Fusing Technics' traditional analogue and leading-edge digital technologies
 
Launched in 2016, the SL-1200G combined Technics‘ traditional analogue technology and advanced digital technology, while redesigning parts throughout. Its outstanding performance literally rocked the hi-fi market and redefined the reference for direct-drive turntables. Parts that were inherited from the SL-1200G were newly developed for the SL-1210GR, beginning with the coreless direct-drive motor and precise motor control technology that eliminated the cogging that originated from rotation irregularity, and including a low-vibration, high-rigidity platter and high-sensitivity tonearm. By these measures, the level of performance clearly outperforms the usual standards of its class. The SL-1210GR invites more audio enthusiasts to enjoy music with the rich, robust sound of analogue records.
Coreless Direct-Drive Motor Achieving Stable Rotation
In 1970, Technics commercialized the world‘s first direct-drive turntable, and the system took the world by storm. Unlike belt-drive and other systems, direct-drive systems rotate the motor at low speed and directly drive the platter, thus providing numerous advantages, such as the almost complete absence of degradation in S/N ratio due to motor vibration and deceleration mechanisms, as well as high reliability over a long period time because of not requiring parts replacement.
And in 2016, Technics developed the twin-rotor, surface-facing, coreless direct-drive motor with rotor magnets placed on both sides, thereby eliminating the rotation irregularity of the motor, referred to as "cogging," which was a unique issue for direct-drive systems. This motor was adopted for the SL-1200G, which once again drew a significant response in the hi-fi market. The SL-1210GR inherits the same design philosophy with the new development of a single-rotor, surface-facing, coreless direct-drive motor, resulting in the elimination of cogging.
 
High-precision Motor Control for Ideal Rotation Conditions
The rotation control, which verifies and corrects the precision of the motor, uses the latest motor control technology cultivated in the development of Blu-ray disc devices, just as that used by the SL-1200G. Sine waves stored in ROM are used for the control waveforms at constant speed, and this achieves smoother and more stable rotation compared with using the simple sine wave generation with an external coil as in the conventional SL-1200MK5. In addition, the electrical circuitry has had tuning performed so that the newly developed motor of the SL-1210GR achieves maximum performance. The starting torque achieves 2.2 kg x cm with only a single rotor. The same startup time of 0.7 s (at 33 1/3 rpm) as the SL-1200G has been achieved.
 
Pursuing Rigidity and Vibration Damping Characteristics
The platter achieves high rigidity and vibration damping characteristics by using a two-layer construction with deadening rubber applied to the entire rear surface of the aluminium die-cast to eliminate the unnecessary resonance that is otherwise relayed to the record, thereby producing clear sound.

To increase the inertial mass and reduce vibration, the shape of the aluminium die-cast portion was optimized by simulation. At 2.5 kg (including the rubber mat), the SL-1210GR platter is 0.8 kg heavier than that of the previous SL-1200MK5. Also, the back surface of the platter has strengthening ribs added to improve rigidity. Increasing the surface area of contact with the deadening rubber achieves damping characteristics that are more than twice those of the SL-1200MK5.
