I'm saying 4 as if 1 is off and 10 is full on but actually if you think of a clock It would be about 10 o-clock on the master, not quite up to half, and the pre-amp set just below clipping on the loudest played note as they recommend. Bass full up but as long as I'm not clipping the channel that shouldn't matter. With those settings using the LMII running 300WTS at 8 OHMs the cabinet was folding in the music store. That's why I didn't buy it.
