I am kind of new to sound but I would really like to learn a few things. Unfortunately the man who was my mentor in everything tech, left because the school is cheap, and the new guy they hired admitted to not knowing anything about lights, and knows about the same as me on the subject of sound. Which is why I am very glad to have found this board. Now to the actual questions. 1. What does the low-cut button do? 2. At what point would I be using the preamp buttons on each channel? 3.Is there anyway to hook a computer to the board we have, to monitor frequency and such? (we have a 32 channel mackie analog board I will edit in exact kind later) I do have adobe audition 2.0 on my laptop. I guess that is it for now, any help would be appreciated. Oh and as a last note my teacher gave me permission to run the sound for our musical Grease this year, I ran the board last year and it was fun so I'm looking forward to doing it again.
