OK, so I've got my first live theatre sound gig coming up soon - the production starts Nov. 21st but we have setup and some tech rehearsal this coming Thursday. Anyone out there with some experience in this area that can lend me some advice or point me to a good resource? Here's the situation... they want a very natural sound so will be using as little amplification as possible. The only reason they're using any at all is because the acoustics of the room lend themselves to a lot of boomyness / echo / reverb and the voices don't project clearly enough in that environment to be heard in many parts of the room. The plan of the director is just to hang 3 choir mics over the stage... they expect this to solve the problem. My concern is that there will also be a 6 piece small orchestra on stage with them, and I'll have no control over the mix (no accent mics or body mics or anything are planned right now). So yah, any advice, or perhaps other forums on the 'net that this question would fit into nicely?
