Technics SL-1200GR Direct Drive Turntable.

The direct-drive turntable invented by Technics is still highly acclaimed by audiophiles and DJs in the form of the SL-1200 Series, and there have been many requests to revive the turntable system. As such, Technics decided to develop a new system for Hi-Fi use. Technics provide an outline of their intent in this development.
Unlike belt-drive and other systems, direct-drive systems rotate the motor at low speed and directly drive the platter. This concept provides 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 of time because of not requiring parts replacement.
In 2016, Technics developed the twin-rotor, surface-facing, coreless direct-drive motor with rotor magnets placed on both sides, 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-1200GR 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.
The SL-1200GR’s rotation control, which verifies and corrects the precision of the motor, uses the latest motor control technology cultivated in the development of Blu-ray devices, just as that used by the SL-1200G. In addition, the electrical circuitry has been tuned to ensure the newly developed motor of the SL-1200GR achieves maximum performance.
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 aluminum die-cast. This eliminates the unnecessary resonance that is otherwise relayed to the record, thereby producing clear sound.
To increase the inertial mass and to reduce vibration, the shape of the aluminum die-cast portion was optimised by simulation. At 2.5kg (including the rubber mat), the SL-1200GR platter is 0.8kg heavier than that of the previous SL-1200MK5. Also, the back surface of the platter features strengthening ribs to improve rigidity. Increasing the surface area of contact with the deadening rubber achieves damping characteristics that are more than twice as good as those of the SL-1200MK5.
The tonearm tracks the rotation of the record and enables reading with high precision. The tonearm inherited by Technics is the traditionally used static-balance universal S-shaped tonearm, employing an aluminum pipe with excellent light weight and rigidity for the material of the tonearm pipe.
With its gimbal suspension construction, the tonearm bearing section of the SL-1200GR uses a cut-processed housing that employs high-precision bearings, as in the SL-1200G. The high initial-motion sensitivity of 5mg or less is achieved through manual assembly and adjustment by skilled Japanese artisans. This enables the grooves etched into the records to be accurately traced.
Gold-plated phono terminals and ground terminals for detachable cables are provided below the tonearm, so a wide variety of cables can be selected. Also, the use of metal shielding construction inside the case reduces the effects of external noise.
