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.

JVC JL-B41 turntable


Direct drive system developed intorducing vibration free  and no-resonance design technology.
The Tone-arm design with a low center of gravity  and applied Anti-vibration measures. Vibration damping materials are applied to the inside of the pipe and the precision bearing part, and a rubber isolation is used for rear arm part support.
