I just got a QSC PLX1202, but I dont have a cab yet, but wanted to set the switches so when I do get my cab, I'll be ready to rock. I'm gonna be running in bridged mono at 4 or 8 ohms, and have all the switches set to the right. Is that the right set-up? What should I have the Low Frequency Filter set at? Thanks for your help. Oh, and also, I'm running into an old Sunn 16 ohm PA cab, a 1275, which has a 15" speaker. Is this ok? It has parallel inputs, can I plug into either one of those?
