you can go wet/dry/wet or even wet/dry/dry/wet with KPA
you can assign delay + reverb only to the main outs (L and R) in stero and have a dry signal on the monitor out or even 2 dry signals (L and R) to the monitor and direct outs. this is all made by assigning outputs in the output menu. pretty well explained in the advanced manual
cheers
All unbalanced though, I would still need a DI box to get the signal to the converter.
