Commentary
Full auto-player capable of + / - 6% pitch control with quartz accuracy.
Adopting a unique Q. L. S. (quartz linear synthesizer) system, the pitch can be controlled continuously within ± 6% while maintaining rotational accuracy within ± 0.002% deviation due to quartz control.
An integrated structure D. D. turntable is used for the drive part.
A gimbal suspension bearing structure is adopted for the tone arm. By combining four bearings with a pivot and ball bearing, a high initial motion sensitivity of 7 mg or less in all directions is realized.
A plug-in connector type MM cartridge is mounted.
Conventional cartridges can also be used by replacing the head shell.
Equipped with a full automatic mechanism, it automatically detects the set record size, sets the rotation speed, and starts playing just by pressing the start button.
The cabinet is made of precision die-cast aluminum and the bottom base is made of TNRC, making it a double anti-vibration structure with excellent anti-vibration and vibration damping ratio and strong against external vibration.
