They introduced the first direct-drive system in 1969 (the SP-10) for professional use and in 1971 (SL-1100) for the consummer market.
From then on catered for the budget-consumer market, the serious audiophile as well as the broadcast industry.
The best known model became the SL-1200Mk2 which became the standard turntable first for Hip Hop and then for all other DJs.
