[QUOTE="filtor1, post: 2221822, member: 559406"] I give up, so here is my post. I have a little issue with my HT sub. Here is what I have; Yamaha RXV2400; Yamaha 5dsc DVD(I forget the model); 5 Boston Acoustic CR85's; 1 Titanic 15" subwoofer(the kit that PE sells); and what I think the problem is, my Dish network reciever. Here is the background. I bought all the equipment about the same time. Hooked it up in my Apartment in Tampa and everything was fine. The cable guy(TimeWarner) stopped by to hook up the cable and there was a teriible 60Hz tone coming from the sub. I tried adjusting the gain on the amp, but that didn't help. So I unplugged the coax cable form the cable box and the noise went away. Plug it back in and there it is, back again. So that was my solution for a while, but that got annoying. We moved. I hooked everything up again. No issues. The Dish Network guy comes and hooks up the sat. box and majically, the noise comes back. Now I am pissed. I have tried using different outlets for the plate amp. I bought a ground loop isolator from PE and that eliminated the issue, but eliminated a number of channels. I am just about at my wits end and still haven't come up with a reliable solution. Any help will be appreciated. I have been told that it relates to the improper grounding of the sat/cable systems.
