The PMX-20 is a 4 channel mixer designed to meet the needs of the most demanding scratch addict, with a highly adjustable Innofader-ready crossfader, 8 RGB performance pads per side, and professional inputs and outputs (including booth output). The rugged all-metal chassis means the PMX-20 is a professional DJ mixer which can take a beating for years to come. The real secret sauce in the PMX-20 is the MIDI and audio interface functionality. Every control on this digital DJ mixer sends MIDI – not just the dedicated MIDI functions. This combined with the built-in 4 channel audio interface allows the PMX-20 to also work as a fully stand-alone MIDI controller. With the PMX-20 you’ll get a lot for not a lot.
