Hi, I'm using a Denon AVR-484 receiver connected to my TV via optical cable.
While the humming has been there for quite some time it's recently started to annoy me quite a bit and was wondering if anyone would be able to help me out.
The humming comes from the speakers (not the receiver itself). Humming increases / decreases when I adjust volume, and goes away for some of the input settings(unfortunately not for the input I use it for). I've tried disconnecting all audio inputs so that just the speakers and the power cable are connected, that didn't eliminate the buzzing.
Also tried connecting the receiver to different power outlets to make sure there is no ground loop issues. That did not have any effect either.
Any suggestions to what to try next?
I realize it's a fairly old receiver and that I probably should replace it at some point, but I quite like it and would like to keep using it if possible.
