Description
 
The record player which adopted the direct-drive scheme.
There were two kinds such as PL-1100 of rosewood finish and PL-1100of white oak tone design D.

With the direct-drive scheme which carries out the direct drive of the turntable, the oscillation by the high velocity revolution of the rotation unevenness which comes from a propagation system, or a motor is suppressed.
Moreover, it has prevented controlling automatically the rotational frequency once set up by work of an electronic circuitry, and deviation producing it in a variation of an off-site temperature or supply voltage. Furthermore, since the drive power source of the motor is changed into the direct current by the built-in voltage stabilizer, regardless of a line frequency, its rotational frequency is constant.

The tone arm part has heightened trances capacity by performing precise polish finish in a bearing part.
Furthermore, since it has designed so that the centroid of the tone arm itself may become low, the sound track is improving trances capacity, such as complicated 4ch record.

It reinforced in the cabinet and the ill effect by an internal oscillation or an extraneous vibration is prevented by using special rubber for an insulator.

The original anti skating organization which combined the cam and the spring is adopted.
Moreover, in order to prevent damaging a record and the needle point, you carry the arm elevation organization and are making it the on-off control lever of a turntable rotation interlocked with.

The velocity change of a pure electronic formula is adopted, and also the stroboscope which can tune a velocity finely is carried by ±2% of within the limits.

The stroboscope light which illuminates the stroboscope minced by the perimeter of the turntable is carried.

PC-110 which is man-month type cartridge is carried in the cartridge.
Moreover, the plug-in type is adopted as a head shell.
