877.
As I recently discovered, having to replace the cable on my radar detector, it too uses a phone cable.
i think it might just be audio, like most audio connectors have remained unchanged and almost all unchanged connectors are audio
The design of the phone plug/jack seems to be perfect. And as aforementioned, established for over a century now. It gives just the right amount of electrical contact & it is sturdy. Sturdiness is key here. It actually resembles a design in biology/nature for millions of years, such as what equipment is used for sex between the 2 genders for many creatures, heh. Apple created an uproar when they removed the phone jack from their smartphones. If it ain't broke, don't fix it.
yeah aux cables rule. 3.5m jack is the champion, no other connection can top that.
something something
ground loops

Fun fact! I ran across a forum thread where someone was having a ground loop issue with a coax S/PDIF connection, and when someone suggested they switch to an optical connection to avoid that, _another_ entirely helpful and not-at-all pretentious person went off about how terrible optical connections are because of bandwidth and clock jitter.

Going too deep into the audiophile community is just hell
Forget clock jitter, it's all about them gravitational waves, bending the light.

He didn't have to call me out so soon in the video🥲
My ancient computer motherboard has quite a noticeable noise floor on the headphone out plugs. It also transmits noise over USB to cheap DAC/Amps I've used in the past. Sending TOSLINK to cheap DACs removed all noise floor. This was a useful fix that served me well for many years, and an example of using optical signal to electrically isolate components.
Another useful "feature" of using a motherboard digital audio out is that you can keep the outputs set as default without them being auto disabled (windows) or having to deal with changing output devices (alsa headaches...).
Not to mention that GPU coil whine will make speakers would horrible unless you're on TOSlink. I had the noisiest 1080 and it drove me to switch to fibre for my desktop audio, I'll probably never go back to traditional cables for my desktop speakers
I have a cheap, nasty external USB soundcard that clicks the speakers loudly when it turns on, indicating a ground loop. But I bought it for the toslink out, which lets me use a better DAC of my choice essentially isolated from the problem.
That said, I'm still using fairly old hardware for digital audio. Good DACs these days can actually perform better over USB (typically better jitter control plus support for higher-bandwidth formats). Ground loops are nasty but should be solved by the receiving device going forward.
@@WildTangler The cap noise from high end GPU's is insane is it not? My 1080 was(is, still have it, on the shelf) ntb but my 3080ti is insane when it loads up.
Yeah and my SMSL dac won't use it's 192khz sample rate with a USB. Unless I use an optic cable, it's maxes out at 96khz.

@@ZGryphon You know, my plastic connectors have often gotten worn to where they start falling out. I don't want gold but since the nub is so small metal connectors could be better.
@@SetitesTechAdventures Huh. OK, fair enough. I didn't think of TOSLink as being the kind of things that get unplugged and plugged back in a lot. In any application I've used them in, they get plugged in and stay that way until I move to another house. :)
the gold plating counters the corrosion and rust buildup which otherwise might make using the connector difficult or dangerous.
My old Sony 5.1 surround sound system (circa 2004) makes use of TOSLINK, and it connects to my Chinesium SMART TV (circa 2020) without any issues and provides excellent sound quality. This video did a perfect job of explaining what was going on behind the scenes, and it makes me happy that old standards like these are still applicable and seamlessly integrate with today's technology.
It’s great to see a homie with a similar setup to me. Mid naughties Yamaha surround sound system with a Kogan smart TV bought in 2019.
I have both optical and SPDIF connections that can do 5.1 on my old receiver, so no need for optical but maybe devices only have optical.
@@abc123fhdi S/PDIF multi-channel is always compressed (lossy), Toslink can pass 8 channels of uncompressed 24-bit/48kHz.
Multichannel *recording and production* will bear specific limitations if compressed data is being implemented at the get-go.
Audiofiles: We need an optical cable to avoid electrical noise.
Also audiofiles: We need to use noisy vinyl records from 30 years ago.
B-but it's WARM noise!
Audiophiles think turntables having convenient and nice features like auto stop and start will hinder the sound quality.
They just love soaking in snake oil. I love records, but audiophiles are the worst.
But if it's gold plated I can definitely hear the difference with $1000 cables.
Records do have better potential quality than any digital format, but still manage to suck because there's so many more sources of interference. Dust, static, wear on the record, wear on the needle, etc, it all ads up to terrible audio quality unless you manage to get everything exactly right (which is virtually impossible)
I must say though, you get better music putting a Frisbee on a turntable than you do from putting one in a CD player.

