1)

Plug

one

end

of

the

speaker

cable

into

the

re-

ceptacle

on

the

rear

of

your

left

speaker

(this

is

the

speaker

on

the

left

as

you

face

the

speakers).

2)

Plug

the

other

end

of

the

speaker

cable

into

the

LEFT

speaker

receptacle

on

the

rear

of

the

receiver.

3)

Similarly

connect

the

other

speaker

cable

to

your

right

speaker.

4)

Attach

the

end

of

the

speaker

cable

to

the

5)

Your

receiver

is

now

connected

for

stereo

operation.

CONNECTING

THE

FM

ANTENNA

Due

to

the

exceptionally

high

sensitivity

of

your

receiver

the

48"

wire

supplied

is

sufficient

for

all

but

the

most

difficult

locations.

The

balanced

antenna

input

is

designed

to

accept

a

300

ohm

antenna,

indoor

or

outdoor

type.

When

using

the

antenna

supplied

connect

one

end

of

the

48"

wire

to

either

FM

antenna

terminal.

Horizontal

placement

of

the

antenna

offers

maxi-

mum

polarization

for

optimum

reception.

The

antenna

may

be

tacked

to

the

back

of

the

mold-

ing

behind

the

equipment

or

to

the

shelf

you

use.

In

more

remote

locations,

an

outside

Yagi,

folded

di

-pole

or

omni-directional

antenna

is

re-

commended

(Jerrold/Taco

FMP

For

the

greatest

gain,

an

8

to

14

element

Yagi

designed

for

the

FM

band

is

suggested.

A

Yagi

however,

is

very

directional

and

it

may

be

desirable

to

use

an

antenna

rotor

if

a

full

360°

coverage

is

required.

For

reception

in

the

suburbs,

an

outside

folded

di

-pole

or

omni-directional

di

-pole

is

re-

commended.

CONNECTING

A

STEREO

TAPE

RECORDER

Since

most

stereo

tape

recorders

include

their

own

record

and

playback

pre

-amplifiers,

it

is

not

desirable

to

connect

the

output

of

the

recorder

into

any

low

level

input

receptacles.

This

will

result

in

overloading

of

the

low

level

stage

and

cause

distortion.

Connect

two

to

the

LEFT

and

the

rear

panel

of

a

recording,

connect

the

inputs

of

your

recorder

to

the

LEFT

and

RIGHT

TAPE

OUT

re-

ceptacles.

This

will

enable

you

to

make

a

stereo-

phonic

recording

with

the

proper

recording

equali-

zation

as

determined

by

your

recorder,

while

simul-

taneously

listening

to

the

program

material

through

your

speaker

system.

The

recording

signals

from

the

TAPE

OUT

receptacles

are

unaffected

by

the

tone

controls

or

volume

setting

of

the

receiver

to

insure

an

absolutely

fl

at

response.

CONNECTING

A

MONOPHONIC

TAPE

RECORDER

If

a

monophonic

tape

recorder

is

to

be

used

with

your

receiver

connect

the

recorder

output

to

either

the

LEFT

Or

RIGHT

TAPE

AMP/AUX

input

re-

ceptacle

located

on

the

rear

panel.

This

will

enable

you

to

play

back

your

monophonic

tapes.

If

your

recorder

is

stereo

playback

but

records

monophonically,

connect

the

output

as described

in

the

previous

section

on

connecting

a

stereo

tape

recorder.

Connect

the

input

for

recording

mono-

phonically

as

described

below.

Connect

the

input

of

your

recorder

to

either

the

LEFT

or

RIGHT

TAPE

OUT

receptacle.

This

will

enable

you

to

record

monophonically

while

simul-

taneously

listening

to

the

program

through

the

re-

ceiver

and

speakers.

Operation

IP

rocedure

Every

control

on

this

receiver

serves

a

specific

useful

function

and

is

important

for

the

proper

operation

of

your

stereo

system.

It

is

important

to

note

that

under

no

circumstances

should

this

receiver

be

operated

without

either

a

speaker

or

resistive

load

(4

115

W)

across

both

the

output

terminals.

ON/OFF

SWITCH

The

power

switch

is

located

on

the

volume

con-

trol.

In

the

full

counter

-clockwise

position

the

re-

ceiver

is

off.

Rotate

the

control

clockwise

to

turn

the

receiver

on.

TUNING

CONTROL

The

TUNING

CONTROL

is

located

directly

to

the

right

of

the

dial

glass

and

is

used

to

select

the

desired

station.

VOLUME

CONTROL

The

VOLUME

CONTROL

on

your

receiver

is

essentially

two

controls

in

one,

mechanically

tied

together,

to

be

operated

by

one

knob.

The

volume

control

varies

both

channels

simultaneously

and

is

used

to

adjust

the

volume

level

of

program

material

fed

into

the

stereo

system.

Its

effect

can

be

modified

by

the

special

Harman-Kardon

CONTOUR

switch.

BALANCE

CONTROL

The

nature

of

stereophonic

reproduction

is

such

that

it

requires

two

identical

channels

to

attain

the

highest

degree

of

faithfulness

and

spatial

distribu-

tion.

Any

variation

in

the

efficiency

of

one

channel

as

compared

to

the

other

will

disturb

this

relation-

ship.

As

there

may

be

slight

differences

between

the

location

of

the

two

speakers,

tape

heads,

cart-

ridge

coils,

etc.,

your

receiver

includes

a

special

control

to

balance

one

channel

against

the

other.

Sufficient

range

is

covered

by

this

control

to

permit

rebalancing

of

the

overall

system

even

in

extreme

cases

where

unbalance

exists.

It

should

be

noted

that

the

BALANCE

control

may

be

set

anywhere

within

its

range

of

adjustment

to

attain

system

balance.
