Hi - I'm a brand new member based in Canada and a DJ working weddings and parties on weekends. I have just made the crossover into the wonderful world of digital and need some advice. I chose to work with MixMeister Fusion software, my old Numark DM1001X mixer (RCA inputs), a Peavey CS1000 (1000 watts) pre amp and a Behringer Xenyx 302 USB audio interface. I can't get the headphone preview when it's all wired up and configured. If I do get the preview, I lose the audio through the speakers. Can someone suggest what I need to purchase to run MixMeister Fusion? Thanks in advance for helping me make the leap! Drumbum.
