I'm in the process of designing and constructing a portable (transportable) sound reinforcement system for soloists' use during high school marching band half time shows and competitions. I expect to construct this in a short 19 inch rack on wheels plus 2 to 4 loudspeakers. This will be at least a 4-channel system. Ideally, I would like to power this from car batteries (and assume that I may have to use a DC to AC inverter). I was wondering if you have or could refer me to any design guidelines for such a system. I also need some suggestions on: a) wireless microphones that would be clipped to various band instruments, and b) use of your mixers for this application.
