What is a cdj?

CDJ stands for compact disc jockey and it is a type of digital turntable used by DJs to play and mix audio tracks. A CDJ typically consists of a CD player, jog wheel or jog dial for precise track manipulation, pitch control, a display screen for track selection and information, and various buttons and knobs for controlling different aspects of the audio playback. CDJs are commonly used in clubs and at music festivals worldwide, and are often preferred by DJs who prefer the tactile feel and experience of vinyl but want the convenience and flexibility of digital audio files. They can also be connected to other DJ equipment, such as a mixer or DJ controller, to create a complete DJ setup. Some popular brands of CDJs include Pioneer, Denon, and Numark.
