recording vinyl from XDJ RX2 to Rekordbox

Hi,

I have some problem with recording vinyl from XDJ RX2 to recordbox.

If I start the vinyl there is no sound input in recordbox. recordbox told me, the Master Level is deactivated. please change master level on your XDJ.

The sound works from the normal speaker. There is no signal in the REC view.

Second --> The preview doesn´t work.

Thanks for your help
