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.

Denon DP-60L (1980)


Quartz PLL Servo-Controlled Direct-Drive turntable (1980)
The DP-60L is an extremely versatile high quality quartz-lock controlled turntable system that meets the high standards demanded by today's sophisticatesd audiophiles. This DENON turntable featuring the DENON QUARTZ SYSTEM, is the ultimate in original design technology. And for added versatility, the lightweight (5,5 g) tonearm can be replaced with the universal S-type. The whisper-quiet AC servo motor combined with DENON's quartz-lock servo control, drives the turntable at previously unheard of limits of accuracy.


MAIN FEATURES
A no-contact end sensor auto-lift mechanism.
The lightweight straight tonearm makes full allowance for high-compliance certridge performance.
Integrated shell and universal cartridge adaptability through the replaceable universal S-type tonearm.
Ahigh-precision turntable speed control servo system that combines magnetic pulse and quartz lock systems for flawless two-way servo control.
Smooth, whisper-quiet AC servo motor.
Feather-touch black-lit control buttons.
Mirror finish, high-density Bubinga veneer laminated cabinet combines vibration resistance, solid weight and good looks.
