    Default Fed up of ground loops.

    I hear that stupid buzzing from the speakers when the volume is real low or between songs. It is now driving me crazy because I am focusing on it.

    My new mission........get rid of the freakin' buzzing.

    I've read up on this some time ago, but forgot where. Now I'm turning to the forum for assistance....I need tips, gadgets, gizmos...whatever it takes to get rid of this crap!

    Please help!!

    Maybe it's time to start downsizing.

    I've actually stopped now at 9 amplifiers....so no more upsizing. However, there is no intention to downsize at this time.

    Unhook your cable connection first (if you have one); that's the BIGGEST offender on the ground loop hum front...let us know if that helps.

    I had the same issues,although I don't use a cable coax,it's installed very close to the electrical outlet.

    Checked the Dish outside,and no ground wire...had an installer properly ground it,and the ground loop hum is still there,but not near as audible as before.

    Might be worth looking into,if you have CATV hookups anywhere close.
