Reply to HELP! mapping/setting up audio-routing for xone 3D/traktor pro 2 (os x lion)!!!!

hey guys, please dont flame me for probably a noob question or a repeated thread.

i just 'upgraded' from m-audio torq xponent to xone 3d this week and im having a reeeeally bad time trying to figure out how to map it and setup the audio-routing.. no matter what i do, where i plug the rca cables, sound only come apparently from one channel (i want 2 deck only). i also downloaded a .tsi file but it doesnt not seem to work.

i know its not broken, i bought this used on ebay. and i really wanna keep it.

can anyone help me with a detailed step by step tutorial of how to setup the audio routing (mainly) and mapping?

thanks!
