Ableton, Audio 2 + KRK's, please tell me im being stupid.

Right so my KRK's eventually came, happy as larry, plugged straight into the s4 and boomed for a few days.

This morning i thought of doing a bit of producing so looked out my audio 2 soundcard (only card i own with 1/4 outs) hooked it up and the sound is only coming out of one speaker,

Ive hooked the left KRK upto A and the right to B

Seemingly A is channel one and B is channel 3.
So i can only get one working at a time.

Help?!

The Audio 2 has two unbalanced 1/4" stereo outs and the s4 has 2 balanced 1/4" mono outs.

You want to come out of one 1/4" stereo jack on the audio 2 and split it to the left and right channels. The 1/4" to RCA adapter it comes with would work and then hook each monitor up with one end of the RCA. The Audio 2 is unbalanced only so the 1/4" outs really don't matter.
