Description
The improved motor-drive circuit centered 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 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.
Multi-Stage Silent Power Supply
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 SL-1200GR2 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.
In addition, one type of auxiliary weight comes included, and the cartridge can be swapped with a variety of other cartridges to match the music genre or feeling. (Applicable cartridge weight when using the supplied auxiliary weight: 10 – 16.4 g (not including the supplied head shell))
