Using McCormack DNA-0.5 Deluxe as Mono Amps

Would anyone be able to provide advice whether it is okay to use two DNA-0.5 Deluxe amps each as a mono amp on a system? I have a TLC-1 preamp.

If it is okay to do, how do you set each DNA-0.5 as right and left channels?

How much power would each DNA-0.5 put out?
