I am new here and am desperate. I have posted on polkforums and avsforums that I have been using to get assistance and i am still stuck with this parasound dilemma.
I recently brought a used parasound A51 power amp for my home theater. I plugged it in when i first brought it home and made sure all the channels were working. At the time I do not remember there being a buzz/hum from any of the channels.
After getting my room together I go to plug everything in and I have a buzz coming out of channel 5.
Initially i was having a ground loop issue that was due to my coax cable because I had an hdmi cable running from the cable box in a different room to my HT room. However after I unplugged the hdmi cable the hum went away from the other speakers but there was still a buzz coming out of channel 5. I unplugged all the inputs into the back of the amp (so at this point there is just speaker wire and power on the amp) and the buzz was still coming out of channel 5. It doesn't matter what speaker was plugged into it.
I took the amp to a local parasound service center here in KC and they checked it out and said it was OK.. he didn't find any problems with it. however it was still humming out of channel 5 back at my house. i took the amp to a parasound retail store here in the KC area and plugged it in there and while there is still a hum coming out of channel 5 it is way way softer and requires me to have my ear right up on the speaker.
I guess there might be an environment issue that is causing the problem but I am not sure what it is.
