Regarding the 2 posts above;

XenonMan, you are correct, one end is plugged in at the 7005 and the other end is not plugged in at all. I have tried another brand new Monoprice redmere HDMI cable and the result is the same.

The noise heard with the RCAs was quie loud. Not "oh my god turn it off its too loud" loud, but it was WAY to apparent not to ignore.

EEman; correct, the amp and 7005 were both plugged in, speakers hooked up and the 7005 was connected to the amp via RCAs.

I will unhook the XLRs tomorrow or tonight and try the RCAs one at a time and see if that helps.

Thanks for the contiuing responses guys.
