SELECTING

MONOPHONIC

OR

FM

STEREO

BROADCASTS

Under

normal

use

the

Function

Selector

Switch

should

be

placed

in

the

FM

STEREOMATIC

position.

If

the

receiver

is

tuned

to

a

monophonic

FM

broadcast,

the

special

STEREOMATIC

circuit

automatically

defeats

the

multiplex

circuitry

and

the

receiver

will

reproduce

monophonic

sound

through

both

speakers.

Should

this

station

begin

to

transmit

stereo,

the

STEREOMATIC

circuit

will

auto-

matically

switch

in

the

multiplex

section

and

you

will

receive

the

broadcast

in

full

stereo

through

your

speakers.

Should

the

station

conclude

broad-

casting

in

stereo,

your

receiver

will

automatically

switch

back

to

monophonic

reception.

The

exclusive

Harman-Kardon

STEREOMATIC

circuit

is

always

operative

—even

as

you

tune

across

the

FM

dial.

As

you

tune

to

a

stereophonic

broad-

cast the

STEREOMATIC

circuit

automatically

switches,

your

receiver

to

the

stereophonic

mode

of

operation

—and

back

to

monophonic

as

the

stereo

station

is

passed.

Should

you

receive

a

weak

stereo

signal

whose

quality

has

been

degraded

by

noise

or

excessive

multipath,

and

you

wish

to

listen

to

this

stereo

broadcast,

monophonically,

place

the

function

selector

switch

in

the

FM

MONO

position.

STEREO

INDICATOR

LIGHT

A

Stereo

indicator

light

is

located

directly

behind

the

FM

dial

glass

and

operates

in

conjunction

with

the

FM

STEREOMATIC

position

of

the

Function

switch.

The

light

visually

indicates

the

reproduc-

tion

of

stereo

through

your

receiver.

To

tune

for

FM

stereo

proceed

as

follows:

1.

Place

the

function

selector

switch

in

the

FM

STEREOMATIC

position.

2.

Tune

carefully

to

the

desired

station,

using

your

tuning

meter

for

maximum

deflection.

Your

light

will

now

glow

if

you

are

tuned

to

a

DIAL

SCALE

The

Dial

Scale

on

the

SC3

receiver

is

marked

with

two

scales,

an

FM

frequency

scale

(88-108

MC),

and

a

logging

scale

(0-100).

Since

most

FM

stations

operate

on

frequencies

which

are

not

whole

numbers

(such

as

96

MC

as

compared

to

96.3)

ideally

each

megacycle

division

on

the

frequency

scale

should

be

divided

into

10

parts

to

enable

the

user

to

pinpoint

the

location

of

the

station.

This

would

require

a

dial

scale

which

would

be

longer

than

the

front

panel.

The

logging

scale

which

is

divided

into

100

equal

parts

provides

a

means

of

fi

nding

your

favorite

station,

once

you

have

noted

its

position

on

the

logging

scale.

For

example,

in

New

York

City,

WQXR

operates

on

96.3MC.

After

locating

this

station

through

the

use

of

the

frequency

scale

(between

96

and

98

MC),

you

fi

nd

that

the

pointer

falls

on

46

on

the

logging

scale.

Make

a

note

of

this

setting

and

when

you

next

want

to

tune

to

WQXR,

all

that

is

necessary

is

to

set

the

pointer

to

46

on

the

logging

scale.

EQUALIZATION

In

order

to

achieve

good

reproduction

of

the

wide

range

of

frequencies

in

music

and

to

make

neces-

sary

adjustments

for

the

limitations

of

the

recording

technique,

record

manufacturers

have

found

it

necessary

to

modify

the

actual

frequency

response

of

the

music

while

it

is

being

recorded.

Thus,

to

avoid

overcutting

and

consequent

distortion,

a

measured

and

deliberate

reduction

is

effected

in

low

frequency

response

by

selecting

a

"turnover

frequency"

and

by

recording

attenuated

response

below

that

point.

To

assure

optimum

signal

to

noise

at

the

high

frequency

end

when

the

record

is

played

at

home,

the

highs

are

deliberately

exaggerated

during

the

recording

process.

A

measured

and

de-

liberate

boost

is

effected

above

a

certain

frequency.

This

combination

of

deliberate

exaggeration

at

the

low

and

high

ends

of

the

frequency

response

can

be

expressed

in

a

recording

curve.

When

the

record

is

played

a

mirror

image

of

that

curve

should

be

available

so

that

the

ideal

"flat"

response

may

be

achieved.

The

PHONO

positions

of

the

Function

Selector

automatically

select

the

proper

equalization

that

is

required.

FUSES

Your

receiver

is

protected

by

a

2

1

/

2

amp-3AG

fuse.

In

the

event

of

fuse

failure

replace

ONLY

with

the

same

type

used.

Replacing

with

a

fuse

of

a

higher

rating

will

not

protect

the

instrument

and

may

result

in

severe

damage.
