So I have massive feedback in my powered speakers out of my surround surround.
Coming from virgin media.
I can be on my Apple TV through the surround sound, and have feedback unless I disconnect the virgin media from the system. (Either the hdmi from virgin to surround or the coax cable to the virgin).
I have removed all unnecessary plugs etc and stripped the system down to bare minimum, to ensure it’s no power crossover: and I have also swapped the main 360 box for on from the room.
Either way as soon as the coax is connected it introduces feedback that I hear through my powered speakers.
360 / Apple TV >>>> Marantz AVR >>>>> TV/KRK Rokit 8 powers monitors.
Never had this problem with Sky. Could this be a coaxial issue from outside to the house? It’s confusing me, as the speakers are fine with anything else, but not with the virgin?
thanks in advance for any pointers
Sounds like a ground loop issue, could try one of these
