Im getting probably a QSC PLX 1602 soon and came up with some questions while looking at the back panel. 1. How do you connect two cabs to one channel? I only see one banana plug out, and 1 speakon out (for each channel). Would you have to use each of those? 2. Can you only use 1 cab when bridging at 4 ohms? What types of cable do you have to use when bridging? I have more questions, but just can't think of them right now. I'll post them when I can think of them. Thanks for any replies!