While I predicted that Blu-Ray would win (if nothing more than it was included in the PS3), the one thing HD-DVD did that I wish Blu-Ray adopted was being Region Free. Buy a disk in China and it'll work on a player in Europe, Africa or America. Doesn't matter. Blu-Ray still has regions though it's way better than DVD. DVD had 8 regions but Blu-Ray has 3. You essentially have America and Eastern Asia (Minus China), Europe and Africa (including Australia and New Zealand) and finally Africa and western Asia, along with China.
It was great for Mini disc recording, since you got an automatic sync and autostart of the recording as soon as you pressed play on your cd-player (after toggling the rec switch on the Mini-disc-player, to ready the Mini-disc for the incoming digital signal). Also all the songs names and track number automatically got transferred as well! Really neat!
At least on the home MD decks, copying the track titles required a separate cable, though. (Sony Control A II, which is basically Sony infrared remote commands, but over cable instead of infrared light.) I know some portable units also required a special cable, though others have said that some models could do it over TOSLink alone.

Still have a couple of Minidisc portables that support this. And if I remember correctly, it was referred to as an, "optical miniplug" in the documentation for the Sony MZ-1 (first MD on the market).
In some sound cards, that is the case but one of the outputs is also miniToslink (I think Xonar had this predominantly).
I had a Mac book pro from 2010 that had this. I didn't know until I installed Linux and couldn't figure out why my headphone jack lit up.
I like how optical also has a role in AC/DC electronics by means of being optocouplers. Isolating two sides of an electronic circuit avoiding stuff like ground loops in things like regulated power supplies.
You can get toslink multi-input selectors and they're 100% mechanical, you just rotate a dial that changes which hole the light goes through.

Do you think that’ll work on my computer?
It DOES avoid ground loops, which are an issue..... sometimes.
as he mentioned implicitly at 11:46
When your monitor isn't properly grounded so it sends voltage through the DVI cable into the case.
I should have brought this up and investigated the issue a little further. The RF interference issue was what I focused on and admittedly I glossed over the potential for ground loops to form. Still, if we're simply talking about which format transmits the _data_ better, there's no difference at all. In fact, as I alluded to, some people think the increased clock jitter from TOSLINK means it can sound worse because... reasons? I guess?
@@TechnologyConnections but excess jitter would have the exact same effect as you pointed out with coax cables picking up em interference. the signal would be transmitted fine until the jitter exceeds the allowed amount, then it would break completely.
Nathan Sketch That assumes the signal is being buffered or dejittered. Historically, this wasn't always the case.

Apple adopted Toslink starting on on the PowerMac G5 in 2003, up through the Mac Pro, until 2012. Also mini-Toslink, on the PowerBook G4 in 2005, and it remained in the MacBook Pro line until mid 2015. As well as the original MacBook line from 2005 to 2010. At the time I thought for sure they were going to release an iPod with some kind of Toslink/optical audio based headphones (for just $199 lol).
What Alex described happening with a combo port happened on my 2009 MacBook; the LED got bumped by a headphone plug, and TOSLink got stuck on perpetually. I never had audio come out the speakers ever again 😔
Also in the AppleTV!
I noticed this when I had linux on my work laptop (the LED was always on)
@@dantehicks1979 That happened to my wife's macbook back in the day. There's a little switch in the port, like on the door of your refrigerator for the light, which gets stuck. I was able to get it unstuck with a toothpick to restore audio. Who needs the genius bar when you have toothpicks?
The fact that the optical connection completely electrically isolates the two connected devices is no joke! At some point I had really irritating problems with connecting some audio devices, there was a clear "hum" that was some kind of ground loop interference. I tested a lot with different grounding settings, and when I finally was able to use a toslink cable, the interference was eliminated. So I would say that in some "bad" grounding related setups the optical connection's electrical insulation property can be a saver!

