DDJ SX- Roland GO: Mixer Pro

HI, 

I am finally about to get my hands on a Roland GO: Pro to stream some sets. I am wondering if anyone has had experience with this and the DDJ SX. I am wondering if I should run the line in to the Roland GO: Pro from the booth output or the DDJ SX's second audio out (RCA). I have a ton of cables but want to confirm I have whats needed before it arrives. 

Thanks,
