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-71 turntable

Direct Drive System
No belt or idlers. The DC servo motor drives the platter directly, resulting in lowest possible vibrations transmitted to the tonearm. the result is a new height of turntable performance plenty for the most demanding audio enthusiast.

Electronic Servo Control
Turntable revolution speed is affected by many factors, including ambient room temperature, etc. which cannot be predicted or corrected by motor performance alone. this electronic circuit comes into play at the touch of a button, letting you adjust the speed ±2% during either 33-1/3 or 45 rpm play.
Precision Tracking Sensitive Anti-Skating System
Playing 4-channel records requires extra tonearm precision, and the PL-71 delivers. Not on;y with an exactly-balanced . the result is stable tracking over every part of the record for brilliant response from the first note to the last.

Convenient Auxiliary Features
The tonearm is raised and lowered by Arm Elevetor, saving both stylus and record wear. the stylus overhange can be adjusted precisely with thw overhang gauge. The stylus overhang can be adjusted precisely with the overhang gauge. the semitransparent dust cover is held by spring-loaded hinges and can be arrested in any desired position. If desired, it can be removed altogether.
Eye-Appeal Design
The cabinet is set off the natural beauty of selected walnut, with a smart black base plate. All controls are grouped on the right  for easy one-hand operation
