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.

The Fisher TA-600 (1960)

The Fisher Model 600 is a complete stereophonic FM-AM tuner, stereo audio control and dual-channel power amplifier - all in one integrated chassis. Only the speaker need be added to permit the 600 to function as a high-fidelity sound system for the reception of standard FM or AM programs or for FM-AM stereo broadcasts.
In addition to playing Fm and AM radio programs, the Model 600 can be used as the stereo control center and stereo amplifier for the reproduction of phonograph records and tapes. Any type of record changer or player, tape deck or tape recorder may be operated with the Model 600 receiver, either monophonically or stereophonically . Provision is also made for plugging a multiplex adaptor into the Model 600 for receiving FM multiplex stereo broadcasts.