Don't forget about those fiber optic trees everyone had in the 90s.
I assumed the keying of the TOSLINK cable was to keep things that aren't a TOSLINK cable from being plugged in.
Those fiber-optic trees were cool shit, man.
I've been using Toslink to connect my living room PC to my surround sound receiver for years. The advantage is that it is just one cable going to the receiver, which drives a bunch of speakers that I already have set up
11:17 - Another advantage of TOSlink is it eliminates ground-voltage interference. If you have two devices connected that have slightly different ground-voltages for some reason, that difference will bleed through a copper cable and potentially interfere with anything else connected to the same grounding circuits inside each device. That won't happen with TOSlink.
It's also immune to coil whine from the system. I've been using TOSlink for my desktop speakers for years, no matter how whiny your parts get, you'll never hear it go through the fibre
you can also get optical cables that are only 2.2mm thick and 50ft long for or only $12
Sadly most audio-interference in modern computers are inside the computer, like the powerconsumption and crappy grounding of the USB and the memory-bus bleeding into the audio-amplifier. When I move my mouse around I get audio noice.....there is no skill in engineering nowadays!

ground loops?
was about to comment about that but now i just need to agree
@@Half_Finis when two pieces of electronics have ground planes, which should be at 0v, chances are they are actually different voltages. When you connect two grounded devices together with a grounded cable (rca for instance) and their grounds are at different voltages you get current flow which means noise in sensitive audio equipment. Wikipedia has better explanations.
I'm surprised that I've never experienced a ground loop before, especially with my crazy audio setup.

Mini TOSLink is incredibly common. Even my $20 RCA in/out audio interfaces have optical outs in the 3.5mm jacks, as do 3/5 of my laptops. Every TOSlink cable I ever bought came with a little clear lightpipe adapter that fits on to make it a 3.5mm form factor.
Always loved having Optical In/Out as part of an audio setup just to make use of extra connectors, or hack together setups where there might not be many other options. Really, really useful to have a TOSLINK In and Out on a PC sound card. Great for having audio output both over Optical and HDMI on certain systems.
Toslink is a godsend for connecting certain types of consumer audio equipment together to avoid ground loops.
Toslink would be nice to connect my N3DS to my PC when I'm streaming gameplay from the N3DS online, as I need a 3.5mm audio cable going from the headphone out port of the N3DS to the mic in port on my case's front panel to capture audio whilst gameplay video is pumped over WiFi to my PC via the streaming homebrew I have on the N3DS (since there's just about no hardware capture cards made for it nowadays after KatsuKitty closed shop back in like 2016), and to prevent a mid-stream game loss because of the drain on the battery I need to keep the N3DS charging from a USB charger cable.
The problem is; if I have the N3DS plugged in to the USB ports on my PC to keep it charged, that introduces audible noise on the stream and recording due to a ground loop issue between the USB ports and the front panel 3.5mm audio ports as the grounds of USB and audio ports are connected via the circuitry of the N3DS itself.
Current solution is to have the N3DS charger cable running off a 60W 5-port tablet/phone charger stand as though the charger stand and PC share a Mains Ground, for whatever reason that doesn't induce a loop through the N3DS unlike if I was charging the N3DS through the PC itself.
Nice video, thank you for it😀 Ground Loop could be an issue creating hum, which can be avoided with Toslink. With my band we use Toslink cable to connect 16 Channel musical AD converters to our digital audio workstation and back to DA converters. We use a high quality 4 times Toslink cable, but of course with much higher bandwidth as SPDIF. With this we could eliminate him from ground loops, we had before using copper cable
Somebody: How do CDs wo-
Me: DESTRUCTIVE INTERFERENCE
If the very, very, extremely slight chance somebody I knows asks that question, I will be sure to blurt that out.
Finally! An example of destructive wave interference to add in Physics 101 besides noise cancellation headphones.
Great video ! I enjoyed watching this instructive video on TOSLINK. Thank you for posting !
The only advantage I can think of for optical vs wired digital cables is that the bandwidth of standard RCA cables did not handle the multiple channel multiplexed optical signals and it would be tempting to use an audio RCA cable in a SPDIF port. Maybe the plan was to have multiple high frequency channels on optical toslink. I am sure that the optical cable was a marketing ploy much like the "gold plated" optical connectors though. I once saw a power strip in Fry's Electronics that said it was "Windows 95 Certified" on the box, obviously at a higher price.. People with more money than brains will buy the most expensive product they can find thinking it must be better. "Monster" cables were just such a marketing ploy.
EDIT: Another poster mentioned "No Ground Loops" as an advantage to optical cables which is certainly a huge advantage in an entertainment system containing a dozen or more electric components.

