XDJ RX2 Line out

 I want to stream a DJ set from the RX2 via OBS studio to FB Live.

I don't see a Line Out in the back that can go directly into my computer.  

There is only one master output that goes to my studio speakers.  I am using HP

laptop.  

I am trying to wrap my head around how to get the audio from my RX2  into the

computer.  

Please help!
