How should I set the DJ application's audio settings when the mixer mode is set to the "XDJ-RX"?

When the mixer mode is set to the "XDJ-RX", two channels worth of the DJ application's sound can be input to the XDJ-RX. Set this as shown below.

Windows

-L: PIONEER XDJ-RX OUT 1
-R: PIONEER XDJ-RX OUT 2
To input to channel 2 on the XDJ-RX:
-L: PIONEER XDJ-RX OUT 3
-R: PIONEER XDJ-RX OUT 4
