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.

Sonab 67S

 Many people maintains that the turntable, after the loudspeakers, is the most important part of stereo equipment.
If you have a bad turntable, neither amplifier non loudspeakers will help. It will sound bad. In addition, an inferior turntable will ruin records. Stereo records of great value can quickly be ruined by a poor stylus or turntable.
We have one turntable of our own, the Sonab 67S.
It has all necessary technical features as well as highly distinctive styling. It is easy to work and is effectively isolated from vibrations.
Sonab 67S has a precision balanced tone-arm with adjustable antiskating.
