So I am a newbie with consoles. Messed with it a bit last night for the first time. I ran one out ( L main) since I wasn't sure how to hook it up stereo or if I even should ( there is no dedicated mono out on this one. It is an older one). Can someone tell me the best way to hook it up, mono or stereo and how to do it? I have a crossover and 3 power amps, subs, mains and monitors. How do I hook up a Microverb 4 as an insert to the lead vocal channel. Thanks.
