Building upon the success of the original CDJ-900, the Pioneer CDJ-900 Nexus – Professional Multi Player is a CD, USB, and Wi-Fi enabled audio deck capable of playing WAV, AIFF, MP3, and AAC files. The unit features a 24-bit / 96 kHz professional-quality DAC processor, the Pro DJ Link system, wireless functionality, and a full color LCD display.

The media player has a front-loading CD drive, which can read manufactured audio CDs as well as CD-R/RWs. External storage devices, such as flash drives, connect to the USB type-A port on the top panel. The CDJ can utilize these sources without any assistance from a computer.

The Pro DJ Link system allows up to four decks to be linked together over LAN cables to share audio sources. Music from a hard drive or USB flash device can be cued up and remotely played from any deck in the array.

One touch tempo-sensing looping functions enable quick beat-matching during live DJ sets. The CDJ can also transmit MIDI signal from its back panel USB type-B connection, which allows control of third party DJ software from a laptop. The built-in HID technology often eliminates the need for a control disc.
