Commentary
A record player with a belt drive system.
The drive system uses a belt drive system with a 4-pole synchronous motor. In addition, the turntable, rotating shaft, and bearing are carefully finished with an automatic precision machine to improve accuracy.
In addition, the belt that transmits the rotation of the motor uses polyurethane with a precision finish.
For the tone arm, S-shaped pipe arm which can deal with 4 ch reproduction and light needle pressure performance is adopted.
The center of gravity is designed to be low in order to increase the tracing capability. In addition, it is equipped with an anti-skating mechanism that can obtain an ideal value for canceling the inside force simply by setting the scale according to the applied needle pressure.
Other mechanisms such as oil dump type arm elevation linked to the start lever are also adopted.
In order to suppress howling, we have adopted a cabinet with a strong structure with large weight and mass.
The cartridge is equipped with MM type cartridge PC 110.
Equipped with a checker that can adjust the overhang when replacing the cartridge.
Uses a low-capacity (LSC) code capable of 4-ch playback.
Uses a free stop hinge that can stop the hood at any angle.
