    Hi everyone, I am a newbie, hope somebody can help. I have searched for a solution to my problem but nothing mentioned in any thread has worked.
    I recently installed a Vibe Alpha 11 subwoofer to my system which I think is causing the problem. I am getting unacceptable rear speaker humming/buzzing even when the amp's volume is zero. But if the sub is disconnected or turned off the speakers stop the annoying noise.

    I have as follows;
    Toshiba 36zd26p
    Yamaha A492
    Kef Q35's
    Kef Q95c
    Yamaha NS E103 rears

    Any help will be greatly appreciated.

    Could be a ground loop or the cable between amp and sub.

    Try using some AC filter between sub and mains outlet.
    Also try using the same outlet as your amp, i.e. from the same feed.
    Also try changing the cable between amp and sub, perhaps a (better) shielded one.

    thanks for your reply as i am new to this. I have replaced the lead from the amp to sub with a very expensive lead which made no difference at all. I'll try the other things you mentioned aswell, reading through past posts this seems to be quite a regular problem

    thanks
