I'm selling this because I switched to Serato and haven't used it in a long time. It's ready to use with just one USB cable. A type-B cable is also included, so you can use it with Rekordbox via USB or connect it to a PC. It works perfectly fine! The XDJ-RR is the perfect 2-channel all-in-one DJ system for learning how to use the CDJ-2000NXS2 and DJM-900NXS2, which are supported by many top DJs. It has the basic functions of the CDJ-2000NXS2 and DJM-900NXS2, and with this one unit, you can select and mix music with the same operational feel as the equipment found in clubs around the world.
