Speaker buzz

[merwine]

What does it mean if I get a slight buzz out of all of my speakers when my amp is no but my processor is not?

I believe it means you have a ground loop problem. I haven't had to deal with this issue yet so I can't provide you too much info on it. Sorry. But, it really does sound like a ground loop issue to me. I am sure one of members of this forum who are more familiar with this type of problem will tell you what you need to do to fix it. My guess is that a "cheater plug" attached to your amp plug will probably help take care of it.

I played with it a little more and noticed that it also does it while in processor is on and no source material is playing. If i increase the volume in the processor when I get to about 0db on the readout I can hear a clicking with every turn of the nob out of the speakers.

I've seen many of these problems. In most cases it's caused by a ground loop. For instance, most people create a ground loop by having both the DVD player and the TV connected to the amplifier, while the DVD and TV are connected to eachother by SCART.
Also, switched-off equipment can still generate a buzz. Try disconnecting all equipment, only leave one source connected. If the buzz disappears, try connecting all equipment one by one to find the problem.

Sometimes it's simply caused by a bad cable between power amp and processor. This should be easy to check (try different cables).

Good luck,
