Reply to xone:dx and cdj's?

does anyone know if you can hook up cdj's to the new xone:dx ?

like if you look at this video, the there is a denon next to the xone:dx and the wires hooked up into the xone:dx looks like its coming from the cdj. if you look at this video http://www.youtube.com/watch?v=yXGX7zcpIu8 it shows the behind of the xone at 5:35 min/sec

im believeing i will get the xone:dx and also use it as a mixer and also buy some cdj's one at a time like the cdj400,1000,900,2000 and play around with them since clubs will carry those so it'll be good to be familiar with them

and its funny how he doesnt say how you can hook up cdj's cause those 2 cables red/white are hooked up to that cdj. but i just want to confirm.
