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.

Technics SL-2000 DD

Technics SL-2000 "Black Beauty" Direct Drive Turntable

 The SL-2000 is designed for those who want direct drive performance at a moderate cost. This beauty is equipped with Technics famous brushless DC motor, which operates free from power line fluctuactions and trouble causing heat and hum. The absence of moving parts in the motor means better reliability and longer service life. Completely accurate platter speed is quaranteed by a One Chip IC servo control, a simple and compact unit equivalent to 78 electronic components. The result of all this precision is wow & flutter of only 0,045% (WRMS) and rumble 0f -70 dB (DIN B).
 A precisely manufactured tonearm ensures minimum tracking error and optimium mass distribution for high compliance cartridges. Clear and clean sound reproduction is assisted by the Insulation Fibre Board (IFB) and a newly developed insulator which effectively shields the motor and tonearm assembly from outside vibrations. The heavy zinc diecast tonearm base also works to prevent vibration and subsonic resonances.
 Other features include a fine-scale (increments of 2,5g) direct reading antiskating device, an illuminated stroboscope, independent pitch controls variable by up to 10%, viscous-damped cueing, aluminum diecast universal headshell, and detachable dust cover.
