Coreless Direct Drive Motor Achieves stable rotation Coreless Direct Drive Motor The high‐quality sound realised by the exceptional S/N ratio and high rotation accuracy of the direct drive system employed in Technics turntable products has captivated the hearts of audiophiles the world over. The SL‐1500C inherits the same high‐quality sound found in Technics’ high‐end turntable models. It uses a single‐rotor, coreless direct drive motor in which the stator has no core and eliminates the rotation irregularity called cogging. In this motor, the magnetic force of the rotor magnets was improved to the highest possible level, and the gap between the coreless stator and rotor magnets was optimised, thus achieving high torque performance equalling that of the SL‐1200MK5 while eliminating cogging. Furthermore, the motor control was Turntable Shaft optimised in accordance with the platter weight. As a result, the SL‐1500C has realised high rotation accuracy and high Rotor Yoke performance, and eliminated the need for parts replacement Magnet and maintenance. Another advantage of the direct drive Back Yoke Housing Shaft Bearing system is its long‐lasting, high reliability. Technical Information for Hi‐Fi Audio System...

Coreless Direct Drive Motor SL‐1200mk7/SL‐1500C Platter shape optimised by simulation High Accuracy Motor Control In the direct drive system, the motor is connected directly to the platter so that the motor rotation speed becomes the rotation speed of the phono record. Therefore, it is extremely important to control the drive motor’s rotation speed to ensure stability. The SL‐1500C utilises the latest motor control technology refined through the development of Blu‐ray disc products. Furthermore, the FG coil pattern of the full‐ circumference detection FG system was improved in precision to achieve more detailed measurement of platter rotation speed. SL‐1200mk5 Accurate sine wave output by the microcomputer is used as the control waveform for constant rotation speed operation. This sine wave is smoother than the simplified sine wave generated by the external coil used in the SL‐1200MK5, thus ensuring accurate motor control. The SL‐1500C also utilises the newest motor control technology refined through the development of Blu‐ray disc products. Furthermore, it incorporates technologies used in high‐end models to correct variations of characteristics in the parts of the motor drive circuit and magnetic circuit.

Turntable Platter Platter shape optimised by simulation Two-layer Structure with Improved Vibration Damping Performance The platter on which a vinyl record is placed features a two‐layer structure with deadening rubber on the entire back surface to eliminate unwanted resonance in the aluminium die‐cast platter. The platter offers high rigidity and outstanding vibration‐ damping characteristics to prevent harmful vibration from being transmitted to the record and delivers clear sound. To increase the inertial mass and minimise vibration, the shape of the aluminium die‐cast section was optimised through simulation. For extra rigidity, reinforcing ribs were added to the back side. The increased area of contact with the deadening rubber contributes to the outstanding vibration‐damping characteristic that is more than two times higher than that of the SL‐ 1200MK5. 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.22 0.24 0.26 0.28 0.3 ‐50 : 1500C ‐100 ︓1200MK5 ‐150...

Tonearm phono cartridge A Accurately reads signals from the groove on the record High Sensitive Tonearm The tonearm, which is responsible for accurately reading the signal by tracking the groove on the phono record, is a static‐balance universal S‐shape tonearm, another Technics tradition. The tonearm pipe is made of lightweight, high‐rigidity aluminium. The bearing section of the gimbal suspension construction tonearm consists of a machined housing and high‐precision bearing to provide high initial sensitivity. All in all, the tonearm accurately traces the groove on the record and reads the signal. High‐sound‐quality MM cartridge provided Phono Cartridge The supplied universal head shell is mounted with an Ortofon 2M RED cartridge. So, you can play a record immediately after purchasing the SL‐1500C. The tonearm height can be easily adjusted within a range of 6 mm to enable the use of various other phono cartridges. Using the auxiliary weight that comes with the product, a cartridge weighing 14.3 to 25.1 g (including the supplied head shell) can be used. Technical Information for Hi‐Fi Audio System...

Auto Lifter Function Equipped with an Auto Lifter Function That Allows You to Enjoy Playing Records More Comfortably When the tonearm reaches the end of the record, the Auto Lifter function automatically raises the cartridge. This prevents unnecessary wear on your valuable vinyl records and stylus. By embedding the Auto Lifter function in the base portion of the tonearm, it eliminates impacts to the tonearm. Due to a simple design that doesn’t use motor power, there is no electrical or vibrational impact and it will not prevent the movement of the tonearm. In response to requests from many users regarding the Auto Lifter function, a design that prioritizes sound quality was adopted. The functions required to playback records were kept to a bare minimum, achieving simple and easy‐to‐use operability. Technical Information for Hi‐Fi Audio System...

Built-in Phono Equalizer and Cartridge Connects to a variety of devices Built‐in Phono EQ The SL‐1500C has a built‐in phono equalizer amp compatible with MM cartridges so it can be connected to an audio product that does not have phono input terminals. The dedicated power supply for the phono equalizer is isolated from the power supply for the motor and control circuitry to reduce the effect of noise. Furthermore, the shield structure suppresses the effect of external noise. As a result, high‐purity signal amplification is realized. Using the SL‐1500C and the audio equipment you have, you can enjoy music from a vinyl record in high sound quality. Technical Information for Hi‐Fi Audio System...

Turntable Platter Cabinet featuring an anti‐vibration construction for thorough shut‐out of all vibrations High Rigidity Cabinet and High Damping Insulator The chassis, an essential part for reducing external vibrations, inherits the audio quality enhancement technology fostered through the development of high‐end turntables. The aluminium die‐cast chassis is rigidly integrated with a special material consisting of ABS mixed with glass fiber to achieve a two‐layer construction. The combination of this special high‐rigidity material and a metal chassis raised the rigidity and vibration‐damping performance to higher levels, realising a robust cabinet for beautiful sound reproduction. The insulator is comprised of a spring and rubber to provide optimal frequency characteristics. This not only assures high sound quality and superb howling resistance, but also effectively shuts out external vibrations under high sound level conditions.
