    Unhappy NEED HELP!!!Hum noise from front and rear speakers

    I have Denon AVR3805 and hooked it up with Polkaudio speakers (Monitor 60, monitor 30, CSi1 and PSW12). I just noticed the hum noise coming out from speakers, especially the front and rear speakers. I turn off all other units but the hum noise is still there with AVR3805 on. The hum sound can be heard when I turn on the AVR3805 and turn the volume all the way down to 0. Any suggestion to get rid of this hum noise.

    Are you in the US?

    if you have a grounding plug, Try putting a ground Isolation plug on the AVR.

    What is it all connected to?My first guess is the sub....try a cheater plug and go directly to the wall outlet.Give us a better overview of how your gear is wired and we can better help you.Power conditioner? Cable box?

    One suggestion I was given was to disconnect your cable TV wire. It does indeed give off a hum in some systems. Is this a new problem, or new equipment? Fluorescent lights, wireless phone, and electric motors can do the same thing.
    Good luck let us know how you made out
    Thanks

    Now I am in Thailand with 220 Volt, 50Hz. The power line here doesn't have a seperate ground. I have tried to seperate the power cords from the speaker cables but that didn't help. I have changed the male plug to Hubbell and changed female plug to Wattgate. I have done that because I thought it was the power cord that gave me this hum noise but that didn;t solve the problem. Now my AVR3805 doesn't connect to any other unit becasue I want to isolate the receiver. Yes, the noise is still there!!!! Any idea how can I ground the AVR3805??

    I had a hum into all my speakers when I connected the cable line directly to the Digital Cable box, because technician told me to connect it directly. When the tech left I connected the cable to my Monster Power bar 2100 and then out to my box, BINGO hum gone!
