Technics SL-1300G ΔΣ-Drive Direct Drive Turntable
Turntable with a hi-fi design featuring ΔΣ-Drive, a new motor drive technology that delivers high rotational accuracy and low vibration. The turntable’s new motor, three-layer platter, and high-rigidity chassis ensure even higher sound quality.
The SL-1300G uses a coreless direct-drive motor with no iron core to eliminate 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.
The 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.
The tonearm uses a lightweight, rigid aluminum tube 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
