Problem between traktor pro 3 and kontrol z2

Mattt

Hi y'all, i need your help before getting mad.

I got a S4 that is working very well with traktor pro3, and a z2 within i can't change the tempo and also calibrating is ******.

Any idea ?

I think i finally found the problem:

My turntables (stanton st150m2) have no ground cable, but could be plugged phono or Line. If i use the z2 with Real records thé music sounds better in Line mode but Traktor prefer thèm in phono mode.
