Coreless Direct Drive Motor
Achieving Stable Rotation
In the SL-1300G, the use of a coreless direct-drive motor with no iron core eliminates uneven rotation of the turntable known as cogging. Also, the twin-rotor construction reduces the bearing load while maintaining high torque, and reduces minute vibrations during rotation. Furthermore, the SL 1300G’s motor was redesigned to eliminate subtle vibrations that could affect sound quality. To improve rigidity, the same reinforcement pattern as the Reference Class SL-1000R/SP 10R was used for the coil mounting base.

Motor-Drive System, 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. In addition to reducing harmonics, the drive suppresses vibrations from the motor for smoother, more accurate rotation, ensuring a rich reproduction of the music.

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.

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.

Tonearm Achieving High Initial Motion
Sensitivity
The tonearm, a crucial component for precise reading, tracks the record’s rotation. Inherited from Technics, it employs a lightweight, rigid aluminum pipe in the traditional static-balance universal S-shape. Featuring a gimbal suspension and high-precision bearing, it achieves high initial-motion sensitivity through manual assembly by skilled Japanese artisans. This meticulous construction ensures accurate tracing of record grooves. Plus, it includes an auxiliary weight, providing flexibility for a variety of pickup cartridges.

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.

The SL-1300G ensures high rigidity by using a body with a two-layered construction that solidly unifies the BMC and the aluminum die-cast chassis. Reinforcing ribs have been added between the motor/tone arm on the top panel. This improves rigidity and vibration damping characteristics.
