"LOUD BUZZ" in rear center!!!! (1 Viewer)

[Craig Ball]

Help, I'm going nuts!!! I have a H/K 520 and two Acurus A200x3 amps running Klipsch Legened series speakers. I have a really loud buzz from the rear center, I'm about to throw the whole stereo in the trash!!!! I can put my ear up to all my speaks and can only hear a faint buzz on the front center, but can hear the rear from the couch and it's about 12 feet behind me.

Have you tried using the HK520's internal amps? If there is no buzz, then you probably have some ground loop with the external power amp.
