this is a commercial installation in a bar.so, with all components hooked up for over several years, there were no probs. now there is an amazingly loud humming.Tried plugging everything to diff plugs from other circuits and no resolution.But, when i disconnect the power to the satellite top boxes, the hum amplifies ten fold!i've also unplugged the rca's but no difference. only when i unplug the power to the sattelite box the increase in hum hits.its a real mess trying to unplug every component one by one. anyone with any other ideas.

Dale, how about trying a cheater plug on th sat's?

Or ground the case of the sat box to the outlet?

well i tried the cheater earlier and no results, but next i'll try grounding the sat box. the electrical panel is right near by and all the plugs are actually isolated ground plugs.
