Fixing a Stuttering Digital Volume Knob
HTML-код
- Опубликовано: 19 июн 2024
- If you have an amplifier or other piece of audio equipment with a digital volume knob, but it keeps jittering when you adjust it, more than likely the problem is just the rotary encoder.
It's a simple fix, all you need is a screwdriver, Exacto knife, tweezers, some WD40, and a Q-Tip or two.

Thank you! I never thought I'd be able to fix anything like this, but with your instructions I've done it and it now works perfectly. Saves me buying a new one.
Did this on my fusion marine stereo in my boat. Worked like a charm.
Thank you for taking the time and sharing this knowledge with us

Thanks for showing me what's under the hood on these receivers before I dug into it. Oh for the days of potentiometer based volume knobs I could just spray out with CRC and let dry.
Your voice is so clear and calm, I thought, "He must be Canadian" 🙂You concisely provided all the info I needed to fix the problem on my 10 year old Harmon Kardon AVR-156. The volume would jump from soft to blow-the-doors-off and back with just a small turn of the knob. I was worried it would be an expensive repair or a new amplifier, but your description of the problem fit and I gave it a try. The rotary encoder looked identical to the one in the video. Didn't look particularly dirty, but it obviously was. Paid particular attention to cleaning the contact points on the delicate copper arms. Works like new now! Thanks!
Used your suggestion with my Skyfi boombox for Sirius XM, and that did the trick. Its been on the back porch for years, where I listen to it. Thanks!
Amazingly fantastic video! Brought an Arcam A38 Amp on the ultra-cheap where the volume control did not work when turned quickly, followed your guide and it's now working perfectly! The amount of green crap that came out from the mechanism was scary!
Like some of the others mentioned, the delicate parts are on the PCB, need to be VERY careful cleaning them.
Thanks a bunch for posting! 😊
It worked for me! In addition, I bought the rotary encoder just in order to be prepared in case I need to change it, but so far it’s working smoothly. Thanks for the tutorial!
Digging the Persona music in the back
Worked perfectly. My knob design was reverse, the delicate contacts are on the pcb side. Now works flawlessly. Thanks.
Even though our receiver is pretty different and required much more work to access the volume control, your video made us feel like we could fix it ourselves and lo and behold we did! Thanks!
This video applied to my metronome as well! The wheel to change tempo had identical symptoms and the repair shown worked. It was more challenging bc it's smaller, but the information was 100% effective. If you have this problem with a Tama Rhythm Watch or maybe a Boss Dr. Beat, try this!
Thanks man! Nice short video. Fixed my Pioneer amplifier without needing to replace any parts!
Thank you very much sir, i just did the same exact thing to my faulty Marantz receiver and now the volume knob work flawlessly. Thank you again.
Which receiver do you have? I have a Marantz AVR (SR-7012) with the same issue... - Any tips for me? It's only a year old. - Thanks! :)
i have the same issue with my marantz sr6005. any tips?
my 7012 also has the issue
Hey! THANK YOU ! I just took apart my beloved 20 year old Pioneer Elite receiver to try your fix and my volume pot looked almost exactly like yours and the cleaning and mild lube fixed my problem too. 😁😁😁👍🏻 Thank you again for your efforts and making this video.
funny i seen the same fix done in a lame way on the same AMP but your way you did is the best way and thank you
Thank you, just needed the confidence to pull the volume control knob - was expecting a grub screw somewhere!
Thanks for sharing the info. I have the same issue with an RCA Professional STAV-3880 5.1 receiver. Going to try this fix.
Thank you for taking the time to create this!
Thanks it worked like a charm for my Rotel integrated amp. I used contact cleaner. All the best just subscribed.
Thanks so much! That took me 10-15 minutes and worked perfectly!
Thanks a lot for this help. I managed to fix my Cambridge Audio AXR85.
Thanks! Worked like a charm on my Arcam A85. Needed to remove the front panel, because everything was on one board, otherwise the same procedure. Also i used Electronic Cleaner instead of WD40 since it leaves no residue.
Many thanks for this. I happen to have the exact same model so this was extra easy for me!
Just fixed mine with the great help from your video thanks 😊
that worked! thank you! It didn't really work until I used the WD40 to the contacts.
Thank you! I am having the same issues with the exact amplifier model.
Thanks mate! I have some wireless headphones where the volume knob seems to have the same problem. Will try that soon.
Thank you very very much! I've been having this very same problem with a PureFm radio for about 1,5 years. We had to always use the remote or start fiddling and meanwhile sighing. 😓 I've been searching the internet for quite some time now to find a solution. I will subscribe to your channel. Again thanks! You made my day 😊
Really glad to hear it worked!
FM NOT COMING IN AMPLIFIER
Brilliant! Great simple explanation! I can now fix mine. 👍🏻😁
Thanks bro! Solved the same problem in a Arcam AVR.
Wow! Thank you so much!!! I was about to throw away a great receiver. Back in business
Thank you very much for this video.
