The Latest Coreless Direct Drive Motor Achieves High-precision Stable Rotation

The technologies acquired through the development of the SL-1200 Series and the high-end SL-1000R model were lavishly inserted into the motor drive unit, a key part of the turntable. The motor exclusively tunes the single-rotor, coreless direct drive motor adopted by the SL-1200GR in order to read the high rotation accuracy and high-precision signals of the record. Optimal motor control is conducted for the inertial mass of the two-layer structure platter on which the vinyl record is placed with deadening rubber on the entire back surface to eliminate unwanted resonance in the aluminium die-cast platter to eliminate the rotation irregularity called cogging. The aluminium die-cast chassis is rigidly integrated with a special material consisting of ABS mixed with glass fiber to achieve a two-layer construction. The insulator is comprised of a spring and rubber to provide optimal vibration-damping characteristics. The tonearm is a static-balance universal S-shape tonearm, another Technics tradition. By adopting a high-precision bearing using the same gimbal suspension construction and machined housing as the SL-1200 Series, high initial sensitivity is achieved. In addition, reliability has been improved by incorporating a removable power cable and gold-plated terminals, which have less sound quality degradation, for the PHONO and LINE terminals.
