Sampling and playing from dj mixer to 1000

Hey, i've recently bought a 1000 and i plan on sampling from my dj mixer (vestax pmc-06) which is hooked up to my turntables (tech 1200s). I've learned that i can play the mpc through my mixer by hooking it up to the second channel (replacing one of my turntables), but there is still alot of distortion when i play the mpc through the mixer, i think i need a hum eliminator or something like that but is there anything i can do in the mean time before i get that? Also, my main problem is i can't figure out how to sample from the one turntable i have hooked up to the mixer to my MPC.
i have two 1/4 inch to RCA cables and two 1/4 inch on both sides. I was thinking I may need to hook up the MPC to the mixer with the 1/4 to RCA cables to the Line Out on the mixer, but im already using those wires to connect the MPC to the second channel on the mixer. Do i need to buy another set of those cables if i want to play the MPC through the mixer while sampling from the mixer at the same time?

I know i may have made it sound complicated but please let me know if you can help me with this problem. thanks alot

plug it into line and not phono. that might be the problem right there
