[QUOTE="Jack Arnott, post: 8289, member: 304"] Hello All, I have a festival where I am running the entire system off of one twenty amp circuit. And it is GFI protected. Not ideal, but never a problem before. But this weekend I threw the GFI four times. Not the circuit breaker, just the GFI. It is also the first time I have used the Powersoft amp at this event. I have a four channel amp, with three monitors mixes, and mid/highs, and a two channel QSC for the lows. One time, the performer moved the mic for the uke. I did not see what happened, but there was low midrange feedback. By the time I looked up, the mic was back in position, but the PA was off. Two other times it was while not much was going on, but there was a harp solo. And the harp was quite loud in one monitor. And the other time, there was a lot going on, including a harp. Seems to me like all scenarios for power limiting. So, the power limiting has to be tripping the GFI. Does this seem right? Is is sluffing off power somehow, that the sensor sees less power on the neutral than the hot? Is it sluffing it to ground? Regards, Jack [/QUOTE]
