PIONEER DJM750K DJ Mixer Hit Boost FX to engage and control Sound Colour FX and Beat FX simultaneously, and manipulate the parameters of both FX depending on how fast you twist the large chrome knob. A built-in USB sound card allows simultaneous input/output of stereo signals from 4 ins and 4 outs, while 96 kHz/24-bit high-sampling processing ensures the audio quality. Connect the unit to your laptop or computer via USB and the settings utility tool will automatically open, allowing you to configure the mixer, sound card and audio routing to suit your preferences. This mixer is equipped with a 32-bit A/D converter to digitise and enhance sound quality for all outputs, while the 32-bit digital signal processor suppresses digital noise. Even analogue noise is reduced through balanced hybrid operation amps and output circuits.
