I am updating my system, and last night I got a really bad hum coming through my speakers while connecting the dish coax-cable to the back of the receiver. When I eliminate contact from the Dish receiver, the hum goes away, but the moment I connect the cable, the hum re-appears.
The cable for the speakers and the Dish come through the same "hole in the wall," and I can't isolate or move the DISH cable away from the speaker cables. What have you guys done to eliminate this noise?
I use CROWN pro amps, connected with XLR cables to a Marantz AV7005. I have a ground running to the location, but it doesn't appear to remove the hum.
Thoughts? I've read about a "cheater" plug, but not sure if that will eliminate it.
