How do I route out of StudioLive 24.4.2 to ADL 600 for analog summing

FYI...It says in the manual that the Monitor bus is a summing amp in Latch mode. Currently I'm ruing out the CR outputs to a monitor station.

My goal is to run a song mix in Studio One 3 Pro through the ADL 600's and bounce the mix down to a left and right chael. The mastering diagram in the ADL 600 manual shows lines coming out of outputs 1,2 on the Audiobox 1818VSL.

I'm unclear on what outputs I need to use on the StudioLive 24.4.2 and how I need to set it up in Studio One. I've seen videos of guys ruing the mix out of Mix Busses but still need help with wiring correctly.

My main confusion is the Monitor Bus as a summing amp. I'm assuming that I must use the summing amp to accomplish my goal.
