Hello everyone, I will be running a talent show with four wireless mics for the first time (I've mixed 4 shows with all wired mics before that). I've got the basics of mixing and using a sound board, and I know how to patch my high school auditorium's system, but that's about it. Any tips on working with wireless microphones? I know the obvious one of making sure their faders are off when not in use so as to avoid unprofessional backstage noise. What exactly is the role of the person backstage managing the microphones? What situations do they need to react to, and how? We're going to borrow four from our choir director's band, and he will be able to help us if we're stuck, but he's also directing the show, so I'd like to make sure I and whoever is in charge of them know as much as possible. Any suggestions?
