What else do I need for DJing, as well as the DDJ-XP2?

The DDJ-XP2 is an add-on controller for Serato DJ Pro and rekordbox dj.

You'll need the following setup to use either of these DJ applications.

・ A PC/Mac running the DJ application
・ A DJ mixer or DJ controller that supports the DJ application
・ Powered speakers, headphones, etc.
