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.

Sony leadership in every aspect of audio and video reproduction is legendary. That leadership is no accident, nor is it recent. It arises from three sources. First, the vast Sony research and engineering facilities, among the most sophisticated in the world. Second, a commitment to a "total system technology" in the design of all our products. And third, a commitment to translating this approach into instruments for the home that incorporate advanced technology at a cost within the reach of the user.

All vital component circuit elements are manufactured in our own plants, according to exacting tolerances and stringent quality control. Our concern with quality extends to human engineering and painstaking attention to detail, including precision finishing of controls. With every Sony component, there's a touch of luxury and a special  degree of convenience.

When it comes to testing component performance, the Sony standard is also high. And so are performance specifications, even though we quote them conservatively. In fact  it's hard to find a Sony component that won't surpass its rated performance specs.
