Gary –

To perform a foh-monitor split, (let’s assume 24 channel of each):
-assume input ch. 1-24 are assigned to mixrack inputs 1-24 (A1-C8).
-go to and “select” ip channel strip 25, go to the preamp screen and select “A1” (ch 1) as its input, from the drop down menu. Ch 1 & ch 25 now share the same preamp section.
-use the same procedure for any other channels you wish “split” into mains & monitor functions. ie. 2-26, 3-27, 4-28, etc.

Essentially, you go to any channel strip and assign its input port, one port can be assigned to a number of channel strips.
