I am interested in learning how to run my school's soundboard. We have a Yamaha M7CL. If there's a difference in the 3 versions I saw... I think it's the 48V... otherwise, I believe that it is the standard one...

anyways, I don't know anyone here, but if you could help me along with my self-studies, that would be great!

so first off, I would like to know if anyone knows where there is a manual that isn't confusing... Also, i'm trying to learn certain terms about the soundboard (i.e. phantom, trim, PFL, AFL, etc...)
