Audio problems w/ rekordbox dj and my aero controller

Here is my problem....

I switch to performance mode at home on my Aero controller and load up both decks with tracks. As I go to dj, music is only directed threw channel one but full controll with the controller on the separate decks. I can't find anything to help me out, can some one please email me with some help. 

Thank You.
