I think this is the right place to ak this... I've just begun using powered speakers (let's stick with PA mains for now) JBL PRX712's. I've turned them up about halfway so far, for the most part. I'm finding that I'm using unusually high gain settings on the board to reach the same volume as with passive speakers pushed by 400 watt class D amps. Question is, do those "volume" controls on the speaker act as atttenuators? If I turn them all the way up will they be a closer equivalence to a passive speaker - or do I put the amps at risk? I realize there's a 1500 watt power amp in between the board and the speakers, but I'm still wondering: for those who use powered mains, where do you typically set your speaker volume control? Thx!
