Hello everyone. I was wondering if anyone could give me some help with this problem: I tried to hook up my DirecTV reciever to my Multichannel receiver, but when I do it sends a hum through my stereo setup . Now, this puzzles me because my surround sound system is seperate from my stereo system, the only thing is my SACD player's multichannel is hooked into the surround receiver's 5.1 inputs and the 2-channel outs are hooked to my stereo. That is the only connection between the two systems. My pre-amp, amp, and speakers for my stereo are not connected to the surround reveiver in any way, and the multichannel setup uses it's own speakers. Does anyone know what the problem might be and what I can do to fix it? Thanks in advance for any suggestions.
