When I plug in my receiver a humming noise comes through my speakers. If i turn up the volume the sound will drown it out. The lower the volume the more you can hear the humming noise.
P.S. When I Plug in my woofer it also makes a humming noise.

I have the same problem.

I've got a Pioneer QX-747 quadraphonic that is pristine, with the exception of noise from the front speakers only regardless of the volume setting, or the input setting. How can I resolve this hissing noise?
Is doesn't go up with the volume, and does not seem to be associated with any control or setting. Think of a hiss in the background of the front speakers, the louder the volume goes the more it drowns out the hiss, but it's still there.
Help!?!?!?
