Technics SL-1210 Mk2 mode quartz synthesizer direct-drive turntable: one of two, by Matsushita Electric Industrial Co., Ltd., Osaka, Japan, 1999. The Technics SL-1210 Mk2 mode quartz synthesizer direct-drive turntable would normally operate as a pair: both connected to the amplifier and speakers through a cross-fader. This is to mix the outputs of two separate soundtracks, a procedure which is the foundation of 'mixing'.
Technics SL-1200 direct-drive turntables were first released in 1973, and were aimed at professional DJs on the developing club scene. Pairs of these decks, together with a mixer, became the industry standard tool of hip-hop and club DJs throughout the 1980s and 1990s. Model SL-1210 Mk2.
