Thank-you Brianmgrarcom!! Once I put the plugs on to short the RCA inputs on back of amp, The Hum went away!! If I would have read the manual, I could have saved myself alot of time and hassel. To the above parties, My equipment is totally balanced and of the same manufacturer!! Thanks again to all input. Steve
Hum and Buzz on XLR Interconnect
Recently purchased a Balanced interconnect to install between pre-amp and amp. I have the same interconnect in balanced form from my CD player to pre-amp. The new interconnect connecting to amp has now a buzz/hum. When I re-install my RCA interconnect the buzz/hum is gone. Never had this problem before. My house is older and I don't think it is grounded although I use a 3 prong hospital outlet for the power cords. Any way to eliminate or is this particular unshielded interconnect just not compatible with my amp although it works on my CD player. Thanks, Steve
