Subwoofer buzz

I have an hsu vtf 2 that has recently began to have a low level buzz when powered on. It seems to auto on with signal but buzzes. I tried disconnecting the sourse cable and the buzz stopped. When I touched the source rca pin going to the sub, the buzz returned. Any ideas on what this could be?? This new finding started suddenly, it worked well before.

Thanks

Sounds like you've got a ground loop. This means that you've either added a component to the system that you didn't have before, have changed how your system / sub is being powered via the AC or connected your system to some type of cable or satellite TV system. If any of those seem familiar, let us know and we can tell you how to find the culprit. Sean
