Question

I have a Studiolive 32R and plan to purchase a 32SC to operate the board.

Can I run speak outputs from both units at the same time?

The 32R is closer to our main speakers, and the 32SC is closer to our recording and monitor outputs, so it makes sense to run separate outputs.

Answer 1

In a basic setup (non digital-snake), yes you can.  Though, the question you presented did not include a lot of other information to determine how you would plan to run the consoles (analog/digital), FOH/Mon, and what are the purposes of the speakers would be.
