Description
Technics SL1200GR2 turntable
Technics SL1200GR2 SL1200 GR2 is an instant classic, recognisable the world over. This high-end version is beautifully built and precision engineered.
The improved motor-drive circuit centred on the newly developed ΔΣ-Drive (Delta Sigma Drive) thoroughly suppresses any minute vibrations generated from the motor. This is the first stage of Technics’ new generation of direct drive turntables that aim for further improvements in sound quality.
New Motor-Drive System, ΔΣ-Drive (Delta Sigma Drive)
The ΔΣ-Drive (Delta Sigma Drive) — A New Interpretation of Analogue Vinyl Sounds
In 1970, Technics developed the world’s first direct drive turntable.
Direct drive turntable systems helped to significantly improve issues with previous turntables, such as S/N ratios, and wow and flutter. Used by broadcasting stations for their outstanding performance and reliability, these turntables came to dominate the industry. In 2016, Technics developed the coreless direct drive motor, which helped to eliminate a mechanical issue known as cogging. Combining this motor with the latest digital rotational control technologies helped to realise a dramatic improvement in sound quality.
Technics has continued to engage in R&D to further improve the audio quality of analogue vinyl and better draw out the charms of the music, and as a result has successfully developed the ΔΣ-Drive, which boasts significant advancements over previous direct drives. This development marks the next generation of Technics’ direct drive turntable systems.
The First Stage of The New Generation of Technics’ Direct Drive Turntables
Coreless Direct Drive Motor Achieving Stable Rotation
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-1200GR2 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.
Low-Noise Switching Circuit
A switching frequency of above 100 kHz limits the impact of noise on the music playback bandwidth.
Current Injection Active Noise Cancelling
Pursuing Rigidity and Vibration Damping Characteristics
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 Technics SL1200GR2 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.
Tonearm Achieving High Initial-Motion Sensitivity
With its gimbal suspension construction, the tonearm bearing section uses a cut-processed housing that employs high-precision bearings, as in the SL-1200G and SL-1200GR. The high initial-motion sensitivity of 5 mg 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.
