DJ equipment typically consists of a mixer, turntables, and speakers. A mixer is a device that allows a DJ to adjust the volume, EQ, and other settings of the music being played. Turntables, also known as record players or decks, are used to play vinyl records. Most modern DJ equipment also includes a digital audio interface that allows a DJ to play music from a computer or other digital device. Speakers are used to amplify the sound of the music being played. Some DJs may also use headphones to preview and mix music, and may use effects pedals or other specialized equipment to enhance their performances.