@14:25 - As a former cable installer...THANK YOU! I worked during the period of time where cable was switching from analog to digital, and I can't tell you how many times I had to give people lectures about digital signal transmission and the worthlessness of paying extra for the "fancy" (ripoff) cables, gold or whatnot.
Now with HDMI 2.1 you actually need a very fancy cable. Oops.
Very informative! Using Toslink from my tv to surround sound.
Holy carp, I thought the glowing 3.5mm jack was to help you find it in the dark or something.
Well, at least it has a use that most mini jacks don't have ;)
I'll just go with most. I once joked about there being no bikinis for men and that it's sexist and was told to look up Zardos. I'm not assuming anything anymore. I can't afford the money for more therapy.
LOL! I've spent enough time trying to poke cables into dim shadowy sockets that this would actually be pretty useful.
@TheMarsBus friendly reminder that this is a no bullying channel!. unless youre an apple fan.
The 3.5mm output jacks on my computers sound card are illuminated as well as color-coded. I'm pretty sure they're not optical but it definitely makes plugging in my 5.1 channel surround sound to the proper jacks while behind my desk a heck of lot easier. Way better than trying to read the faint labels stamped into the metal on most computer equipment.
I looked up Zardos, and while I do have (and have used) a Borat mankini, the screenshot image on the wiki page for that movie was horrendous.
"Handy Dandy Movie Input" really killed me.
I really enjoy your videos sir. Thank you for sharing all your knowledge and interests.
I love your channel!♥️👍 Always teaching me new things. Thank you!😊
The digital junk you used on your voice to demonstrate transmission failure was a really nice touch man.
Just in case, looks like it wasn't just an arbitrary junk but a real signal, distorted somehow during transmission.
Handy Dandy Movie Input lol
That's the only way I'm referring to HDMI anymore XD
Thank you for this! It'll go into my vocabulary right next to Never Twice Same Color!
i prefer Handy Dandy Movie Interface
@Pikgears Interface is the correct word, though. Can't have that
I'm listening to you over Toslink, from my Pc's soundcard to my surround amp. Cool video!
External or internal sound card?
"Handy-dandy Movie Input" It took me like 3 or 4 views to catch that. Great Stuff! I love your humor.
Point of order: Where I've had a choice whether or not to use TOSLINK, the alternative has generally not been S/PDIF, but rather analog RCA or 3.5mm, making TOSLINK the only digital option.
Yes. I also use it because it's the only digital output I have.
Point of odor, Lisa stinks.
Same here, the only digital option as well. The alternative is to buy a USB sound card and connect from PC to sound system via USB. You would think sound systems would USB instead of 3.5mm nowadays anyways, but sadly nope.
"Just pretend its 1985, everyone is doing it anyway" - "One of the Stranger Things about it ...". I see what you did there ;)
interesting how you mention it doesn't matter because it's digital, which made perfect sense and made me wonder what they were thinking, but then you later mention the electrically isolated components so that one device can't short another device. That sounds like a great thing to me. Now I want everything to be TosLink(or optical)
Bought my first toslink cables 3 months ago, love it 🥰
TOSLINK is the ultimate ground loop killer.
While SPDIF signal itself is not affected by interference and current loops, the act alone of connecting two devices via an SPDIF or any other cable that happens to connect grounds together is known to make some devices squeal regardless of any specific input, especially if we're talking about cheap shit like consumer HiFi amplifiers/receivers as opposed to studio equipment.
There's a lot of fibre optic stuff in car entertainment systems, called MOST, because a bit of clear plastic is cheaper than copper and weighs less than copper and i guess resilience to current loops and EMI is nice to have too, i mean you know what happens when you start the engine.
We are Toshiba, we MAKE the future.
HD DVD... That was entirely too funny!
Well, they _did_ make the future, but Blu-ray had capabilities for more adcanced DRM schemes, so it was an obvious pick for movie studios concerned over piracy. Also, Blu-ray being included on the PS3 from the get-go was a big factor in its success. Xbox 360 with its separately sold HD-DVD drive ($199) couldn't quite compete...
They know how to make poor power supples for sure
Thank you. Now I understand why I had to polish my TOSLINK cable before it would work reliably with my Chromecast unit. Being a consumer grade light pipe it was so poorly finished that prior to being repolished it would only work intermittently.
I just love how I can use my mom's 20+ year old pretty high-end stereo with broken cd-player and give it a second life together with my 2020 tv using 30+ year old technology.
