You

may

connect

the

power

cord

to

any

convenient

source

of

AC

power,

110-120

volts

50

or

60

Hz'.

However,

it

may

be

more

convenient

to

make

the

power

connection

to

one

of

the

switched

AC

outlets

at

the

rear

of

your

amplifier

or

receiver.

The

44+

power

switch

can

then

be

left

on;

power

for

it

will

be

supplied

whenever

your

amplifier

or

receiver

is

turned

on.

A

switched

AC

outlet

is

provid-

ed

at

the

rear

of

the

44+

for

your

conve-

nience.

Power

is

available

from

it

only

when

the

44

+

is

on.

(NOTE:

Automatic

record

changers

should

not

be

connected

to

the

AC

power

outlet

of

the

44

.

Their

shut-off

mechanisms

require

power

through

the

entire

shut-off

cycle

to

ensure

complete

disen-

gagement

of

the

drive

mechanism.

If

power

sup-

plied

to

a

changer

is

interrupted

before

the

drive

mechanism

has

disengaged,

rumble

and

mechanical

problems

may

result.)

CD

-4:

Other Equipment

and

Adjustments

The

CD

-4

system

relies

on

the

transmission

of

signals

at

frequencies

well

beyond

20kHz.

Cartridges

(pickups)

designed

for

stereo-

phonic

use

are

not

generally

capable

of

han-

dling

these

frequencies

at

the

levels

required

for

the

best

reproduction

of

CD

-4

discs.

Spe-

cial

CD

-4

cartridges

are

available

that

are

designed

to

handle

these

frequencies.

Only

the

use

of

one

of

these

cartridges

will

allow

the

best

reproduction

of

CD

-4

discs

through

your

system'.

Adjusting

the

Separation

Controls

Each

44+

is

adjusted

at

the

factory

for

optimum

separation.

The

marks

on

the

sepa-

ration

controls

indicate

the

points

that

will

be

approximately

correct

for

most

CD

-4

car-

tridges.

Cartridges

do

vary

from

manufac-

turer

to

manufacturer

so

you

may

wish

to

make

a

more

precise

adjustment

for

your

individual

requirements,

but

the

following

steps

will

not

be

necessary

in

most

cases.

Using

a

CD

-4

disci

with

separation

test

tones:

1.

Set

the

FUNCTION

switch

on

the

front

panel

of

the

44

+

to

the

"CD-4/AUTO"

position.

(The

"mode"

switch

of

your

ampli-

fier

or

receiver

must

be

in

discrete

4

-channel

position.)

2.

Play

the

test

tone

for

each

channel

(left

and

right)

and

adjust

the

corresponding

SEPARATION

control

for

minimum

output

from

the

corresponding

back

channel.

Set-

ting

the

balance

control

of

your

amplifier

or

receiver

so

you

can

hear

only

the

back

chan-

nel

you

are

adjusting

will

aid

you

in

finding

the

"null"

(minimum

output)

point.

When

both

left

and

right

channels

have

been

nulled,

the

44+

and

your

system

are

adjust-

ed

for

optimum

CD

-4

separation.

Operating

the

44+

On

the

44

+

front

panel,

along

with

the

power

switch

and

its

associated

LED

indicator

lamp,

there

is

a

three

-position

FUNCTION

switch

marked

STEREO/MATRIX,

CD

-4

AUTO,

and

BYPASS;

and

an

LED

indicator

lamp

marked

CD

-4

AUTO.

1.

CD

-4

AUTO

can

be

used

to

play

all

the

discs

in

your

collection.

When

CD

-4

discs

are

played,

the

carrier

present

in

the

grooves

of

the

disc

will

be

sensed

by

the

44+

and

activate

the

demodulation

circuitry.

Four

discrete

channels

of

information

will

emerge

at

the

front

and

back

outputs

and

travel

into

your

amplifier

or

receiver.

This

action

will

be

indicated

by

the

CD

-4

AUTO

lamp.

The

"mode"

switch

on

your

amplifier

or

receiver

must

be

in

the

discrete

position

so

the

four

channels

pass

through

with

full

separation.

When

matrix

(SQ,

etc.)

or

stereo

discs

are

played,

the

44

+

will

pass

their

signals

through

in

their

original

two

-channel

1.

Consult

Harman/Kardon

for

information

about

use

with

other

power

sources.

2.

The

connection

between

the

CD

-4

cartridge

and

the

44-I-

most

exhibit

a

total

capacitance

of

less

than

WOO'

(picofarads)

to

assure

proper

CD

-4

operation.

If

triggering

of

the

CD

-4

circuitry

and

LED

indicator

does

not

occur

while

playing

a

CD

-4

disc,

consult

your

dealer,

or

the

turntable

manufacturer,

for

information

on

the

availability

of

connecting

cables

of

low

capacitance.

3.

A

special

II

armaniKardon

disc

is

available

from

your

dealer

at

a

nominal

charge.
