Commentary
Quartz D. D. player system with emphasis on basic performance.
425 kg ・ cm with 2.5 kg heavy duty turntable2It has excellent load fluctuation characteristics with no change in rotational speed even at the moment of inertia and 200g needle pressure. In addition, the drive section is equipped with a brushless DC motor with a starting torque of 1.5 kg ・ cm, and excellent characteristics are obtained by unique integrated structure D. D. and quartz control.
The tone arm is equipped with a high-sensitivity gimbal suspension tone arm. The high-precision bearing structure realizes an excellent initial motion sensitivity of less than 7 mg in all directions.
Equipped with a dynamic damping mechanism that greatly improves the low-frequency characteristics of the pickup.
By dividing the damping weight with a spring and controlling the resonance of the pickup system with silicon oil and damping cylinder, low frequency resonance is suppressed and cross modulation distortion is greatly reduced.
Equipped with an auto lift-up mechanism, the tone arm automatically rises when the performance is finished.
In addition, it uses an optical non-contact method with an optical sensor to detect the end of the record, and does not burden the arm or cartridge.
The head shell is equipped with 2 types, conventional type and plug-in connector (T4P).
The cabinet uses a particle board that is made of real wood and finely pulverized by a special manufacturing method and compressed to a high density.
In addition, the turntable bearing is equipped with anti-vibration measures such as increasing strength.
