Technics SL-1210GR2

The Next Generation of Direct Drive Turntable Systems

The improved motor-drive circuit centered on the newly developed 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.

Multi-Stage Silent Power Supply

Low-Noise Switching Circuit

Technics SL-1210GR2 use of a high-speed switching power supply ensures a stable supply capacity and less ripple and humming.

Applying a switching power supply to a turntable eliminates the need for a large transformer and countermeasures for the ensuing mechanical vibrations.

A switching frequency of above 100 kHz limits the impact of noise on the music playback bandwidth.

Current Injection Active Noise Cancelling

This technology combines a noise detection device with an error amplifier.

It detects residual noise in the power supply and applies an inverse phase current to remove noise components.

It removes low frequency noise more effectively than a regulator to ensure a more ideal power supply

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 optimised by simulation.

At 2.5 kg (including the rubber mat), the Technics SL-1210GR2 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

The tonearm tracks the rotation of the record and enables reading with high precision, and the tonearm inherited by Technics is the traditionally used static-balance universal S-shaped tonearm, employing an aluminium pipe with excellent light weight and rigidity for the material of the tonearm pipe.

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))
