Technics SL-1200GR2 Direct Drive Turntable (Silver)

The first stage of Technics’ new generation of direct drive turntables with an improved motor-drive circuit centered on the newly developed ΔΣ-Drive (Delta Sigma Drive), the SL-1200GR2 is the new standard turntables, inviting more audio enthusiasts to enjoy music with the rich, robust sound of analog records.

New Motor-Drive System

The ΔΣ-Drive is a new system that applies Technics’ expertise in PWM signal processing. In addition to reducing high harmonics, the new drive suppresses vibrations from the motor for smoother, more accurate rotation, ensuring a rich reproduction of the music.

Coreless Direct-Drive Motor Achieving Stable Rotation

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.

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 aluminum die-cast to eliminate the unnecessary resonance that is otherwise relayed to the record, thereby producing clear sound. 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 aluminum pipe with excellent light weight and rigidity for the material of the tonearm pipe. 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.

Low-Noise Switching Circuit

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.

Two-layered Cabinet Construction

The SL-1200GR2 ensures high rigidity by using a body with a two-layered construction that solidly unifies the BMC and the aluminum die-cast chassis.

High-Quality Terminals

The turntable uses gold-plated phono terminals for detachable cables, while metal shielding construction inside the case reduces the effects of external noise.

High-dampening Silicone Insulators

For the insulators supporting the body, the SL-1200GR2 uses special silicon rubber that ensures high vibration damping characteristics and long-term reliability.
