PROCEDURE

(Cont.)

6.

AM.

Thi8

position

selects

the

AM

section

of

your

receiver

for

AM

reception.

STEREO

HEADPHONE

RECEPTACLE:

The

stereo

headphone

receptacle,

located

on

the

front

panel,

will

accept

any

headphone

with

any

impedance

rating.

The

headphone

receptacle

is

"on"

at

all

times.

If

you

wish

to

listen

to

the

headphones

alone,

see

the

paragraph

on

"Speaker

Switch".

CONTOUR

SWITCH:

One

of

the

limitations

of

human

hearing

is

its

tenden-

cy

to

lose

sensitivity

to

the

very

low-pitched

sounds

as

the

sound

level

of

a

progr'am

is

reduced.

It

is

this

characteristic

(known

as

the

Flet-

cher

-Munson

effect)

which

causes

one

to

play

music

programs

at

high

listening

levels

in

order

to

experience

the

full,

rich

tone

available

from

fine

modern

recordings.

The

HARMAN-KARDON

CONTOUR

switch

compensates

for

this

effect,

thereby

eliminating

high

listening

levels

as

a

requisite

for

full

enjoyment

of

reproduced

music.

For

warm,

full-bodied

reproduction

at

low

listening

levels,

throw

the

CONTOUR

switch

"IN".

At

high

levels,

the

contour

switch

has

no

effect.

SPEAKER

SWITCH:

The

speaker

switch

is

used

to

defeat

the

speakers

while

listening

to

the

stereo

headphones.

To

defeat

the

speakers,

throw

the

switch

to

the

"off"

position

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

automatically

switch

in

the

multiplex

section,

and

you

will

re-

ceive

the

broadcast

in

full

stereo

through

your

speakers.

Should

the

station

conclude

broadcasting

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

broadcast,

the

STEREOMATIC

circuit

automatically

switches

your

receiv-

er

to

the

stereophonic

mode

of

operation

and

back

again

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,

want

to

listen

to

this

stereo

broadcast

monophonically,

simply

place

the

function

selector

switch

to

the

FM

MONO

position.
