Reply to How to connect my Traktor Kontrol S4 to Pioneer DJM-900

I'm doing a new gig this weekend and wanted to know how to connect my Traktor Kontrol S4 to the Pioneer DJM 900 mixer (this is the mixer the club has). Can I plug into one of the Channels on the back of the mixer and if so, which one? If so, do I have to change any of my settings in my software, Traktor Pro 2? Or can I connect the S4 to my computer and then USB from my computer to the mixer?

Any help is much appreciated.
