I use the 7.0 Virtual DJ and what I do cause Im lazy is I use the right hand deck only. I will stack my playlist start automix and then just drag and drop as needed throughout the night. Problem is I had no way to Que with headphones. SO I bought the Numark Mixpro board But still cant figure how to use the left hand deck to que w/ headphones w/o it going out in the main mix. My tech guy try different configures but as of yet didnt work. So as of now I hooked up a set of phones to the left deck rca jacks and w/o a preamp well it sounds like shit...and Im sure it can be done ...HELP.
