I'm looking for the input of some professionals here. The tech head at my college is looking to purchase a new sound system for the auditorium. Currently, we have a "house" system that looks to be from the eighties, except the amp is only two years old. I don't know the model, but I can find out. We hired a sound/light firm to come in to look at designing a new system, but here's the catch - it would basically be a portable system designed for our auditorium. Basically, we already use a system like this. For everyday speakers, we use the 5-channel mixer (volume control only because there is no eq or gain adjustments) and then output to two speakers mounted above the stage behind a wire mesh and also to a DVD recorder. For large productions (talent shows, band nights, theatre productions) we set up two or four speakers just in front of the stage and run the sound through them from a board and amp that we set up from various locations. For less crowded events, we set up in the middle of the auditorium and run a 50 foot snake down to the stage or for really crowded events we set up the sound board in the back corner and run the mics and speakers through the boxes on the stage to the booth into a 15 foot snake to the board. If it is a small operation we use a 12 year old Yamaha amped output 12 channel, and if we need a lot of mics (usually for musicals and concerts - also usually wireless mics) we use a Mackie 36 channel into an amp in the booth to the speakers just in front of the stage. I and the other members on the tech crew want to put in a new house system using the Mackie, but our tech head insists on using the portable system. So the sound engineers are putting together a $15000 proposal for a system that won't be built in. What's your opinion? Note: One possible reason for this is that we cannot get a lift on stage or in front of the stage without taking out ten rows of (very heavy) seats by unbolting four bolts per chair. The closest we can get is about 30 feet back from the proscenium. Also, we have a large pipe organ (60 ranks) that goes over the wing on stage left and goes over about fifty seats (eight rows.) *edit* - it usually requires a crew of 3-4 people to set up for a talent show/ band night that takes 45-60 min set up and 30-45 set down. for musicals it's 2-3 people that take about 30 min a day for about two days - one for basic set up and one for fine tuning.
