Commentary
The turntable was developed not only from audio technology but also from comprehensive research on basic physics, mechanical engineering, materials engineering, etc.
The bearings and turntables are made of military-standard materials that require strict accuracy and reliability.
The weight of the turntable is increased by adopting a lead sandwich structure in the outer peripheral part on the back side. The rotational inertia is increased while suppressing the resonance of the turntable itself, and a stable rotational force is obtained. The surface that touches the record is tapered by 1 ° in a dish-like shape, and the record and turntable are perfectly adhered by using the attached stabilizer.
In addition, the center of gravity of the player is aligned with the middle point of the turntable, which is the center of rotation, and extremely stable rotational performance is obtained.
The drive section is a belt drive system using a 24-pole hysteresis motor, and the rotation speed is changed by changing the belt.
We do not employ a speed detection mechanism using a servo circuit based on the idea that it is impossible to detect instantaneous speed and correct its error at the same time in a super-instantaneous manner. Rather, it may cause harmonic modulation relative to the corrected signal.
A unique shock absorber, Solbotane Polymer, is used throughout the system. It combines spring and shock absorber properties to absorb 95% of the impact received.
The legs are 3-point support system by this solbotane.
The cabinet portion of the 775 sm is usually black finished on the model.
In addition, there were 2 kinds of variations of walnut and oak as a special version.
