What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Pioneer PL-12D

With this well-made stereo turntable, Pioneer proves once again that quality and parcticality are synonymous. The budget-prieced PL-12D gives you more for your stereo investment than you'd ever expect. A fine synchronous motor that helps cut out audible wow and flutter. An extremely steady belt-drive. An anti-skating control to lessen distortion. A cueing device with simultaneous movement with the start lever. And a beautifully-balanced S-shaped tonearm with plug -in type lightweight head-shell. For the man about to make his first investment into stereo components, the PL-12D becomes more than a budget investment but a truly professional turntable that will serve him well for many years of quality sound reproduction.
 Drive Motor Section
The Pl-12D employs a 4-pole synchronous motor and a belt-drive system to ensure stable rotation of the turntable platter that is free from line voltage fluctuation. The synchronous motor is much like the motors usually used only in expensive turntables, and is the quietest that you can own. It gives you an extremely high Signal-to-Noise ratio, extremely low wow and flutter, and helps cut down on irritating motor vibration

Tonearm Section
The tonearm of the PL-12D is the static-balanced, S-shaped type that uses a super hard alloy material aat the pivot point of its arm, thereby assuring sesnsitive, stable tracking at all times. The counter weight of the tone arm is the stylus pressure direct reading type that gives easy weight adjustment when cartridge-changing is necessary. Then there is a lightweight plug-in type headshell so that you may use a cartridge with its stylus pressure from 0,75 grams. To cut down on distortion, the PL-12D has an anti-skating control to suppress the harmful inward force of the stylus.

Other Distinctive features
The cueing control an oil-damped arm elevation device, is connected to the start lever and helpd prevent damage to your stylus or your record usually caused by misoperation. There is a stylus position gauge to facilitate easy installation of your favorite cartridge. And Pioneere used aluminum foil on the inner part of the Pl-12D's wooden cabinet to prevent external noise often caused by yoour amplifier or other equipment placed near the turntable. The cabinet itself elegantly styled is the spring-suspension type and designed to cope with external vibraation. The dust cover of the Pl-12D is hinged in the free-stop manner, permitting you to leaave it at rest at any angle you choose.
