Greetings All: I have not seen a fit to the following situation so I am asking the Gurus on line. I am doing a community theatre production and have a powered mixer with enough inputs (6) but it really only has two outputs which I use for the main auditorium (Rt and left). I want to be able to power speakers on stage for different effects (door closing, breaking glass etc.) and it would be more effective for teh sound coming from the correct part of the stage. Any suggestions on equipment for how to get the correct sound to the correct speaker? I need 3 more outputs in addtion to the right and left for the auditorium. Thanks
