Description
 
A DC servo DD motor and the record player using a high-sensitivity S character type pipe arm.
There were two kinds, PL-1400 the cartridge was attached to, and PL-1400C to which a cartridge is not attached.

The actuator has adopted the direct-drive scheme and is driving the high heavy weight class turntable of a flywheel effect using a super-low-speed brushless DC servo motor on the motor.

The pure electronic formula control circuit which consisted of a transistor and diode is adopted as a control circuit.
The automatic control (servo) of the rotational frequency which this set up once was carried out, and the fixed rotation has been obtained regardless of the variation of an off-site temperature or supply voltage.
It is 33, looking at the stroboscope minced by the turntable for the change of a velocity with the pure electronic formula which can be held by the constant change of an electronic circuitry. 1 / 3 or 45rpm all can perform a velocity fine tune independently in ±2% of within the limits. Moreover, since AC power supply is changed into a direct current by a voltage stabilizer and the motor is driven, there is no time and effort of exchanging pulleys for every line frequency.

S character type tone arm of a new-installation meter is adopted as a tone arm.
The cartridge to Self-weights 4g-32g is attached without a sub wait, and the difference signal component of a very light stylus-force performance or a discrete 4ch scheme which is 0.5g can also be traced.

Moreover, a head shell gives a rubber cushion specially and is reducing a vibration and modulation distortion with the lightweight type.

The cabinet is the vibration proof strengthening cabinet made into the double structure combining the metal base and native wood. This reduces an extraneous vibration and the oscillation from a floor, and the howling is suppressed.
Moreover, the large-sized insulator which can adjust the degree of level of the main unit of a player is adopted.

PC-330E which is man-month type cartridge is attached to PL-1400.
A 0.2x0.7mil ellipse type electric-contact-point diamond stylus is adopted as the needle point, and the tone-quality modification is aimed at by the weight saving (effective mass of 0.55mg) of this and vibration system.
Moreover, a perpendicularity and a horizontal can also trace the perpendicular swing of a matrix 4ch record by equal compliance.
