Help,

I recently purchased a demo model Anthem AVM 20 and hooked it up to my system. When it plays for about an hour it starts making a slight screeching noise through the speakers. I know it’s not the amp, Citation 7.1s. I hooked up a NAD L40 to the amp and it didn’t make the same noise. I changed out the speaker cables too, no luck. I knew that was probably not the cause but I’m trying to rule everything out. I made sure none of the cables or interconnects are touching power cords so I’m not getting cross talk. I wouldn’t think I got a bum unit but I guess it’s possible. The only other thing I can think of is the building is really old and the outlet could be bad. Ok at this point I’m shooting in the dark. Help please.

It's not the old outlet or house wiring that's causing your problems.
