Hi - Hope someone can offer some help on this issue...

I have a consistant hum while watching broadcast cable TV with all audio components turned off. Only the TV is on. No digital cable box, just direct analog. The hum is coming from my powered sub. When the picture changes on a broadcast, the hum changes in volume/intensity - stange coorelation in my mind.

First, I must say that all of my gear (including the sub) is plugged into a Monster powerbar 1100 conditioner/surge suppressor. I didn't notice this hum at all until I installed the power strip.

My Tv is a Sony 40XBR800. My sub is Atlantic Tech 162pbm. I have the Outlaw 1050 receiver.

Any thoughts on the problem? Anyone suspect a defect in the power strip?

Thanks in advance!
