So, Like a complete dufus I was trying to carry on two conversations at once while hooking my rig up and I wired it up like this: Power amp Bridge / mono out to speaker cabinet in #1 AND power amp input into the cabinets parrallel input #2, AND TURNED THE BASTARD ON!!!! Basically I looped 1200 watts thru my amp. Speakers flapped, sparks flew, the room was filled with stench. Thank God the Speaker Cabinet is fine, probably cuz the amp's peak power is well below the rating for the cab. Now, only side A of the Power amp ( Crest LT1000 ) works, and I'm afraid to use even that. Side B reads Clipped when you turn it on and is totally non-functional...... BEST PART YET: I have Three shows in the next five days, only one of which I can run a DI. Advice......?
