Reply to Xone k2 setup with a club mixer...some help

hi guys,

my setup is a macbook running traktor pro 2 with a k2 controller.

can someone tell me if this setup is correct?

output routing:

internal mixing: (as i plan to use the 4 channels on the k2 for volume etc)
output monitor: front left/front right (as im using the k2 for monitor cueing)
output master: this is where im unsure. do i leave this as not connected?

what i want is my rca jacks to go into 1 channel in the club mixer, put the volume up, then i control each deck & volume from my k2.

thanks
