pmp1680s effects engines routing


I've ordered a PMP1680s for my band, but I'm looking for clarification: Are the internal effects engines routed to one amplifier apiece? Or can I run both fx engines simultaneously to the mains and have the same to the monitor? Or... if I run it in stereo mode, can I use both fx engines on both channels? (ie NOT, one engine for the left and one for the right) It would be useful to have say, a reverb AND a chorus simultaneously, but not if they are coming out of different amplifiers. The online manual is not clear on this. A block diagram like is provided for all my other behringer mixers would have been helpful!  Thanks.
