Pioneer PL-1150

Commentary

A direct drive record player with a hole motor.

A brushless DC servo DD motor is used as the drive motor.
This motor uses a Hall element, which converts changes in magnetic field into changes in current, to switch the magnetic pole that drives the motor. This eliminates vibration and wear caused by friction, and realizes high S/N and durability.
An electronic circuit automatically controls the DC motor so as to keep the rotational speed constant, thereby achieving stable rotation.

The S-shaped tone arm with high sensitivity design is used for the tone arm.
In addition to reducing the weight of the arm itself, the PL-1150 uses angular contact bearings for the horizontal and vertical rotating parts of the bearing section to increase the tracing capability at light needle pressure.

MM type cartridge PC-131 is used for the cartridge.
This cartridge is equipped with an independent magnetic circuit for the left and right channels to generate power, and has excellent crosstalk characteristics.

The cabinet uses 3 mm thick aluminum arm panels based on high strength and high specific gravity (1.5) mineral solid.
We have also adopted a new type of insulator that is resistant to external shocks and vibrations. This insulator is made of a combination of butyl rubber and natural rubber and absorbs shocks by applying air pressure.

Equipped with a strobe, the rotational speed can be finely adjusted within ± 2%.

Butyl rubber is used for the turntable seat.

Equipped with anti-skating mechanism, lateral balancer, arm elevation mechanism, and needle pressure direct reading weight.

Equipped with a head shell stand.
