DJM 2000 + CDJ 2000 and Traktor Pro 2

Hey guys,

I just bought Traktor Pro 2, Traktor Audio 2 interface and a Traktor X1 controller.

My question is, is it possilbe to setup my gear, so that I can use both CDJ 2000 as controllers in traktor,so that decks 1 and 2 (in traktor) are on channels 2 and 3 on my DJM 2000 mixer AND use decks 3 and 4 in traktor, on channel 1 and 4 on the mixer using the X1 as a controller? Do i need anything else than the gear ive mentionend? And how do i set up the audio for it?

THanks, appreciate it. :)
