As I get closer to to gigging with my new band, I have some hookup questions.
I'm running bfd on my macbook out to a motu ultralite. If I take the main outs of the ultralite directly into the board or my amp, I'm getting a hum sound. Now granted the wiring in my house is yucky, so it could be a ground loop. Do I need a di box? What exactly does a di box do? If I do need one, should I get passive or active?
Also when we do play out, as i see it, there could be a few scenarios. One is that I can run directly into the board, and have stereo, with the club supplying monitors. The other is that I have to run into my small roland keyboard amp (for a monitor), and then out of that to a main board.
I just want to be prepared to cover my butt in any situation. All info deeply appreciated.
