The Buzz was through all the speakers when it was occurring, and specifically when I put my center RCA into the ADA1250 any channel. when I was trying as suggested to just swap the RCAs to different channels, without swapping the speaker wires it would make the hum softer but not gone. In doing so I moved my amp. out of the rack and noticed that while the RCA was stretched the hum would almost disappear.
Thanks again for suggesting to isolate everything.
Socketman saved me a lot of trouble with mention of his 60s building wiring troubles.
That got my thinking about EMI/RFI. Figured already have a power conditioner. Time to clean up and put all the equipment through
it's designated outlets and get it as isolated as possible.
Even took the extra steps to make sure the inputs HDMI, RCA, digital, and tos were all separated.
Wow thank you guys those simple steps solved all my EMI/RFI troubles. It's now silent:}:}:}
Thank you again:}
