Okay, having bought one of these beasts, upgraded significantly from SB Live 5.1, I find that everything I put in via my Behringer Mixer into the rca in, gets distorted. It seems hard to get a decent sound into the mixer...or is it out of the mixer because the sound levels go into the red on the Audiophile Monitor Mixer (on the pc). Do I need a preamp into the Behringer Mixer? Are my fx pedals supposed to be turned up all the way? The order of devices goes: Guitar-to- fxpedal- Behringer Mixer- Audiophile RCA in Any ideas??
