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.

SAE TWO C3D

 The cassette deck with a mind of its own - SAE TWO C3D
What's gotten into the C3D? A microcomputer chip. A chip that will prevent you from accidentally misusing the controls, and from stretching or tearing tape. A chip with a memory for finding a predesignated spot on a cassette. It's full, solenoid-operated logic control. There's more ; Dolby noise reduction, switches for maximum utilization of latest tape formulations, and optional accessory remote control.
The C3D. What a mind.
