Djm 900NXS2 does have dual audio output for live streaming?

Hi, unfortunetly i'm dont have any experience with dj desks, but we want to make a live stream for our next party with direct audio.. 

Master 1 connected to the speakers,

And if i connect a rca to jack cable to my pc with master2, it will have audio on both?

We want to connect it without usb. 

I was looking for answer on internet, but i didnt found any definite answer.

Thanks for your help :)
