The record player which adopted the direct-drive
The brushless DC servo motor of a direct-drive scheme which
drives a turntable directly is adopted as a drive motor.
brushless and DC servo scheme which controls a rotational frequency by work of
the electronic circuitry which consisted of a transistor and diode automatically
are adopted as roll control.
The tone arm part is improving trances
capacity by examining the form and the quality of the material of the bearing
part which influences a sensitivity greatly. Moreover, adoption of the hole
vacancy lightweight shell is raising the precision for carrying out.
original anti skating organization which combined the spring and the cam is
adopted as cancellation of an inside force. Furthermore, the stylus-force
tick-mark value serves as a scheme showing an anti skating bias value as it is, and it can adjust also in a record performance.
PC-330 which is
man-month type cartridge is adopted as a cartridge.
The double structure
cabinet which combined hard plywood and the metal base is adopted as a cabinet.
Moreover, the insulator which can be adjusted level is adopted and the
influence by the howling or an extraneous vibration is proposed.
change of a rotational frequency has adopted the electronic formula which can be
held only by constant switching of an electronic circuitry. furthermore -- while
supervising the stroboscope minced by the perimeter of the turntable -- 33 both
1 / 3 or 45rpm -- although -- it can tune independently finely by ±2% of within
Moreover, since the motor serves as a direct drive by a voltage
stabilizer, it does not need to exchange pulleys with the line frequency
(50Hz/60Hz) of a using region.
The arm elevation organization in which
neither a record nor its needle point is hurt is adopted.
which brought the operation function together in one panel is adopted.
The stroboscope light is carried.
The low capacity (loop station
connector) output code which can respond to 4ch play is adopted.
