the Product
1|vER 20 yEARS AGo, Avery Fisher introduced America's first high fidelity radio- \-/ phonograph. That instrument attained instant recognition as heralding a new era in the enjoyment of reproduced music. A number of the features of that early high fidelity radio-phonograph were so basic that they are used to this day in all high fidelity equipment. The engineering achievements of Avery Fisher and the world-wide reputation of his products have been the subject of articles in Fortune, Tin're, pageant,
The New York Times, coronet, Lile, High Fidetity, Esquire, and other publications.
Benefit concerts for the National Symphony orchestra in washington and the phila-
delphia orchestra, demonstrating the great advances in reproducing equipment, used FISHER instruments to play back the recordings that had just been made in the presence of. the audience. "Fascinating evening, acoustically and musically," was the Philadelphia Inquirer's comment, "the reproduction had remarkable fldelity." Trve magazine stated, "Listeners could hardly tell the difference between real and electronic."
The FISHER instrument you have just purchased has been designed to give you many years of pride and enjoyment. It is the product of a company dedicated to bringing reproduced music in its finest form, to the homes of America.

STEREOPHONIC SOUND
In monaural high fidelity systems, tbe reproduced sound has all the characteristics of
the original performances - with two exceptions. These are d,irection and, d,isnnce. With
the advent of stereophonic high fidelity systems, all the charaeteristics of live sound are
now capable of being reproduced in the home or auditotium. THE FISHER 5I4 in
conjunction with the Stereo Cornpanion, constitutes a complete stereophonic system.
Reproduetion of the live sound characteristics of direction and distance are made pos-
eible by the use of trto sound sources and. two sound channels. For example, two micro-
phones are placed before an orchestra so that they "hear" the music as we would, with
both ears. What is picked up by each microphone is then recorded separately and in-
dependently on reeord or tape, or broadcast as a stereo radio program. The stereo pro'
gram is then reproduced through two separate sound channels. The sound originally
picked up by the microphone on the left is used to drive a speaker system on your left,
while the souud picked up by the microphone on the right simultaneously drives a
speaker system placed on your right.
The efiectiveness of high fidelity stereophonic sound in achieving realism is much
greater than might be imagined on the basis of the simple explanation just given. The
stereo system actually spreads out the orchestral sound in the same manner as it would
emanate from a stage. In other words, instruments located at center stage are heard at a
point mid'way between the speakers. The other orchestral instruments can be located
accordingly from left to right. This results in a realism and clarity never belore possible
in high fidelity systems.
The {ollowing stereophonic program sources are already in use, or will be available
in the very near future: FM-AM' FM'FM, and FM Multiplex radio broadcasts; com-
mercial and home tape recordings; commercial disc recordings. THE FISHER is
equipped to handle all these sources, in addition to all standard monaural programs.
