I'm going to be djaying (I'm using the term very, very loosely ) some events for my church and want to use my Powerbook to play the music through a sound system. I'll be running it to a mixer first and then to 2 monitors. Has anyone ever do this? If so, what will I need to configure on my Powerbook to do this? Or will I be able to just hook up the cables and play music from iTunes? I will be looking at the actual mixer this coming Sunday to see what type of cables I'll need. Hopefully I can find the right kind. Thanks for any help you can give.
