I have 2 soundtracks that I want to play through out my haunt. A thunder sound track and my graveyard sound track. I need to know the best way to send these tracks through some sort of mixer I guess and then through a PA system or powered amp. Not sure exactly how to go about doing this. I want to have control over the Volume or "level" of each track and then the master volume that is coming through the speakers. Hopefully this makes sense. I do have a small portable 4 channel recording studio that hopefully maybe I can use to send the tracks through as the mixer, but then I guess I still need a powered amp or PA system to send the mix through, in to either a powered amp or PA system. I was using two stereos last year with the speakers from each stereo sitting next to each other. One stereo and set of speakers for each soundtrack, but the sound quality wasnt that great and I would rather just have 1 centralized sound control. Any help would be greatly appreciated!
