Commentary

This is a full auto player that uses an original integrated structure D. D. motor and acoustic material TNRC.

The B / FG method is used to detect the rotational speed of the motor, and a unique integrated structure D. D. motor is used, in which the rotating part of the motor is integrated with the turntable.

It is a double vibration isolation structure using TNRC, an acoustic material with excellent vibration absorption characteristics, for the cabinet and base by changing the vibration characteristics.
In addition, it is designed to minimize unnecessary resonance space as much as possible and to absorb vibration most effectively through thorough vibration analysis.

The bearing structure of the tone arm employs a high-sensitivity gimbal suspension system with an in-house high-precision pivot bearing. This enables horizontal and vertical rotation axes to intersect at a single point, achieving an initial motion sensitivity of 7 mg for both horizontal and vertical.

The cartridge is equipped with MM type cartridge (270C).
In this cartridge, a CKS magnet with excellent magnetic characteristics is directly connected to a high-strength aluminum alloy cantilever with excellent rigidity and light weight to reduce the effective mass of the vibrator, thereby obtaining flatter frequency characteristics.

Equipped with a memo repeat function.
