Hi, don't know much about live sound, but learning. My question is mainly in regard to mic'ing drums. If our drummer used 7 mics for his drumset, would it take up 7 xlr inputs on the mixer board? I'm reading this thinking it's a dumb question, lol...but we're thinking of micing the drums (7), lead vocals and backing vocals (say 4), and micing my cabs and two guitarists' cabs (3). If that's the case, it looks like I'm looking for at least a 14 channel mixer with 14 xlr inputs? I'd also need at least 5 monitor outs for each member. Am I thinking correct on this?
