    Humming Noise

    I just got a new HD set top box from Dish Network and I now have humming issues from my Monster and Rotel power amps.When I turn the volume down its noticable from 20ft away. Any Ideas on what it might be before I diconnect all my wiring and rewire everything.



    Please any suggestions

    Are you saying that the amps themselves are humming? Or do you mean there is a humming sound coming from your speakers?

    How do you have the HD receiver connected?

      If it's humming from the speakers, it's probably a ground loop. You can confirm this by disconnecting the satellite input from the box. If the hum stops, it's a ground loop caused by improper grounding of the dish. If the hum doesn't stop, the issue lies elsewhere.

          I found the problem it was a cut interconnect. When I was snipping the tie straps I cut the interconnect that connects the center channel from amp to preamp. My balanced interconnects are very thin so it was cut easily.
