We currently have our mains coming in as 1 XLR and our subs coming in as 1 1/4″. We have a crossover point and all that set up correctly. However, on the board I am trying to figure out how to best route it. On our old board we had it coming in as an AUX. Currently, I have it patched to “MAIN L/R”. However, I would like to pass it through a matrix to get more control. I was reading the reference guide and it says this is a possibility. How would I do that on the I/O or routing screens?