My speakers on my 10-year-old TV gave out last year, and I bought a new little speaker for it. The only jack they have in common is a TOSLINK, and it's still working like a charm for me!
I have found TOSLINK advantageous a few times when the audio equipment had a ground loop hum. Using TOSLINK eliminated the problem. It always seemed to happen when I had the equipment temporarily installed somewhere, so I never attempted to troubleshoot the ground loop issue.
I always thought that the best application for TOSLINK would be in car audio. Car audio often has grounding and other interference issues between components. But I'm not aware of any manufactures that used it.
Mercedes introduced a proprietary optical bus in the early/mid 2000s called MOST that carried audio from the head unit and CD changer to a separate amplifier
Other makers used it, not sure who actually created it
It's a nightmare to diagnose, but yes, it delivers data throughout the car, with all devices dealing with audio, even handsfree, using it. It's perfect as long as it's good, but if one device dies and breaks the loop, the whole thing turns silent.
Crutchfield recommends you DON'T update your Volvo stereo (2007 XC90) because they use proprietary optical connections to get the sound around, so that apparently exists. Complicated enough that Crutchfield just don't want to sell you a head unit and speakers so they don't have to deal with the support.
Better than the crappy roadies that just cut the ground wire to stop the hum
Audio Control supports Toslink
Thank you for all your very informative videos.
Love toslink. Still then only standard that lets me connect modern devices that you mentioned (TV, Streaming box, Consoles) to my old school stereo amps.
Just before the turn of the last century, I was working with some fairly advanced Toshiba Programmable Logic Controllers. (PLCs) For the industrial process at hand, we used the very same Toslink optical fiber cables and connectors as are used for audio, to connect many PLCs and computers via Toslink ethernet switches. each ethernet port used a pair of fiber optic cables - transmit and receive. It seems to me that we could have about a 300 meter run between switches, and maintained 100 mpbs speeds with 20 ports per switch. It compared very favorably with cat-5 cable, with fewer cables between stations. The speeds were likely limited only by the hardware in use at the time.
In an environment of large industrial drives with power transients and harmonic distortions, optical fiber for ethernet was good stuff.
There's a benefit to optical cables over copper - you don't get ground loops.
TOSlink is essentially a stretched opto isolator. So all your audio stuff is electrically isolated. Not much difference for digital signals but if you have a mix of analogue and digital it might be helpful.
Also LEDs, photodiodes and plastic fibre optic cables are all pretty cheap. Add in the fact it seems like an open standard with no licensing fees and I can see why it took off.
You’re exactly right!
Some very high end bench multimeters (like 7.5 and 8.5 digit units) use internal fiber-optic optocouplers to keep the clean analog and ADC circuits completely galvanically isolated from the dirty digital circuits, and those optocouplers are in essence nothing more than TOSLink modules, but which accept the bare fiber instead of the connector.
This dude is one real hepcat! Love his videos. Up there with the great Techmoan.
I had a PCMCIA card Soundblaster Audigy that had the hybrid optical and analog headphone jack that doubled as a mini-Toslink jack as well. That was a really sweet feature that I utilized.
"It's pretty impressive that a digital standard introduced in 1983 is still quite common in consumer A/V equipment" MIDI's that old too. The classics just don't quit.
just like the koss porta pro headphones - the 1984 design still sells today
Those Koss headphones are speeding up my bald spot
At least those big DIN connectors are going out of style.
MIDI at least has a new version out now-although I don’t think it’s very widely supported as yet.
"Handy Dandy Movie Interface" is my new favorite description. Right up there with "People Can't Memorize Computer Industry Acronyms".

Cool Coconut Tele Vision
I prefer Horizontal Door Media Interface. Because it came with an aspect ratio that is way too wide from it looking like a door on its side. It can also be thought of Horizontal Door TV.
Hartmut W Sager And PBCAK
I have a sampler from the late 80s that has these. It's a Roland S-770...and it came with a CRT, expansion cards, remote keypad, digitizer tablet, external HDD and CD-ROM, and MKB keyboard. It samples at crazy clarity and does all this wild manipulation with super high quality with no aliasing. It can just pipe into a digital mixer. It's wild for the 80s. I imagine it was expensive (it was honestly kind of pricy when I bought it 5 years ago). It has some cool and interesting features and is also neat looking.
This video was enlightening. Thank you!
