Sure, Frank; the Amp-100 is a power amplifier(not a receiver or integrated amplifier)and has no pre-amp section. Your separate pre/pro boosts the voltage from the source material and sends it to the amplifier for a further increase. The amount of voltage output from the pre/pro is of course controlled by its own level adjustments and there's no need to complicate things by using two level controls.

Enjoy the music, not the equipment.
