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.

Optonica SM-105H


Optonica SM-105H
Straight DC Stereo Integrated Amplifier with Fully Electronic Control System

This perfectly "straight" amp is a result of Optonica's efforts to provide a fully digital system based on a lead-less and contact-less design. A combination of fully direct-coupled amplifier circuitry and fully electronic controls for tone, volume and balance completely eliminated the use of lead wires to improve frequency response. Conventional mechanical controls were replaced with electronic circuitry to eliminate contacts. Microcomputer-controlled circuitry splits up the signal to ensure more precise tone control and offer a wider dynamic range, better Signal-to-Noise ratio, lower distortion and greater durability.
A full remote control system, unique graphic displays and an innovative sound memory system were added to match the outstanding performance of this amp.
