I know my inexpertise is probably annoying, but I'm doing an independent study at my highschool, and I'm trying to put together a quick reference guide for the theatre equipment we have. We don't have manuals or anything, and though I've used the equipment for several shows in the past, I've never received any formal instruction in it's use. The problem with our equipment is that the man who set it up did it alone, and never trained anyone to replace him. Unfortunately, he was banned from the school campus because he was buying alcohol for the students, and now we have a complicated setup that no one knows how to use beyond the basics. So, here is a simple question that I'm sure qualifies me as a complete newbie: Are channels generally used for single lights or groups of lights? With the setup that we have, it seems like the channels being used are set up with groups of similar lights of at least three. The submasters are then groups of the channels, but there is no way to control individual lights. So, is that normal? Thanks for your help.
