The VCI-400DJ, a professional 4-channel DJ MIDI controller dedicated to Serato DJ, and based on the acclaimed VCI-400 hardware. The VCI-400DJ is available as a limited edition, shipped with a free upgrade licence to Serato's flagship pro DJ software, Serato DJ. The VCI-400DJ is the perfect solution for DJs who have been seeking for a premium controller in a robust and compact body. The association with Serato DJ has made the VCI-400DJ the most reliable and intuitive portable DJ controller in it's league.

The VCI-400DJ was designed to give long-term durability. The thick aluminium facepanel and die-cast corners provide rigidity to the whole hardware. The large aluminum Filter knobs are also a distinctive Vestax design that has been inherited from previous Vestax quality hardware.

The integrated audio interface uses a studio-grade asynchronous USB streaming system, to provide low-latency, bit-perfect audio at 24-bit / 48 kHz resolution. This audio system combines a XMOS dual-core digital processor with carefully selected analogue components, to deliver clear and powerful sound. In addition, the EQ response of the integrated Stand-alone mixer was shaped from the legendary PMC-55 club mixer.
