Buzzing sound from VR4Sr

Unhook the speakers, do they still buzz? That's what I thought, its not the speakers. The problem is further upstream, it sounds like it is probably a ground loop causing a 60hz hum. Try ground cheaters and see if by "floating" the ground you can get rid of the hum.

Possibly CATV is somewhere in the system (cable box or VCR)?
Unhook cable from system if so.

60 cycle humm coming from your cable TV. As a test try disconnecting you cable TV and see if that does the trick. If your cable is the culprit. Try a jenson transformer group loop isolator -worked for me.

I believe that you new amp has a 3rd prong at the IEC connector which draws addition current. Unfortunately, if your cable is not properly grounded, the 60cycle will make its way through your system and cause the a "buzz" sound in your speakers. I heard cheates plugs will do the trick but they are also considerd a fire hazzard.

Read the Reviews on the Prem 350 the hum is from the amp interacting with the DC on the line.

BTW great combo!*>)

The CJ350, a great amp, btw, is sensitive to grounding issues. When I owned one, I had to put a cheater plug on it which lifted the ground, and that eliminated all the hum or buzzing.
