Pioneer CDJ-400. Only two CDJs. No mixer included. As a bonus, I'll include DENON headphones. The headphones are quite deteriorated, but the sound is still clear. Reference: High-performance 2-channel full digital DJ mixer equipped with an in-loop sampler. While inheriting the basic functions and operability of the DJM series, which is popular in discos/clubs around the world, it achieves even higher sound quality by going full digital at 96kHz/24bit. Mixing is performed by a 32bit DSP without degrading the sound quality, and at the same time, an ideal filter generates sound optimal for DJ play. It automatically detects the tempo (BPM) of the song being played and applies effects accordingly, enabling various sound productions. In-loop sampler for real-time remixing 3-band isolator equipped for each channel Other features By connecting with a control cable, fader start play is possible, where the Pioneer DJ CD player starts in conjunction with the fader operation.
