Help-

Just over the last few weeks I have been getting feed back from my subwoofer when I change channels on my DirectTivo or turn down the volume all the way my receiver (It is a pop, well more like a bump). I currently have a Energy subwoofer hooked up to a Denon 4800. I searched the archives and didn't find anything. Does anyone know why this started happening (I have had this setup for over a year)?

Thanks for your help...

I am trying to help my brother get this thing solved. I have no idea why he is getting the popping noise when he switches inputs. We just tried a cheater plug and that did not help.

Are there any suggestions? Please help.

Off the wall possiblity. Did you recently rearrange things a bit. I had a similar problem when I added a DSS receiver to my system. I pulled everything appart and reorganized all the cables as I hooked stuff back up.

The problem was I inadvertently hooked the sub up to the 6ch sub input rather than the sub preout (teach me not to hook stuff up leaning over the components). This resulted in a thump whenever I turned a component on or off. Although I also had no bass :p)

Double check that the sub is hooked into the sub preout.

Thanks Dustin,

We did and it is properly hooked up. The sub is working, it just has a feedback pop when a channel is changed on the Tivo or when an input is selected. The only thing he has changed is that the cable now runs under the house. I guess we should try a different cable. Maybe that is the issue. Anyone else have any suggestions.

Had the same.
Bought a used AVC-A1SE and same happened with my subwoofer. As I still had the 3802, I double-checked to make sure this is not on the subwoofer side.
It looks like the sub pre-out is damaged.
There seem to be some "mute switch" responsible for keeping the sub quiet. I got this answer from Areadvd.de forum.
I brought my Amp to a Denon service and await their verdict.
