Reply to DJM 700 with Traktor 2.6 pro

Hi there, I want to ask, do I have to use atleast Traktor Audio 2 to connect DJM 700 to work with traktor? I bought Numark DJ Io which is 2 channel output, its ok 2 channels is all I need, but it seems doesn't work at all with DJm 700 o.O So any suggestions how do i connect DJm 700 to traktor? I believe traktor audio 2 supports midi, and numark dj io doesnt.
