noise when playing vinyl

Hi there, i've got some problems connected with umixcontrol pro2. I think i can't even explain it right. It appears to be not possible for me to connect it properly with turntables. It recognizes the records, u can hear them play but with noise , noise all over the music; when i`m trying asio4all v2 its less noisy, but still not playable. I'm using a soundcraft efx8 mixer connected to some active speakers.
I connect the turntables (Numark ttxII in line mode) to the inputs of the ucontrol (line). But when i want to play vinyl or timecode nothing is to be heard except the noise at high volumes. (i followed all the instructions in the manual for the audio setup inthe prefrences; external mixer mode, dual stereo, but nothing works) Whats the problem? I had the u46mkII before and it worked. Please help, I#m getting desperate. thanks in advance..
