You need to download the software CDJ Aggregator. Then both CDJs will be merged into one Soundcard and you can assign Output 1/2 to one channel and Output 3/4 to another.
I cannot really believe that so many CDJ 2000 owners are out there. The price is ridiculously high ... who the heck can afford such players? Amazing guys! Not jealous, just stunning!
I cannot believe its not butter (sry could not help it lol)
i stream my mixes and Gameplay at http://www.hitbox.tv/MediaHeadzTv at Hitbox.tv you get no copy right strikes and im working on making a DJ community there
