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-514 turntable

Specifically Designed for High-Anti-Howling

Reliable Auto-Return and Quick-Start Convenience

Precision Synchronous Motor

High-Sensitivity Tone Arm

AS in all other new Pioneer turntables, the PL-514 offers extremely high anti-howling characteristics. The kind of feedback or acoustic resonance caused by sound pressure from high-output speaker systems, for instance, is prevented from harming your music by a number of effective features. "Floor howling" - that caused by vibrations of structure-floors, shelves, desks, etc. - from speakers, are damped before they reach the tone arm and stylus. And they can never spoll the near-perfect operation of the synchronous motor to cause speed errors in the platter. A high-sensitivity tone arm, a noiseless belt-drive system, a convenient Quick -Start mechanism and Pioneer's time-tested Auto-Return arm device. They add up to one of the highest cost/performance ratios available in today's sophisticated turntables, and all are yours to enjoy in the Pioneer PL-514.

 


Tone Arm

Precision Ground Super-Hard carbon-Chromium Bearings in Tone Arm Support

Pioneer uses precision-ground bearings of extra hard carbon-chromium steel in the vertical bearing assembly for the tone arm support in the PL-514.  You enjoy unusually high tone arm sensitivity - that all-important factor in accurate record-groove tracing - not only when your turntable is new, but after years of use. The arm itself has a long effective tracking length (221 mm ), thanks to its gentle S-curve shape.
