Supply Voltage - Testing and monitoring

    I have had sensitive equipment ruined in the past from low voltage (browning) at a gig.

    My question is...What precautions and equipment do you use to test the condition of and monitor the supplied power at a gig?

    Is there a point at which you would refuse to play because of potential damage to your gear?

    I can think of a place here in my town that has horrible outlets that are questionable: but if you refused to play there in 10 minutes there would be another band with their PA setting up to take your spot for the same crap pay. I also have had no problems with the power there. I think that a good electricians tool to check grounding would be cheap enough to throw into a gig bag though.

    If the rest of the band is pulling enough power that it's causing a brown out situation for your gear then breakers should be tripping in the electrical panel.

    If they are not blowing then there is a serious electrical problem. Get a voltage meter and watch it.

    Switch to LED lighting, use class-d amps. You'll have plenty of power available.

    I use a monster pro2500.
    Gives voltage readout and proper ground indication. If voltage goes to high or low it should trip the breaker on it and prevent gear damage. Exceeding 15 amp draw should trip it also. Building breakers should be tripping also if amperage draw is more than the circuit can provide.
