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.

Invert-O-Matic

Akai engineers have investigated and developed ways of perfecting all of the weak points in cassette recording and playback. These improvements made from every angle have been concentrated in the most "up-to-date design" to bring you the World's First top rate performance Akai Cassette Invert-O-Matic Tape Deck

The Invert-O-Matic is an epoch-making automatic reversing system. By the mere pressing of a button, the cassette will reverse itself automatically inside the tape deck. This system will not only do away with the trouble of setting the cassette by hand in future, but the new tape movement mechanism is simplified and because of the stability mechanism and high performance, this new device produces amazingly true hi-fi sound.

By depressing the Auto Button during playback, continuous revers is actuated (at the end of the tape, the cassette will automatically invert and playback will continue for as long as is desired). When the Manual Revers Button is depressed, instant manual reverse is effected.

Akai is the World's First to succeed in developing automatic and manual reverse applicable during recording. With this new mechanism, a C--120 cassette tape will accommodate two hours of uninterrupted recording.

 

A Wonderful Combination

The CS-50D employs the very simplest and easiest loading method. Just insert cassette into slot provided. For removal of cassette, simply press the Cassette Eject Button

The CS-50D employs a 4-Track Stereo recording and Playback System.

For playback, and external power amplifier and a pair of hi-fi speakers are required Akai Models AA-6300 amplifier and SW-125 speakers, are highly recommended.
