has

been

degraded

by

noise

or

poor

signal

conditions,

and

you

wish

In

this

position

you

can

listen

to

stereophonic

monophonically

while

monophonic

broadcasts

appear

unchanged.

DISCRETE

FM/AUX

In

this

position,

the

addition

of

an

accessory

4

-CH

decoder

will

permit

the

reception

of

discrete

FM.

This

position,

when

not

being

used

for

discrete

FM,

may

be

used

as

an

additional

4-CH/AUX

position.

As

soon

as

an

FM

broadcast

system

has

been

selected,

Harman/Kardon

will

be

in

the

position

of

supplying

an

appropriate

decoder.

the

four

discrete

phono/aux

receptacles

on

the

rear

panel

for

playback

through

your

system

(tape

recorder,

cartridge

player,

discrete

phono

system)

with

appropriate

decoder.

This

quadriphonic

system

is

different

than

the

SQ

matrix

design

and

re-

quires

a

special

decoder

between

your

phonograph

and

Harman/Kardon

receiver.

Your

phonograph

should

employ

a

high

compliance,

low

phono

cartridge

capable

of

extending

in

frequency

response

to

beyond

45,000

Hertz

to

play

back

the

CD

-4

disc.

The

special

decoder

should

be

connected

to

the

LEFT

and

RIGHT

FRONT/BACK

DISCRETE

PHONO/AUX

receptacles

located

on

the

rear

panel

of

the

75+.

(Refer

to

"Connecting

a

Stereo

Harman/Kardon

intends

to

manufacture

a

decoder

for

use

with

the

RCA

discrete

system.

For

additional

information

on

this

system

and

the

BASS

&

TREBLE

CONTROLS

These

controls

are

employed

to

set

the

tonal

balance

of

your

stereo

or

quad

system.

The

Bass

control

adjusts

the

low

frequencies,

either

strengthening

or

diminishing

the

intensity

of

these

sounds.

The

Treble

control

adjusts

the

higher

frequencies

in

the

same

manner

—

either

strengthening

or

diminishing

the

sound.

In

most

instances

these

controls

will

be

set

to

the

"flat"

or

center

position.

If

bass

or

treble

adjustment

is

necessary,

do

not

rotate

these

controls

to

their

7

maximum

settings.

This

may

introduce

distortion

especially

if

your

speakers

cannot

handle

the

power

of

the

boosted

sound.

These

controls

should

be

used

sparingly

and

with

the

knowledge

that

live

music

is

neither

excessively

sharp

or

boomy.

You

may

adjust

both

the

BASS

and

TREBLE

for

front

and

back

pairs

of

speakers

simultaneously

or

individually.

The

inner

knobs

adjust

the

front

speakers

and

the

outer

knobs,

the

back

speakers.

In

order

to

adjust

both

pairs,

turn

either

inner

or

outer

knob.

In

order

to

adjust

front

or

back

only,

hold

one

knob

while

adjusting

the

other.

MODE

SWITCH

This

switch

allows

you

to

select

the

proper

mode

of

operation

for

the

various

sources

available.

MONO

In

this

position,

all

program

sources

will

be

reproduced

in

the

monophonic

mode.

If

an

external

monophonic

source

(one

channel)

is

used

it

MUST

be

con-

nected

to

the

appropriate

LEFT

FRONT

input

receptacles

in

order

to

reproduce

sound

in

all

speakers.

The

0

mode

indicator

light

will

be

illuminated

indicating

a

monophonic

mode

of

operation.

STEREO

In

this

position,

all

stereophonic

program

sources

will

be

reproduced

in

the

STEREO

mode.

All

pairs

of

speakers

(one

LEFT

and

one

RIGHT)

connected

to

the

FRONT

terminals

will

reproduce

stereo

program

material.

With

the

STEREO/4-CH

REAR

PANEL

SWITCH

in

4

-CH

position,

speakers

connected

to

the

BACK

ter-

minals

will

also

reproduce

stereo

in

each

pair.

In

the

STEREO

position,

the

El

mode

indicator

light

will

be

illuminated

indicating

a

stereophonic

mode

of

operation.

SQ

MATRIX

1/2

These

positions

may

be

used

to

reproduce

all

SQ

program

material.

In

the

SQ

MATRIX

1

and

SQ

MATRIX

2

positions

the

4

ig

mode

indicator

lights

will

be

illuminated.

These

lights

denote

the

methods

used

from

the

source

material

to

the

recording,

to

reproduction.

The

SQ

MATRIX

2

position

performs

the

same

function

as

the

SQ

MATRIX

1

position

except

that

it

changes

the

relationship

of

separation

between

the

LEFT

and

RIGHT

and

FRONT

and

BACK

speakers.

When

in

this

position

the

separation

between

LEFT

and

RIGHT

will

be

partially

reduced

from

that

obtained

in

the

normal

SQ

MATRIX

I

position

and

the

separation

between

FRONT

and

BACK

will

be

slightly

increased.
