Is it dimmer hum of ground loop? Good explanation at[http://www.audioadvisor.com/store/productdetail.asp?sku=TRIBGG1&product_name=Ground%20Guard%201%20Ground%20Loop%20Eliminator] Turn off dimmed lights. Hum? Unplug cable. Hum? Ground loops (caused by the cable being grounded at a different potential from your electrical cable) can also be at your equipment. Unplug all video RCAs. If there is still hum, use 3 to 2 prong "cheater" plugs from the hardware store to remove grounds from all bu preamp. If the hum is from video you may need cheaters and cable ground isolator on video grounds.
Loud Hum
I recently bought two Brystons 7Bst's to power my Revel Salons. I also have a Bryston 1.7 and I am getting a LOUD hum from ALL speakers (I run the center and rears with a Proceed HPA 3 while I purchase other 7BST's). The Proceed did not make the HUM while I was using it to power the two Salons and center channel, but now that I am using it to power the center and surrounds it is VERY loud. My Revel B 15 ALSO has the HUM (although not so loud).
Any suggtestions?
Thank you!
