We have a gymnatorium and have to setup and strike twice a day and sometimes 3 times a day. our last Mixing board (24 channel Yamaha) was destroyed because we were moving it so much and plugging things and unplugging them. We just built a booth up in the wall that makes this process so much better, but the problem is that the sound is horrible in the hole in the wall. The hole is 4'W x 2.5'T and is 110' from the stage. We put moniters up that feed directly out of the board, but it is not dilayed for the distance. My plan is to hang two mics in the house that capture the sound, and have that be the only sound that goes to the monitors. What have you done or what can I do to get a better sound?
