Well then you have a basic idea. The signal on this mixer can be routed in a variety of ways, and to numerous channels. Effects, dry, eq'ed etc. One of the best ways to get started is to use the EZ Routing button and to see what it does.
The documentation basicly blows so there is a lot of playing you'll need to do, but all in all it's pretty easy to get the hang of. Once you do, you'll love the value of this piece.
I will be replacing it soon with the 2480, but will bekeeping this as a midi mixer.
