I run a pre/poweramp setup, and am not sure when the poweramp would be outputting its maximum power. On a recent outdoor gig I ran my poweramp maxed (no attenuantion). While sound checking I had to keep turning everything up to get loud enough, and ended up with the EQ and master on the pre almost maxed. However If I turned on the pre's additional graphic EQ, the volume would increase dramatically. I suppose if I were to put my multi-effect pedal in the chain I could push even more signal into the poweramp. That made me curious-- in a pre/power rig, at what point is the poweramp sending its maximum power to the speakers? Is there a point where the pre-amp processing, EQing, effects pedals, etc., do not continue to increase the overall volume? Or, can it be assumed that if there is unused volume, the poweramp is not maxed? Can a poweramp be made to exceed its maximum output if enough preamp signal is sent to it? Just wonderin'...... any thoughts?
