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.

 AM/FM Multiplex Stereo Tuner Amplifier Solid State
This attractive solid state introduces a whole new performance standard for receivers in the medium power range.  With a new FET frontend for increased FM sensitivity, input terminals for both 75 and 300 ohms antennas, and an FM channel separation figure of better than 35 dB, it is perhaps the finest performing FM receiver ever made under 100 watts.
Its audio characteristics are also superb  a power bandwidth from 20 to 40,000 Hz, distortion factor of less than 1% at rated output and damping factor of 60 at 8 ohms.
 Other features include short-free output terminals for two complete speaker systems, a new type of noise canceler, automatic FM mono/stereo switching with indication and the latest black window design.
