Looking to run two power amps with this preamp- a bi amp congiguration- the manual says that you can run both XLR and RCA at the same time (there are three active outputs-2 rca 1 xlr) SO......i can hook up two amps to this output and run an xlr and rca or ,say,two rca's for a biamp situation.This may be an obvious question to some or,most for that matter,but i will ask questions first and shoot later,so to speak.So what is the best bi amp senario on this pre amp setup? Thanks!
