Sony PS-LX2C is a fully automatic turntable system with a Magnedisc Servo System that monitors the speed of the turntable with great precision. It has a linear torque BSL (brushless and slotless) direct drive servo motor with a high signal-to-noise ratio. The low-mass tonearm and cartridge allow the stylus to track with greater accuracy. The Servo Lock indicator illuminates lighter when the turntable starts to rotate at nominal speed. Disc centering guides facilitate placing a 30 cm record over the center spindle.
