Single ended or balanced interconnects? Many amps require shorting pins for the unused balanced inputs when going single ended. I'm not familiar with Pass's requirements but the topic should be addressed in the owner's manual.
Buzz originating from amp...please help ?
I bought a Pass X250 through Audiogon and when hooked up to my system, a hum or buzz is coming out of the tweeters and midrange speakers on both channels. After exhaustive trial and error, I find that the buzz does not exist when the amp is not hooked up to any other component. It is of course connected to the speakers. If I attach a pair of interconnects to the amp (whether or not these interconnects are connected to the preamp), the buzz comes back. Does anybody have any ideas what I should try, or what the problem may be? Thanks for any imput.
