So You Wanna Be A Sound Guy
by Mike Lockrem
This is a quick start, nuts and bolts, real world guide to being a sound guy/girl. This does not go deep into the science of sound or electronics. This book shows you how to set up and test the parts of a PA, mic a band, sound check them, and how to use the mixing board and other devices in the booth. It also contains a lot of advice on how to work with bands and how to run a show.
