DJ Controller

DJ controllers are microprocessor-based devices used to help DJs (disk jockeys) mix music using knobs, jog wheels, encoders, faders, touch strips, backlit buttons, and other DJ software components. DJ controllers are designed to provide easier control of music software than computer or laptop components. Where DJ mixers mix audio signals, DJ controllers send signals to a computer and tell the DJ software within the computer how to mix the audio.

Most DJ controllers have built-in sound cards with two stereo pairs of two output channels that allows the DJ to listen to the audio through headphones before projecting the music. Many controllers use standard MIDI or HID and a USB port to communicate with the DJ’s computer. They generally only communicate with a few different DJ software programs that have been endorsed by the controller’s manufacturer. However, using the standard MIDI or HID protocols, other software can sometimes be made to work with the DJ controller.

DJ controllers are designed to mimic a DJ mixer and two turntables or CDJs. As professional media players and mixers take to using DJ controllers, manufacturers are including more effects, LCD screens, and touch-sensitive performance pads. Many also include drum pads, motorized platters, and fader tempo control.
