I just got my PLX 2402!!!!!! There seem to be a lot of dip switches in the back. I want to run the QSC bridged into an 8ohm Avatar 212. I know the dip switches that have to be turned on to bridge the power amp, but what about all of the filter dip switches? Should I leave them off? Maybe Bob from QSC can give me some tips. Also, I'm still undecided on a preamp. I'm going to be trying several, Fender TBP-1, Demeter VTB, BBE BMAX, Tech 21, etc... By the way, I'm selling an Eden WT-800, it's in the for sale forum.