Very thorough. I feel confident in fixing my late brothers receiver now. Now if i could figure out why the subwoofer wont stay on when i push in the button. Wont turn on via remote or any buttons on the receiver. Its just ghe front of the woofer. If i hold it in, it stays...lol...cant jam out very well that way though.
Thanks , helped me a lot !!!
Saved me from an £80 repair bill, Thank You
good job ! thanks!
excellent, worked, now i feel better :)
It worked.... thank you
Thanks this is helpful ^^.
Is it possible to solder on a second encoder in parallel with a long lead to for example use on the desktop?
Can also shoot a shot of deoxit if there is access on the potentiometer (pin hole)
thank you so much, worked :)
Thanks man 👍
Helpful
Not sure how it happens that this is exactly ( same receiver) the problem I have and the fix for it, but thanks so much!
excellent
i have cambridge audio azur 540 r the fan is constantly going round and its noisy can you help
What makes a volume control cut out on only one side? Thanks
Thanks, I'm looking forward to trying this. Question: Can I use vinegar or something instead of WD-40?
I would recommend 70 percent Isopropyl alcohol (aka Rubbing Alcohol). Vinegar probably won't help. You can buy a bottle of rubbing alcohol and use a paper towel or buy alcohol pads.
The part is called a rotary encoder
@@andrewsawesome thanks
Wow...You saved my life!Few days ago ,my 551 R started to work only in analog stereo direct...any digital inputs not working????????????Any advice ,and how to fix that?Thank you!
Glad to help! As for the other problem, sorry I'm not familiar with that unit.
You can tell this happens even better if tou continue to move the volume knob left even if it is on mute. If it is flashing -99db or whatever, then that is the same thing as this
started by having the knob not adjusting the sound at all un plug/unplug the ribbon cable it work but now it jiggle like this :S
and its a whole pcb i have to dismantle + the encoder case is literaly soldered :S
talk about a bad day
just before that i modded a PID controller with a relay but the 12v signal ain'T powerfull enought to activate a 12v relay :S
mosfet time
Saved my Outlaw 1050 from the landfill!
Omg haha I got as far as pulling my knob off and realized it was just free spinning on the shaft 😂 no wonder it wasnt working right! 🤦♂️
This is similar to the problem with my TEAC amp but mine happens more when I use the remote, weirdly enough. For example the volume is on minimum, I tap the 'volume up' button on the remote and it keeps on going up until I tap the 'volume down' button, at which point it might stop, or just send the volume back to 0 again. Any ideas what the problem could be? Typically it's just out of warranty ☹️
My initial guess would be that the button on the remote is some how getting stuck. It could also very well be a firmware issue so this simple solution may be irrelevant. If you cover the front of the remote right after pressing it, does the volume stop changing?
If it does stop, the contacts on the remote might need to be cleaned. If you take the remote apart you can clean the contacts for the buttons on PCB using a Q-Tip and some alcohol. To clean the rubber membrane portion of the remote simply push down on one of the areas on the button and gently drag the now exposed black carbon contact across a white sheet of paper.
@@SamCampbell Hi Sam, thanks for your swift response. I don't think that the problem is with the remote... I'm sure I've replicated it with the volume knob on the amp too (although it seems less prone to the problem). I covered the IR transmitter on the remote after tapping the 'volume up' key and the volume kept on increasing on the amp. I might speak to Richer Sounds tomorrow. Maybe it's to do with the hot weather??!?
I've had just over five years flawless use from it so something's gone wrong somewhere 😬
Ive got the same problem with a Topaz SR10, but for the life of me I cant pull off the volume knob.
I have a Cambridge Azur streamer with this problem. Hope this works!
A fine alternative is dipping it into a ultrasonic cleaner filled with isopropyl or ethil alcohol. Cheers
Would deoxit work
My Soundstream vr 346b is doing this
I have this problem with my stereo in my Ford Fiesta SE 2019😐it’s fucking annoying to the point where I have to cut off all attention on the road to actually raise the volume. Obv that’s a problem than can lead to death so I need to fix that shif
I've owned amps and receivers, (with analog/mechanical Volume knobs), going back to a tube Bogen, and I have NEVER had any problems with the volume knobs.
But every single newer Receiver that I've owned with these digital/encoder chipped volume knobs had all stuttered within 2 years of use.
For gawd sakes can't any of these audio receiver maufacturers today not FIX this yet. ?!
Let's face it, these digital/encoder volume knobs are all badly-designed crap, and manufacturers know it, they just want you to go out and buy a new receiver.
Never use wd40 on potentiometers or on any audio. That is not a great contact cleaner. Wd40=water displacement 40

@@SamCampbell its says wd-40 "electrical" not electronic. Electronic is audio and its components electrical is like dc electrical house relays etc.... It wont do harm but safer to use dexoit
Agreed. WD-40 is not meant for electronics cleaning. Sam links to a WD-40 branded electronics cleaner above, which is fine, but that’s not what he said and could confuse most viewers.
