(such as the FISHER

X-100 will perform as a stereophonic sound system of the highest quality.

NOTE

ON

STEREOPHONIC SOUND

[lnn

onveropurur of stereophonic sound has brought us close to

I

achieving "Concert

Hall" realism in the home.

This dual"channel system ofiers a distinct advantage over monophonic

(single-channel) systems sions by virtue of two important audio characteristics: the dimenof d.irection and depth. These live sound qualities are for the most part missing in monophonic systems because recordings are made and reproduced over a single channel.

This listening is somewhat analogous to to music with one ear. Stereophonic recording techniques, however, utilize two separate banks of microphones which are positioned at the le{t and right sections of the orchestra. ment, the microphones receive the musical sounds

In this arrange-

in

much the same manner as the two ears of a listener. The sound picked up by each

Where possible, speakers should be placed against separated by a flat wall and a minirnum oI five feet. As a rule of thumb, the best listening area

will

be at a distance about l1/z times as great as the separation between feet apart, listening the speakers.

For example: will be best in an area about nine feet from, and opposite the two systems. Because

if

the speakers are six of varying acoustical conditions, however, the speakers may have to.be repositibned to achieve the best stereophonic results.

FIGURE

Reor ponel of

If

you place wall"type speaker systems in the room corners, undesir' able efiects may be introduced.

Try placing them, instead, on the same wall, a short distance from the corners.

If

you own two corner-type speaker systems, experiment by leaving one in a corner and placing the other against a flat wall. Then com' pare this arrangement with the original one.

In a long.narrow room, placing the speakers on the long wall may bring better results than placing them on the short one.

Speoker

Connections

Speaker terminal strips are provided for each channel to accommodate speakers, or speaker systems, having an approximate'impedance of

4, 8, or

16 ohms.

The connecting cable may be up to

100

Ieet in length, and ordinary lamp cord can be used. Connect one lead of the cable from the speaker on the

may be necessary to space loudspeakers farther apart to cover a wider area, a'ohole" may develop in the center'

This apparent lack of sound in the center will become more noticeable the distance between the two speakers is increased.

It

is possible to

Channel

"phantom" channel' By connecting an additional amplifier and loudspeaker to this output jack, and posi tioning the speaker between the left and right speakers, the stereo" phonic pattern o{ sound

will

be augmented.

The third amplifier need not be equipped with tone controls' since these are provided hy the

X'100,

A volume control, or input level control, will be helpful, however,

in

order that the volume of the center speaker may be adjusted to the necessary level. Connect a short length

oI

shielded cable,

of

the low-capacitance type, {rom the

CENTER

CHANNEL output jack on the rear panel o{ the X'100 to an input o{ the center channel amplifier. The length of cable from the amplifier to the center speaker can be considerably longer

(up to

100 feet, or more) depending on the type of amplifier used.

The center speaker can also be used in an adjoining room or some other remote location. Although the output from this extension speaker will be monophonic,

it

will contain the composite stereo signal.

Behind

the Product

AVERY FISIIEB f oundet and, President;

Fisher Radio Cotpordtion

-flwENTy-FouR

YEARs AGo,

Avery Fisher introduced

America's

first

high

I fidelity radio-phonograph.

That

instrument attained instant recognition,

for it

opened a new era in the faithful reproduction of records and broadcasts. Some of its features were so basic that they are used in all high fidelity equipment to this day.

One of these models is now in the permanent collection of the Smithsonian Institution as an example of the earliest high fidelity instruments commercially available in this country.

The engineering achievements of Avery

Fisher and the world-wide reputation of his products have been the subject of descriptive and biographical articles in Fortune, Time,

Pageant, The

New York

Times,

Lif e,

Coronet, High Fidelity, Esquire, The

Atlantic, and other publications. Benefit concerts for the National Symphony Orchestra in

Washington and the Philadelphia Orchestra, demonstrating recording techniques, and the great advances in the art of music reproduction, used

FISHER high fidelity instruments both for recording and playback, to the enthralled audiences.

FISHER equipment formed the key part of the high fidelity demonstration at the American National Exposition in

Moscow,

July

1959.

FISHER broadcast stations

FM

and

FM-AM tuners are the most widely used by

for

monitoring and relay work, and by research organizationsunder conditions where absolute reliability and maximum sensitivity are a'must.'

The FISHER instrument you have just purchased was designed to give you many years of pride and enjoyment.

If

you should desire information or assistance on the installation or performance of your FISHER, please write directly to Avery Fisher,

President,

Fisher Radio Corporation, Long Island City.
