Commentary
A full-auto player with a direct drive system.
The drive system is a direct drive system, and the drive motor is a 20 pole, 30 slot, supersaturated magnetic core type brushless motor.
In addition, a quartz-locked PLL servo system is adopted for the servo mechanism, and combined with a 1.9 kg turntable, high rotational accuracy is obtained.
A lightweight straight arm is used for the tone arm to suppress unwanted vibrations in the ultra-low range caused by warping or eccentricity of the record by moving fo and to improve traceability.
In addition, the arm has an anti-skating control function.
The full-auto mechanism uses a 2-motor system that uses a DC motor exclusively for driving the tone arm, and ensures smooth operation for each operation.
The head shell uses a carbon fiber head shell that suppresses resonance.
In addition, the MG-55, a MM type cartridge, is installed in the cartridge.
Electronic control feather touch type is adopted for the switches, and rotation speed, disc size, repeat, etc. can be switched.
The cabinet is made of BMC material, a high-density material with a large howling margin, reducing the influence of external vibration.
