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.

Superscope CD-302A cassette deck

Stereo cassette tape deck, features:

Built-in Dolby Noise Reduction System - with internal/external switching that enables it to operate as an independent out board playback Dolby system. Unlike most other Dolbyized units, the CD-302A Deck can also deprocess Dolbyized material from FM broadcasts and other tape recorders.

Automatic Shut-Off - that disengages the cassette drive mechanism at end-of-tape in record and play modes.

 

 

Recording Peak Limiter - that monitors and holds the recording level below saturation to prevent distortion while maintaining a full dynamic range.

Tape Select Switch - for proper bias and equalization when using either standard or chromium dioxide tape.

Mechanical Locking Pause Control - that enables you to pause during playback or recording without disengaging controls

VU Meters, Function Indicators and Cassette Compartment - that are illuminated for easy viewing

3-Digit tape Counter - with a reset button.

Walnut-Grained cabinetry - and the professional styling you'd expect to find only in more expensive units.
