Faint buzz in speakers
There is a very faint buzz coming from speakers with amp on, but with no music stream playing. Can only be heard with ear right up to drivers. No buzz with amp off or muted. Decent amp & cabling. Is this faint buzz likely still there under music when it’s playing? Numerous noise reduction devices deployed including dedicated circuit, robust grounding, balanced power transformer, various filters. Thoughts?

Russ69...I'm the OP. Thank you for the link to this article from Upscale. It's the best explanation I've read on the topic! I would urge anyone with a similar perceived problem to read this. Any frustration over chasing down a faint noise coming from my speakers has been happily replaced with many more worry-free hours of musical bliss. Thanks to everyone who've shown an interest in helping me solve this riddle. Happy Holidays! |
@jmfinney As @yoyoyaya and @herman have pointed out, there's nothing wrong with the amp. With most speakers and most amps, if you put your ear against the driver you'll hear something and its not unusual that one channel might be quieter or have a different noise floor from the other. |
I recently had a (new) noise suddenly appear in my system. Quite noticeable from the listening position, it did not get louder with the volume. I checked multiple outside and inside lights, as a while ago, my dethatched garage lights were the culprits. I found nothing and upon checking my power conditioner, I found my plug had come loose and was hanging out a bit. I secured it and no more noise. I guess RF was getting in through the exposed prongs. |
