Hi, my name is Robin and I am the auditorium director at a high school, I have held this part time position for 3 years now and I was the back up director for 4 years before that. I am having problems now because, due to budget constraints my duties have now been cut back so that now I only operate the lighting and sound for outside rental groups. The student operate the systems for school functions. So far they have melted a hole in the monitor to the light board, spilled pop in the sound system, and lost the operation manual for my state of the art (1986 or so) minstrel plus sound board, they then reprogramed it and they do not even know what they did. I need a manual. Help!
