Based on our Prepare & Perform’ concept, rekordbox works (for both Mac and PC) like the leading music database management software, but is more creative and more DJ-friendly.rekordbox allows DJs to prepare more before their performance and opens a door to tools such as Quantize for perfectly synced loops every time.DJs can then export data to a USB device to access vast libraries of music files and perform live - without the need for extra equipment or any inconvenient rewiring in the club.Through the industry-first Pro DJ Link, music files and database data on one single USB device can be shared simultaneously by up to four players connected via LAN (local area network) cable, or with one LAN cable between two players. Plus, the data history of each DJ set is automatically saved and can be made into a playlist that can be loaded back into rekordbox.Another key facet of the CDJ-900 is its advanced HID (human interface device) and MIDI capabilities for native control of DVS (digital vinyl systems) via USB.There is also an improved audio output circuit, a new Wolfson DAC processor, and a built-in 24-bit/48 kHz sound card.Add to these features an overall enhanced design that includes a new display screen, rotary selector, carry handles and Kensington lock.Then check out the four-beat Emergency Loop and the three CDJ-900 exclusives: the Auto Beat Loop, Quick Return scratch feature and a Slip mode that enables DJs to perform tricks and return to their original flow in an uninterrupted fashion and you have the perfect tool for maximum performance.SPECIFICATIONS
