Technics SL-1200

Commentary

This direct drive player system was developed as the prototype of the SL-1200 series which has been produced for more than 30 years.

The drive section employs an electronically controlled ultra-low-speed DC motor of the same specifications as the SL-1100. This eliminates the influence of power supply voltage and frequency fluctuations and provides stable rotation.
310 kg ・ cm due to large starting torque²The turntable is rotated at a constant speed of 1/2 rotation, and quick start is also possible by stopping the turntable by hand and starting it instantly.

Excellent performance is obtained by direct drive system without any reduction mechanism such as belt and idler.

A strobe is engraved on the edge of 45 ° inclination, and the rotation speed can be finely adjusted accurately by illumination of the illuminator.
Speed switching is electronic, and fine adjustment is possible within 10% range by 33 1/3 and 45 rpm alone.

A large dynamically balanced turntable 33 cm in diameter and 1.75 kg in weight has been adopted.

The tone arm uses a precision die-cast S-shaped pipe arm.

Uses a one touch rack-and-pinion type for 0 balance and needle pressure adjustment.

Anti-skating force control can be performed simply by setting the knob according to the needle pressure.

Equipped with an oil dump type arm lifter.

Universal head shell of gold-plated terminal is adopted to prevent contact failure.

Equipped with an insulator to prevent external vibration.

A low-capacity cord is used to support CD-4.

Dust cover is included.
