Need help with connecting a turntable to the mbox 2!!! Help!

[dmt2828]

Ok so i just got an old technics turntable which works in perfect condition. Now i have the turntable connected to my mbox 2 through the two s/pdif inputs (the red and white inputs). Im trying to sample the music from vinyl and record it into pro tools le 7. Maybe im missing something to do this, so let me know. I currently don have a mixer for the turntable and im only using one turntable. My problem is i cant hear any audio from the turntable when its playing. I already tryed going to the setup/hardware and selecting the s/pdif for sound source and still no sound. So any help would be appreciated..I dont know if later i need an audio editing program to select a portion of a song to edit. Later though i am getting recycle 2.1 for reason 3.0 to start sampling with. so any advice would be appreciated... I just wanna hear sound from my monitors from pro tools le 7, to hear the turntable...
