Pioneer DDJ-T1 plugged to my Z-5500

Hello,

I am thinking about buying this Pioneer DDJ-T1 Controller put i am not use how i will connect it to my Logitech Z-5500 Computer speakers So have i understanded right that you had 1 USB cable from Controller to PC and a AC in the controller to wouldn't i need anything else and then i can have my Optical Cable from my computer to my speakers and then use the Pioneer DDJ ASIO Setting thing to make it work? or do i need to use thoes Master output or the balanced something on the controller it self.
