Can´t monitor traktor from ssl2

Thecostag

My soudcard SSL 2 has 4 audio out channels
2 main outs: outputL - outputR
2 monitor outs: phonesR phonesL

I select the SSL2 from traktor audio setup/audio device
Then on output routing i want to route
Output monitors to phonesR and phonesL, for monitoring
Output Master to outputL - outputR

BUT

Traktor doe´t have that option for the SSL2 it only lists the main outputss of the SSL

Is this souncard unsupported?
What am i doing wrong?

The Solid State Logic SSL 2 has two input and two output channels - not four. As it is a recording interface this means mono channels! You can switch two mono and select one output as main output and the other for monitoring. For Traktor you usually need at least four output channels on your interface if you want to use stereo. A deck in Traktor is two output channels.

The headphone outputs only mirror signals and are no outputs of their own.
