Reply to Problem with Studio Monitors and Kontrol S4. NEED HELP PLEASE !!!

So I have the kontrol S4 and I recently just bought a pair of Fostex PM.4n professional Studio Monitors. I want to connect my monitors to the back of the S4 directly using XLR cables and 1/4" adapters. So meaning the cables are plugged into the "1" and "2" 1/4" inputs. ( not the RCA's)

I just wanted to know what my settings should be under "Output Routing" in the Preferences setup so that I get the best sound and it works perfectly. Meaning, what should be my Output Master and Ouput Monitor and all those other settings tabs.

All drivers and updates for the software are up to date as well.

I also have headphones plugged into the mixer for pre-listening and monitoring (cue-ing).

So if anyone can help me with this problem then that would be greatly appreciated. I need a solution to this as I have a gig coming up in 3 days and I can't afford to mess up my setup. Thanks once again everyone for your help !
