There are USB and SD card slots for adapting removable media devices and accessing AIFF, WAV, MP3, AAC and DVD-ROM files. Up to 4 CDJ-2000 or CDJ-900 players may be linked to share a single music source with Pioneer's Pro DJ Link, and organizing music files is made easy with the included Rekordbox Music Management software. The coveted DSP features of the CDJ-1000 are all present, and its 6.1" full color LCD panel and Graphic User Interface make title searching and operation in dimly lit clubs very easy.
