[QUOTE="Evan Kirkendall, post: 146111, member: 5"] Re: JBL VP wedge failure mode I don't know how similar the voltage protection is in the VP series, but in the PRX600 series, if the voltage sags or exceeds by what seems about 10% of what the amp's looking for, the amp goes into "protect" mode. The power and signal lights stay on as you described, but no sound comes out. Took me a bit to figure it out(seems to happen the most on generator gigs), but I've had it happen to one box in the chain and another one won't be affected. Just seems to be a matter of how sensitive that particular box wants to be. Evan [/QUOTE]
