Commentary
A full auto player equipped with a large insulator and anti-skating mechanism.
If you specify the record size, it is equipped with a full automatic mechanism that starts playing automatically only by operating the operation lever.
The drive section uses a condenser phase shifted 16-pole synchronous motor. Since the motor is driven at 10 times the rotational speed of the turntable, vibration of the motor is reduced and a high S / N ratio is obtained.
An independent gear motor is used for the full automatic mechanism to prevent the automatic mechanism from adversely affecting constant speed rotation.
The tone arm is equipped with a dial operation type anti-skating mechanism to prevent the sliding of the arm and obtain a well-balanced tracing capability.
In addition, S-shaped low center of gravity tone arm is adopted for the arm, and MM type cartridge is mounted.
The balance weight uses a precision direct reading type of 0.2g unit.
It uses a low-capacity output cord and the same cartridge body as the CD-4 cartridge, and is compatible with CD-4 by changing the needle tip.
In order to prevent howling, we have adopted a specially designed insulator combined with air suspension.
It uses an oil dump type arm lifter that does not damage the needle tip or record board.
Dust cover with detachable auto hinge is adopted.
