Description
 
The manual scheme player system which adopted the direct drive motor.

The direct-drive scheme which adopted the non-commutator DC servo motor of 8 pole 24 slot is adopted as an actuator.
Moreover, DC servo mechanism which controls slight rotation deflection and is maintained at an exact rotational frequency regardless of a variation of supply voltage is carried.

The electronic control scheme is adopted as a velocity switching. Moreover, a fine tune of a rotational frequency is possible by the stroboscope and neon glow lamp which were formed in the perimeter of the turntable by ±3% of within the limits.
The intensive placement of these control units is carried out at the operator's paneloperator control panel, and, moreover, the power switch and the rotational frequency change have adopted the one lever type.

Static balance type S character type tone arm is adopted as a tone arm, and a stylus-force Direct reading and a head shell switching are possible.

Moreover, since output code serves as low capacity, a performance of a discrete 4ch record is possible for it by exchanging for the cartridge for compact-disk-4.

The VM (vertical magnet) type cartridge is adopted as a cartridge.
Since this cartridge has a separate magnet for a generation of electrical energy in the right and left ch, a crosstalk property is good, and also the flattery nature of the needle point is also excellent, and it has the property of decreasing distortion.

A large-sized insulator is adopted as the large cabinet of a howling margin, a rubber vibration insulator is adopted as an arm attachment, and it is considered as the measure against a howling.

The book jacket which uses the auto hinge which can be detached and attached is adopted.

The anti skate organization and the oil dumping type arm lifter are carried.
