[PROBLEM CLIP] USB REC. PIONEER XDJ-RX

Hi! I have a XDJ-RX (ve 2.10) and this is my problem:

When I listen the mix, that I had recorded with the function "usb 2 master rec", the mix every 2 or 5 minutes have a clip or distortion, the sound is like "tak"... I dont understand why. I tried to recording with the master and gain volume at 0 db and later adjust the volume with audicity, but the problem is the same...
Solution?? Thank's!!

When I am recording, using a Samsung Hi-Fi connected to master with RCA.
