Audio interference Problem

Hi all,

i have a problem with my VL12 when i use a timecodevinyl. There is a disturbing noise near the base. And no, it´s not the timecode signal. I never heard this noise on my technics 1210. Only one of the VL12 have this problem. Denon said, that everything is okay. I crosschanged the systems, the vinyl and tried the digitrac and qbert system. I uploaded a video to show the problem.

Thank you in advance
