Lo-D PS-44

Commentary

This manual player system uses a direct drive motor.

The drive section uses a direct drive system that employs an 8-pole 24-slot non-commutator DC servo motor.
In addition, it is equipped with a DC servo mechanism, and by controlling slight rotational deviation, accurate rotational speed is maintained regardless of fluctuation of power supply voltage.

An electronic control system is used for speed switching. The rotational speed can be finely adjusted within ± 3%, and strobe and neon lamps installed on the periphery of the turntable are mounted.
The operation part is concentrated on the control panel. Moreover, the power switch and the number of revolutions are changed by one lever type to improve operability.

A static balanced S-shaped tone arm is used for the tone arm, allowing direct needle pressure reading and head shell exchange.
In addition, since it uses a low-capacity output code, it is possible to play discrete 4 ch records by changing to a cartridge for CD-4.

Uses a VM (vertical magnet) type cartridge.
Since this cartridge has separate power generating magnets for the left and right channels, it has good crosstalk characteristics. In addition, it has excellent follow-up capability of the needle tip and has characteristics such as reducing distortion.

As a countermeasure against howling, we have adopted a cabinet with a large howling margin and a large insulator. In addition, rubber vibration isolator is used for the arm mounting part.

Uses a dust cover that uses a detachable auto hinge.

Equipped with anti-skating mechanism and oil dump-type arm lifter.
