Connecting MPC to MOnitor Speakers through DJ mixer

I have my turntables running through an mbox which powers my monitor speakers. how can i connect my mpc so i i get output from my MPC through the speakers?

I got sound using 1/4 & rca cables but the sound is super distorted.

any help would be appreciated

get at mixer

how about you run your mpc through your mbox, then run your turntables through the inputs of your mpc.... that would work!!

x2 get a console or dj mixer with proper inputs/outputs
