Question on routing

[mcrackins]

DISREGARD: Figured out. The stereo channels on my board were channel strips 3 & 4. I did a novel thing and read the manual    Channels 1 & 2 were mono

I haven't picked up my new audio interface yet, so I have a question on my current setup
I presently have an old Behringer Eurorack MX 602a mixer that I'm using to go into an ancient M-Audio 2496 card.

I have the  two line outs from the Drumit module going into track one and two on the Behringer.
On the Drumit module I have:

I have the headphone out on the Behringer going into the Line-In on the Drumit module to hear the Studio One DAW playback

Line/Stereo/Sub
Out 1-2/Sub

I'm not sure if I have it set correctly as the the DAW drum recordings don't sound stereo??

Any pointers or there a setting I may be missing?

Do I need to have both 2box outs plugged in or can either achieve stereo with present setup using one cable and one track.
