    What kind of dire straits are you in ???

    Can you post the problem ???

    I'm not real good on PA Systems...but if you post the problem maybe someone else will be able to help...

    Hmmm...

    What kind of PA System is this ??

    Sounds like something is going on with the power supplied, or maybe ( scratches head ) a dead short somewhere...

    Hmmm...

    Thinking again...without knowing the type of PA system you have, and not looking at the diagrams...at a guess, you have a short to ground from one of the Pre Amps of the sound output ( or maybe even the actual sound output )....

    But that's only a guess...

    With out knowing what is actually going on, it could also be a dead short on the input as well...

    Hmmm...If what I think is going on...a long distance call isn't going to help...

    I don't have any type of chat, nor do I want one...no offence...

    Your problem my friend, needs a tech on site, or for you to to take the PA to a tech...

    IMHO...what you have with this system is a burned out component, or maybe a fuse ( you haven't supplied a model # for this PA system so I can check ) or a transistor...

    Or like I said it could be as simple as an input problem, what I would suggest is test the PA with a different input...

    ok, the model number is PEAVEY 300EH, power is 500 watt.
    It says 120 VAC, 60 HZ
    there are 2, 250 amp fuses inside which are good.
    the encased 5 amp fuse is also ok. (i think, it has the white cover on it, but I got it tested)
    thanks,
    Alberto

    Sounds like the power supply to the PA system (whatever make and model it is) may have failed or is in an extreme overload condition due to a failure of another component in the amplifier.

    It is important that you do not allow it to be turned on for long in that condition, because if the power supply is overloaded due to a failed amplifier component, it could also then cause expensive damage to more components.

    There is simply no way we can help diagnose beyond this point as we do not know anything about the actual PA system. It could be one of thousands of different types and be suffering from a failure of any one or more of a hundred different components..
