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 analogue records.
 
Fusing Technics’ traditional analog and digital technologies, the SL-1200GR2 is the new standard in direct drive turntable systems. With a revolutionary new drive control method for smooth, accurate rotational stability and a new power supply for an exceptionally low noise floor the new generation turntable outperforms the usual standards of its class, for rich, robust sounds and true high-fidelity listening.

High-rigidity body and high-damping silicon insulators for smooth sound and isolation from various vibrations
 
The First Stage of The New Generation of Technics’ Direct Drive Turntables
Since inventing the world’s first direct drive turntable, Technics has continued to work to improve sound quality. It has now developed the ΔΣ-Drive, which suppresses minute vibrations from the motor and improves the electromagnetic conversion accuracy of the cartridge. The first stage of direct drive turntable systems featuring this technology is the SL-1200GR2.
 
New Motor-Drive System, ΔΣ-Drive (DeltaSigma Drive)
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.
 
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)
