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.

Sansui 441

 IC-Equipped FM/AM Stereo Receiver

Sansui has a sound policy on tonal quality. And there's no better introduction to Sansui hi-fi excellence than the modestly-priced 441. production costs of this newly-developed stereo receiver have been trimmed by a Sansui-developed construction  techniquw called CBM (Circuit Board Module). This simplifies the use of high-density integrated circuits and other electronic advances to maintain truly musical dynamics and clean tonal response. Despite its agreeable price, it features a hybrid IC amplifier delivering stable, low-distortion power to either or both connected stereo speaker systems. Ics and MOS FET circuitry keep pinpoint FM/AM reception noise-free and sharp. Accurate tone controls a precise phono equalizer and all the input/output facilities needed to handle your turntable, tape deck and auxiliary source components are included.
There's more, too. And thanks to CBM, Sansui's critical policy of excellence is applied all along the line.
