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 Model 350

 AM/FM Multiplex Stereo Tuner Amplifier Solid State
With most of the same design and performance features of the larger Sansui 800, this model is the most complete receiver available anywhere under 50 watts. For better FM performance, it too, features an FET and 3-gang capacitor frontend. In addition to improved FM sensitivity and selectivity (S/N ratio of better than 50 dB), the Model 350's FM section provides channel separation of better than 30 dB.
At home within a wide 30 to 20,000 Hz power bandwidth, the 350 keeps distortion below a negligible 1% and features a damping factor of 34 at 8 ohms.
Other large receiver features include an ability to power up to two speaker systems, to operate off both 75 and 300 Ω antennas, and automatic FM mono stereo switching.
