DriveRack PA+ with QSC KW Series

Poppafry

I am running the DriveRack PA+ with 2 - QSC KW153 3-Way loudspeaker system and 1 - QSC KW 181 Subwoofer.
I am having trouble getting the sub to work.
Could someone help me with the proper connectivity and set up in DriveRack?

Assuming that the QSC's are not in the wizard, select Passive -Custom tops and Mono subs - Custom.

Connect the tops to the high outs, and the sub to left (mono) low out.
