sound setting in virtual dj pro

 how can i set rca outputs 1,2,3, and 4 as speaker outputs?  it is currently set up as outputs 1 & 2 as master and outputs 3 & 4 as headphones.  i want to be able to connect speakers to all four outputs.

Such as to sent each deck to one stereo pair (Deck A on Output 1-2 and Deck B on Output 3-4 ?

You will need to apply the following configuration:

- Input : None

- Output(s): External mixer > Deck A: Output 1-2 / Deck B: Output 3-4

- Soundcard: DJ Console XXX
