    I've got a major problem here people. While playing a game today I heard the worst buzz coming from my HK AVR320. What is really driving me crazy is that this is the second amp that has done this. So now I believe that my circuitry is wrong.
    Here's a list of my equipment:
    Toshiba 55HX70
    Toshiba 3750 dvd
    HK AVR 320
    Samsung LD
    Sony PS2
    Starchoice Satellite
    Velodyne ct100
    NHT 1.5 (front)
    NHT Super Center
    NHT Super One (rear)
    Can anyone suggest a course of action? I don't want to have to switch another AVR 320 for nothing. Do I have a grounding problem somewhere? [​IMG] If I do what do I do next?
    Somebody please help me salvage my hometheater...I really don't feel like disconnecting the entire setup as I just placed the whole thing in a fancy wall unit[​IMG] . Any help would be greatly appreciated.

    First, unplug the PS2 from the receiver, so you know if it is indeed the receiver that is at fault.

    The first thing I did (after cursing like an idiot) was to unplug the PS2, and the dreaded buzz is still there. After some more research I found out that the hum started at the same time as when somebody plugged in a fan somewhere else in the house. Is my 320 going to keep buzzing?

    Does this make sense? I was told by someone (who is a budding electrical engineer) that I probably blew a resistor in the amp. He said that my AVR320 should be plugged into it's own power socket and circuit, instead of sharing a HT power bar with all my other units. Is this true? I did have a Kenwood 510thx before the H/K 320 and it never buzzed. Now whenever I turn on the AVR320 it buzzes like a power line? Should I go out and promptly exchange the 320?

    To Kevin_Hassan.
    Did you received an answer for your AVR320 buzzing problem ?
    If it's true that the AVR must be on a separate AC plug then I think we're a lot to potentially have that buzzing problem because even though you plug it on a separate plug, normally all the plugs in a room (living room for example) are on the same circuit so the end result is the same, at least I assume...

    Thanks for all the help people. With some pointers I managed to track the problem with my hometheater. It was my Zenith hometheater powerbar. The darn thing shortchanged my amp, by not supplying it with enough juice, which caused a blown resistor....hence that terrible buzzing noise.
    So the lesson that I learned from this is to never buy a bargain power bar for a decent hometheater system...[​IMG]
