    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.

    Hey GoldenBoy,

    Had the same problem, different set though and what worked for me was slipping the ground prong. No I didn't cut it off. You just buy one of those 2 prong 1" adaptors, available at Home Depot, usually white in color and slide your ground prong underneath, bypassing it's usage and that's it, plug it back in minus the ground.
    Hope this works for you.;)

    Yep, ground loop problems, although I would check yer interconnects again. Be VERY suspicious of RCA interconnects, as even the ones you might have had may not be making a good connection. If your setup is as simple as you say, it should be fine. You haven't been hooking up the AC-3's to your normal-analgoue RCA inputs have ya? :)


    I'm sure there's something simple that's wrong in there. Get your flashlight and take a good gander at the puppy.

    Jeffery makes a good point as I had forgotten about the cable ground loop eliminator. You can pick one up at Radio Shack for around $10.00 as opposed to $50.00 that Polk Audio wants.

    Problem solved

    I put a two-pronged adapter on my poweramp's plug and plugged it back in - problem solved. :) No more hum in my system from the surround receiver and DirecTV receiver. Thanks again everyone for your help.
