Post Subject: That is strange: noise.Posted by Romy the Cat on: 9/23/2013

I made the 543^rd remodeling on the Opera room and move the video playback equipment to the new, I hope the last location. As I connected everything into PP2000 as it use to be (not PP2000+) but older not “Plus” version than I have some light MF buzzing from loudspeakers. There is nothing wrong with the PP2000 as I use it for my main system for long time with absolutely silent operation. Now with only DVD player, Dish receiver, preamp and power amp I have noise. All grounds are lifted and I wonder where the loop is coming from. I will look into it further but it is kind of strange.
