Quartz Phase Locked Control D. D. player system developed by investing the development of SP-10mkII.

The quartz Phase Locked control method enables excellent rotation control by the phase control method using a crystal oscillator as a reference signal.

The motor is equipped with a 2.9 kg turntable (inertial mass of 360 kg ・ cm2) reaches constant speed rotation at 90 ° (1/4 rotation).

The tone arm uses a gimbal suspension system that realizes an initial motion sensitivity of 7 mg.
In addition, it has an arm height adjustment mechanism with an adjustment range of 6 mm.

Equipped with electronic brake mechanism.
