Hey guys, just snagged a svt2p preamp and planning on pairing it up with a QSC-RMX 850. Just have a few quick questions: -Is the power amp ok to run through my current cabs, which are ampeg classics 115 and 410HE. (im pretty sure there rated at 250-500 and 500-1000) -Im not quite sure what the difference is between running the cabs stereo and mono, is it simply that the sterro is running both cabs to seperate connections at the amp, and mono running one to the amp and the other to that cabinet? Which is better/more effiecent? -When connecting a pre to the power amp, is standard speaker cable ok? Thanks alot guys.
