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 200

 AM/FM Multiplex Stereo Tuner Amplifier
This attractive solid state compact was created especially for the person who has never owned a quality stereo system before. Attach a small set of speaker systems to it and you're ready for rich FM stsreo reception, plus regular FM and AM programs like you've never heard them before. The 200, despite its compact size and moderate price, incorporates all on Sansui's sophisticated audio know-how, such as an FET frontend for unparalleled FM sensitivity and selectivity, and automatic FM stereo/mono switching. At your convenience, you can start to add other components. A quality stereo turntable, stereo tape deck or recorder, stereo headphones and other components. You can built the 200 into a complete audio system. At 17 watts the Sansui 200 has enough power to fill the average home without straining. Weighing only 13,2 lbs., it is lighter than many conventional radios capable of receiving AM broadcasts only. If you've thought you could never afford to move up into the world of professional stereo before, we invite you to investigate the Sansui 200 more throughly. We think it could change your mind completely.
