Almost looks like some noise or bad wiring / grounding...

isn't there any other audio signal going to the phono in on the mixer?

no other signals ! only this one . Just for indication, i installed Virtual DJ , and all was ok with this setup !

this sound i hear when i'm on DVS , scratching slowly : https://www.dropbox.com/s/s2tjoaswh0bxbq6/01%20No%20Title.wav?dl=0 

when i'm without any timecode, and hit on the ToneArm , this cracking sound with "power noise" i hear too !

Rekordbox team, please help !

If the player goes backwards, you may have the L/R audio outputs reversed.

As for the crackling, you removed the files so I can't see / hear what's going on. Have you calibrated the signal within the rekordbox preferences? Is the turntable properly grounded?

Just installed this version and nothing changes . 
here is the parallel sound i hear only when i'm scratch (when the music is playing, and i'm not touch the vinyl - everything was ok)

here is the video :https://www.dropbox.com/s/o7c4gu66omuwxzw/IMG_8385.MOV?dl=0

with this setup , i run Virtual Dj, and all was fine ! without any interference !

Have you manually calibrated the signal input? You need to let it play, then click the START button for it to calibrate properly.

That simply sounds like it's not receiving proper signal.

yes! the calibration its help, but still i hear the electro parallel sound !

I just watched the video again ... which deck is running the DVS? You seem to be scratching and the calibration signal is on deck 1, but then there's also signal on deck 3... can you provide some detail about your setup and configuration?
