Technics - Grand Class Direct Drive Turntable II - Black
The first stage of Technics’ next generation of direct drive turntables with an improved motor-drive circuit centered on the ΔΣ-Drive (Delta Sigma Drive), the SL-1210GR2 invites more audio enthusiasts to enjoy music with the rich, robust sound of analog records. 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 Technics Grand Class SL-1210GR2.
Motor-drive system
The ΔΣ-Drive (Delta Sigma Drive) is a system that applies Technics’ expertise in PWM signal processing. In addition to reducing high harmonics, the 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
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.
Low noise switching circuit
Use of a high-speed switching power supply ensures a stable supply capacity and less ripple and humming. The switching frequency of above 100 kHz limits the impact of noise on the music playback bandwidth.
Current injection active noise cancelling
Combining a noise detection device with an error amplifier, noise cancelling technology 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
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. Optimized shape of the aluminum die-cast.
Tonearm achieving high initial-motion sensitivity
High-precision tonearm tracking of the rotation of the record. Static-balance universal S-shaped tonearm.
Two-layered cabinet construction
The SL-1210GR2 ensures high rigidity by using a body with a two-layered construction that solidly unifies the BMC and the aluminium die-cast chassis.
High-dampening silicone insulators
For the insulators supporting the body, the SL-1210GR2 uses special silicon rubber that ensures high vibration damping characteristics and long-term reliability.
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.
