I have my home theater setup in the basement. Unfortunately, the only outlets reside on the opposite side of the room. Currently, I'm running a standard orange outdoor extension cord across the room. I've plugged a basic computer surge protector into the extension cord and the equipment into the surge protector. Recently, I've been experiencing sporadic buzzing from my speakers. I thought it was my amp, but now I'm noticing that whenever the buzzing occurs, my video distorts as well. I'm pretty sure that there is nothing wrong with my amp or my projector so I'm thinkng this is some kind of power surge or dip. I'm not to familiar with diagnosing electrical problems in a home theater system. I only need about 5 or 6 outlets for my system and I'm not worried about any fancy noise floor lowering or anything like that. What would you recommend I look at? Does this sound like an electric problem? If I plug a Panamax or similar unit into the extension cord instead of directly into the wall outlet, does this compromise performance in any way?
