I am kinda new to live sound and have a outdoor concert this weekend. I am wanting to use my sl2442fx pro and I have 3 amps and 6 speakers. I have a small crown that I would like to feed monitors on stage and have 2 other high watage amps in which I would like to feed 2 speakers to crowd all frequencies and 2 more I would like to us as subs. I have many cables and adapters just not sure how I can separate the stage feed volume and still control crowd volume. Thanks for any help.
