Michael,
You will NEED to use an external mixer to do what you want, but the PAS does have phantom power for basic hook ups. It also has effects loops, but they are dedictaed to each of the 1st two channels.
You could use a Digitech VR on each channel, patched direct thru the loop, but a small mixer is a cheaper way to go.
The presets won't affect you much because you'll use the EQ from the mixer.
There are no effects available in the PAS. The only digital processors are internal and deal with compression and EQ.
You're gonna love it, though !
