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 300

 AM/FM Multiplex Stereo Tuner Amplifier
You are loking at the most practical solid state stereo receiver on the market today. In design, performance and ease of operation, the Sansui 300 is without peer in the 36 watt class. It offers a modern black face window panel with a wide, linear scale FM tuning dial that is as functional as it is attractive. It boasts a new FET front-end with 5-stage IF amplifier for top FM sensitivity and selectivity. A wide 30 to 25,000 Hz power bandwidth (IHF) and a total marmonic distortion of less than 1% at rated output. A hum and noise figure of better than 65 dB at the phono input. And many other performance figures you'd only expect to find on receivers costing twice as much. In operating ease, it features conveniently arranged controls, the latest one-touch antenna and speaker terminals, automatic stereo switching and is able to work off both 300 and 75 Ω antennas. But it is in the field of FM reception that the Sansui 300 really shines. A new type of noise canceler that eliminates noise without weakening FM program high frequency characteristics and a built-in FM antenna are "first" for this price range. All of these features combine to make the 300 the biggest value today in quality audio equipment.
