Hi all.

Sorry if this is a dumb question.  but I've just started.

I've recently come across a pair of cdjs 350 and a djm 600 mixer. I am also very interested in using my usbs to play shows whilst preparing my sets on rekordbox.

A quick question though. How do I plug my laptop running rekordbox dj plus pack into the cdjs and play using my laptop. This is without using the usbs too, I'd like to completely play using a laptop cdjs, and a mixer. I know the new pioneer rekordbox has been developed to compete with traktor and the like so I would like to give it a shot.

Do I need any other hardware, such as a rane sl4 audio interface or something like that, typically for use with serato or would I just need a USB to controller cable (laptop to plug into cdjs cable, not sure what this is called).

Any advice will be appreciated.

Regards.
