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 Speaker System

 Illustrated is an articulateddual coaxial speaker systemshown in cutaway form to reveal its unusual design. It is the standard equipment on every Fisher instrument and combines a 15'' bass speaker with a horn-type high frequency speaker, both equipped with Alnico-5 magnetsThis system features smooth response, minimum distortion and exceptional polar distribution and presence. A dividing network is provided to channel the upper treble and overtones to the high frequency unit and middle and low tones to the massive bass speaker. A multicellular horn system is available optionally at additional cost.

Illustrated is the greatest development of the last ten years in fine  sound reproduction for the home. It is a multicellular-horn coaxial speaker utilizing two driving units. The larger is designed to handle with exceptional efficiency the first 5-1/2 octaves of he scale. The second unit, small in sizeis built with the microscopic accuracy of a fine watchThis mechanism converts to acoustic energy the rapid and delicate pulses of the higher tones and overtones. A nest of eightexponential horns diffuses the ordinarily bullet-like  higher tones over an angle of eighty degreesThis speaker system is optional equipment on the Fisher.
