A set of two MP3-compatible Pioneer CDJ-400 units with loop and tempo control functions. Accessories include only the power cords. *One of the platters is malfunctioning. It is stuck in the pushed-in position and does not return. We believe this will not affect CDJ use other than in VINYL mode (e.g., cueing and fine pitch adjustments). Both units read CDs and USBs without issue. If you would like to confirm any specific functions, please ask in the comments. - Model Name: CDJ-400 - Brand: Pioneer - Function: MP3 Player - Quantity: Set of 2 units - Features: Loop function, Tempo control - Terminals: USB terminal, Analog output - Operation Buttons: Play/Pause, Cue, Reverse, Eject Thank you for looking.
