Looking for some help: When I power up my Promedia 2.1 system, I get a low buzz/hum from the sub. Even when there is no cables connected to it. There is a radio/tv tower about 1/2 mile away from my house - not sure this would affect it but if you listen closely you can actually hear some faint radio/broadcast voice in the hum background. Any insight would be greatly appreciated, thanks. Darren.
