the machine Audioholic Jan 27, 2013 246 0 18 Oct 9, 2022 #1 I recently noticed my receiver is producing a static sound while powered on. It’s random, and sometimes cuts out for minutes at a time but it keeps coming back. It happens if there’s no audio playing, and you can hear it with audio playing. the sound level of the static is the same volume regardless of what I set the volume to. I’ve seen other threads with people who have a similar issue, but usually one channel. Mine is all 11 channels any ideas what may be causing this?

the machine Audioholic Jan 27, 2013 246 0 18 Oct 9, 2022 #3 No hard reset yet. It’s so odd because when I was typing it was making the noise, now it’s not. It literally comes and goes. Just started this week. Short video of it below - YouTube Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. www.youtube.com

lovinthehd Audioholic Jedi Sep 11, 2012 44,861 0 113 Oakridge, OR Oct 9, 2022 #4 I'd still start with resets to see if any improvement in any case just to eliminate that aspect. Are there new items on your electrical circuits that might be the cause of the noise? Your link takes me to the youtube "shorts" page and don't see anything related to crackles....

Nope, now takes me to a guy drawing on tarmac. I think it's using the "shorts" tab that's the issue, it constantly adds videos. Try posting from another tab in youtube? Not that it will likely make a lot of difference, videos of audio aren't often very good anyways.

Did you add new gear/appliances to your household? Could be something like dimmer switches, motors, etc causing interference....but I'd still try a hard reset first of all.

the machine Audioholic Jan 27, 2013 246 0 18 Oct 9, 2022 #11 Yeah it’s just random cracking noises, not constant static. Just thought hearing what it is may set off an alarm bell for someone if they had heard it before. since I posted, it hasn’t made anymore cracking noises

If the latter it will eventually declare itself, and probably sooner rather than later. Click to expand...

It can still be something that caused it in the house running at the time but either intermittently or it came on and off. That usually would be caused by things that have inverter power supplies and could include dimmers, variable speed motors (example: humidifiers, mixers...etc., and a lot more possibilities).

the machine Audioholic Jan 27, 2013 246 0 18 Oct 10, 2022 #15 Thanks guys, going to try a hard restart. Kids are home from school for a holiday today, and they are watching a movie. It was static when I turned on the movie, then after 20 minutes or so it went away and hasn't come back. Same thing last night. Static for maybe 20 minutes, then it went away for the rest of the time watching SNF

Next time it happens, I suggest you check around and make sure everything else other than the HVAC and non dimmable lights are on/running. Of course, even if it is caused by certain devices or appliances running you can just never turn them on when watching movies or listening to music, but it is one of the important troubleshooting steps. After that you can at least rule out the house power supply is not the cause and move on to the next suspect.

If his AC has running and starting caps, then failing running caps could cause this. This could also apply to refrigerators or anything that has a powerful AC motor. Failing or noisy SCR dimmers usually cause an AC buzz. I think you and I have a feeling this is interference most likely, I know I do.

I think you and I have a feeling this is interference most likely, I know I do. Click to expand... Yep, not just what you said but also harmonics injected into the power line by devices with variable speed inverters. You may recall I mentioned this way back, that one of my portable humidifier was causing buzz from my KEF speakers powered by a Parasound Halo A21 power amp. That was easy to identify as it would cause the buzz when the humidifier was set to one speed, silent in another speed and the phenomena was 100% totally repeatable. It only affected the Halo amp, but not my other amps such the Bryston side by side at the time, that's why I suspected in that case it was a harmonic resonance related issues. That kind of harmonic resonance causing vibration, even power stability issues are not uncommon in manufacturing or other heavy industries, where numerous high power inverter drives are used. I am not sure if this is the issue the OP is experiencing, but a) based on the symptoms he reported, there is a good chance, and b) it is at least one thing that is relatively easy to rule out quickly.

I fix something similar to this by removing and reconnecting a ribbon connector (CN27), on the right of the receiver on model SR4002 or SR4003. The ribbon where it goes through, at the board cut out, split. This was probably a bad connection issue due to aged contacts. i clean the ribbon contacts with a copper brush. Connection contacts are aways a problem and must be rework. UPDATE: I thought this problem had return. It turns out to be that the receiver was perfectly normal. The problem was that both speakers that I was using had the main speaker cone surround edge, decade, or turn into dust. I will have to buy new speakers, because the old speakers were creating static, with low distorted sound. Last edited: Sep 1, 2023
