Your mixer has to have RIAA phono corrector, which needed for vinyl record (f.e. Soundcraft Compact).
I assume your mixer A&H ZED 10fx doesnt have it.
So, you will have 2 ways to sampling with AT-120LP:

  1. AT-LP Via USB to PC/Mac, then to OT (CF/USB)
  2. You should buy additional RIAA phono corrector (or interface/DJ-mixer etc) for your mixer for Direct sampling via OT inputs

UPD: Sorry, I was wrong. AT-120LP has built-in phono corrector
