Help, new amp causing "buzzing" in speakers

I just bought and installed a parasound 5-channel amp in my system. I am now getting a "buzzing" noise from all 5 speakers. there may be a low level hum also but the noise seems to be coming from the midrange/tweeters. I know its the amp cuz I rehooked my old amps(NAD)and the noise went away. the noise does NOT get louder when the volume is increased. with 2-channel music its not that big of a deal but with movies the buzzing from the rear speakers is VERY annoying.

Anyone got any ideas on the cause of this? why isn't it there with my old amps? I don't really want to buy an expensive AC conditioner since I never had this problem before. could the amp be defective?

thanks in advance!!

Try using a cheater plug, most of the time that is the cause of the hum.

Yep, try what Rmml said. I had the same problem and installed a cheater plug and the problem went away. In our new house we don't have the grounding problem, so it's probably the wiring in your house.

If you have a cable TV connection going to your setup, disconnect it to see if the problem goes away. I had this problem with a ground loop and cable.

I've had this same problem with Parasound and Adcom amps, and using a cheater plug(floating the ground) will solve your problem.

Call Tony Pointes at 415-397-7100 as he is the head technician at Parasound and can likely get to the root of the problem.....
