Turntable: An electronic device that plays records and consists of a spinning platter and a tonearm with a cartridge. Disco DJs used two turntables and sometimes three in a discotheque setting to create a non-stop music experience. While the early Technics SL-1100 was the first real Disco DJ turntable it is the ubiquitous Technics SL-1200 mk2 turntables that were, and decades later still, the professional DJs choice when it comes to turntables. . http://en.wikipedia.org/wiki/Turntablism
