Coreless Direct Drive Motor Achieving Stable Rotation

The SL-1200GME/1210GME features a coreless direct-drive motor that eliminates cogging for smooth rotation. Its twin-rotor construction maintains high torque while reducing bearing load and minute vibrations. The coil mounting base uses the same reinforcement pattern as the Reference Class SL-1000R/SP-10R for enhanced rigidity.

Upgraded ΔΣ-Drive (Delta Sigma Drive)

Unlock a realm of audio precision with the ΔΣ-Drive – a state-of-the-art system harnessing Technics’ expertise in PWM signal processing. The SL 1200GME/1210GME expands the PWM carrier frequency from around 2 kHz to over 20 kHz, reducing audible noise and further suppressing micro-vibrations.

Vibration Resistance Design

Three-layered Turntable Platter

The turntable has a three-layered construction with a rigidly combined brass and aluminium die-cast platter. With a deadening rubber covering its entire rear surface to eliminate unnecessary resonance, thereby achieving high rigidity and vibration damping. This delivers smooth rotational stability and inertial mass surpassing the SP-10MK2, the direct-drive turntable standard used by broadcast stations worldwide, as well as having more than twice the inertial mass of the SL-1200MK5.

High-Level Balance Adjustment

When the weight distribution of the turntable is uneven, excess vibration or noise occurs during rotation, which causes degradation in sound quality. Therefore, the balance of the turntable is adjusted at the factory by using specialized high-precision balance adjustment equipment for each and every item after the turntable is assembled. Turntables that have undergone adjustment are labelled with a sticker reading “BALANCED” to indicate that adjustment has been done.

Four-Layered Cabinet Construction

A hairline-processed, 10-mm-thick top panel of immaculate aluminum has been added to the previous three-layered construction of aluminum die-cast, BMC, and heavyweight-class rubber on the SL-1200MK5. This four-layered construction combines high rigidity with a high-quality finish and feel.

Insulator

A newly developed zinc insulator using αGEL™ gelatinous material with excellent shock absorption, providing high vibration damping and minimizing feedback.

Tonearm

The tonearm uses lightweight magnesium with cold drawing for high precision. High initial-motion sensitivity is achieved through Technics’ gimbal suspension construction and high-precision bearings.

Low Noise Switching Circuit

High-speed switching power supply over 100kHz ensures stable output, low ripple and reduced vibration.

Current Injection Active Noise Cancelling

Combined noise detection and error amp technology cancels residual noise via inverse current, outperforming regulators.

Upgraded ΔΣ-Drive (Delta Sigma Drive)

ΔΣ-Drive boosts PWM from 2kHz to 20kHz+, cutting noise and micro-vibrations for precise audio playback.

Pursuing the Ideal Circuit Layout

To improve board rigidity and layout, a four-layer PCB separates power and ground lines for motor, digital, and LED circuits.

Multi-Stage Silent Power Supply

The SL-1200GME/SL-1210GME features the Multi-Stage Silent Power Supply, integrating a low-noise switching circuit and a noise-cancelling circuit.
