The CDJ-2000 fizzes with fresh DNA and can play music from multiple sources, including CD, DVD, USB storage devices and SD memory cards. Through the industry-first Pro DJ Link, music files and database data on one single USB or SD device can be shared simultaneously by up to four players connected via LAN (local area network) cable. Another key facet of the CDJ-2000 is its advanced HID (human interface device) and MIDI capabilities for native control of DVS (digital vinyl systems) via USB, making each deck full Serato, Traktor, Virtual DJ, and Rekord Box compatible.
