Technics new SL-1200GR and SL-1210GR turntables open a new chapter
Technics has unveiled the new Grand Class SL-1210GR (black) Direct-Drive Turntable System, joining the SL1200GR (silver) edition that was announced earlier this year.Both models inherit technology from the SL-1200G, which was developed as a reference direct-drive turntable for the next generation. On top of these features, the latest models offer new materials and technical design, making them more affordable
The incarnation of this turntable, the SL-1200GR (silver) and SL-1210GR (black), will be available from April 2017 onwards. As customers have come to expect from Technics, the SL-1200GR and SL-1210GR models make no compromise on sound quality, says Technics. At the same time, these newcomers also provide all the functions that made their iconic predecessor so popular among DJs: its durability, shock resistance, reliable direct drive and adjustable rotation speed. The latest models also come with new materials and a novel overall technical design.
"The SL-1200GR and SL-1210GR combine the best of both worlds," says Michiko Ogawa, Director Technics at Panasonic. "We are sure both models will fulfill the expectations of Technics fans around the globe. Our objective was to extend our top range for audio enthusiasts as well as professional DJs."
Launched in 2016, the SL-1200G combined Technics‘ traditional analogue technology with advanced digital technology. Parts from the SL-1200G were newly developed to create the SL-1200GR and the SL-1210GR, such as the coreless direct-drive motor and precise motor control technology, high-rigidity platter and high-sensitivity tonearm.
Unlike belt-drive and other systems, direct-drive systems rotate the motor at low speed and directly drive the platter. This concept provides some 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. The SL-1200GR/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.
The SL-1200GR/SL-1210GR’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/SL-1210GR 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 aluminium 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 aluminium die-cast portion was optimised by simulation. At 2.5kg (including the rubber mat), the SL-1200GR/SL-1210GR 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, according to the manufacturer
The tonearm inherited by Technics is the traditionally used static-balance universal S-shaped tonearm, employing aluminium for light weight and rigidity, for the material of the tonearm pipe. With its gimbal suspension construction, the tonearm bearing section of the SL-1200GR/SL-1210GR 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 hand.
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.
The SL-1200GR/SL-1210GR ensures high-rigidity by using a body with a two-layered construction solidly unifying the BMC and the aluminium die-cast chassis.
For the insulators supporting the body, as with the SL-1200G, the SL-1200GR/SL-1210GR uses special silicon rubber that ensures both high vibration damping characteristics and long-term reliability. Vibration in the horizontal direction is absorbed by reinforcement with cylindrical tubes using microcell polymers. While inheriting the technology of the SL-1200G, the insulators have been modified to specifically suit the characteristics of the SL-1200GR/SL-1210GR.
The new turntables are available in the UK from April and both will be priced at £1,299.
