I'm looking for a small (cd, 4 mic) rack-mountable sound board that is easy to use, reliable and can be used by someone that has never seen a sound board before. This is going to be used for a backstage control system for small assemblies and rentals so that no one has to be there to run sound. Any ideas? Also, I have to figure out a switch for the speakers so that we can switch between the small and the main board. I would like it to be switchable in the booth and in the back. Any thoughts on this? Thanks.
