From a quick google search it doesn't appear to have dedicated power amp inputs
That's correct. We used one of the regular inputs, turned the volume of the PM16 halfway open and ran Audyssey to bring the mains into balance with the other speakers. Seems to work fine for now. What grief are we risking here?
We could use one of the other outputs of the receiver, but I don't think that would allow us to use the mains as part of a 5.1 configuration. If using the pre outs of the SR6004 risks damaging the PM16 or the main speakers, we might be better off not using the PM16 at all.
