After recently getting back from MHC in Columbus I thought I would join on here and try to get some ideas. I run audio for a very low budget haunt and we run CD's. It would be nice to have some room back in our control center. Last year I ran 12 sets. This year I want to get away from the receiver and CD player per room and go to MP3 and amps or server, just unsure how. Does anyone have any ideas how to shrink this? Thanks!
