TECHNICS SP-15

Second-hand, in good condition, it has a small scratch (see pictures). No original package. Equipped with Technics SH-15B3 base.

The Technics SP-15 is a direct-drive turntable that inherits the legacy of the SL-1300mk2 model, integrating cutting-edge technologies to deliver top-tier audio performance. This model allows precise pitch adjustment with 597 options, covering three speeds: 33 1/3, 45, and 78.26 RPM, with a variation of up to ±9.9% in 0.1% increments. One of the standout features of the Technics SP-15 is its ability to provide exceptional stability during playback.

The heteropole D.D. (Direct Drive) motor is designed to provide an impressive starting torque of 3 kg ・ cm, allowing the 2.7 kg platter to reach a constant speed in just 0.4 seconds. This is made possible by the power of the motor and the combined electronic and mechanical braking system, which allows the turntable to stop just as quickly.

To further optimize sound performance, the Technics SP-15 is equipped with an advanced damping system that reduces unwanted vibrations. The platter is treated with a special viscoelastic material applied to the bottom and outer circumference, effectively absorbing sound waves. Additionally, a vibration-absorbing rubber sheet inserted into the top of the platter forms a three-layer damping system that eliminates resonance and prevents any potential howl or distortion caused by external vibrations.

The cabinet is made from aluminum die-casting, a material known for its strength and precision in processing. The bottom base features a double anti-vibration structure made of TNRC, a material offering excellent damping and isolation from external vibrations. This design ensures that the sound produced by the turntable is free from distortion caused by mechanical interference.

For pitch control, the Technics SP-15 uses a highly integrated CMOS LSI (MN6042), with a circuit that includes over 3,000 electronic components, such as frequency division circuits (DN860), phase speed control (AN660), and motor control (AN640). These elements enable the turntable to maintain exceptional speed and platter stability control.

An innovative feature is the integration of the motor with the platter, eliminating the traditional separate system. This solution allows for direct and precise transmission of movement, reducing energy loss and improving overall performance. The F.G. detection system continuously monitors the rotational speed of the motor, ensuring consistent stability.

Finally, the Technics SP-15 is equipped with a high-efficiency pulse power supply circuit that optimizes the delivery of DC power, minimizing energy consumption while maintaining high performance.
