cubase with alesis multimix 4 with fx

Hi, I’m a newbie with cubase. I bought an alesis multimix 4 with fx which comes with cubase LE AI 7. I connect it through my echo djx soundcard with my laptop. Try every configaration but still can’t record or hear any sound.
this is what i have- tosiba laptop, echo djx soundcard, alesis multimix 4 with fx and a condenser microphone.
please, can anyone enlighten me regarding the setup?
thank you
