Something else to consider re: ground loop problems. CATV lines are a common source of ground loops if you have a TV connected to the receiver, and a CATV line going into the TV (or VCR or whatever). I had a ground loop problem related to a CATV line, and for some reason I only heard hum or buzzing through the phono system (probably because it's a lower level signal). The problem was solved by inserting a Jensen isomax transformer before the cable box, cost around $50. www.jensentransformers.com
Hum in Speakers - AMP switched to Phono
Hello,
I have a Denon 5700 A/v Receiver and just purchased an NAD 533 turntable.
When the Denon is switched to Phono I hear a very noticeable hum coming from the speakers.
All my equipment is on a dedicated circuit and I am running everything thru a PANAMAX Line Conditioner.
I have not had a turntable since I was a kid and just got a hold of a bunch of vinyl.
Is the hum supposed to be there ??????
Thanks
Mike
