EQUALIZER

CONTROLS

These

are

equalizer

controls

for

the

bands

60

Hz,

150

Hz,

400

Hz,

1

kHz,

2.4

kHz,

6

kHz

and

15

kHz.

When

the

equalizer

switch

has

been

set

to

ON,

these

con-

trols

may

be

adjusted.

When

a

control

is

raised

upwards

from

the

‘‘0”’

position,

the

frequency

band

corresponding

to

that

control

will

be

emphasized;

when

the

control

is

lowered,

the

frequency

band

will

be

attenuated.

These

controls

can

be

used

independently

for

right

and

left

chan-

nels.

NOTE:

/n

order

to

protect

your

speakers

from

damage

resulting

from

excessively

large

inputs,

whenever

augmenting

high-frequency

sounds

over

a

wide

range,

be

sure

not

to

raise

your

amplifier’s

sound

volume

too

high.

USING

THE

EQUALIZER

CONTROLS

The

graphic

equalizer

divides

the

music

source

into

a

number

of

frequency

bands

and

boosts

or

attenuates

the

level

at

each

of

the

frequencies,

enabling

much

finer

sound

quality

adjustments

than

ordinary

tone

controls

and

sound

field

compensation.

Some

examples

of

operation

are

given

below.

COMPENSATING

FOR

THE

PLAYBACK

FREQUENCY

RESPONSE

The

frequency

response

of

a

phono-cartridge

or

speaker

has

peaks

and

dips

in

the

high

range

and

low

range.

It

can

be

made

flat

by

adjusting

finely

the

controls

on

the

graphic

equalizer.

IMPROVING

THE

ACOUSTICS

OF

THE

LISTENING

ROOM

The

ideal

listening

room

is

one

where

the

transmission

fre-

quency

response

is

flat.

In

actual

fact,

however,

the

acoustics

vary

depending

on

the

effects

of

the

structure

of

the

room

and

its

furniture,

and

on

the

listening

position.

Although

there

is

minimal

treble

attenua-

tion

in

a

listening

room

surrounded

by

hard

walls

and

windows

and

having

a

bare

floor,

the

bass

sounds

are

reflected

to

a

great

extent.

In

rooms

like

this,

turn

up

the

150

Hz

control

slightly.

.

In

a

room

surrounded

by

drapes

and

with

carpets

on

the

floor,

there

is

minimal

reflection

of

the

sound

and

both

the

bass

and

the

treble

are

absorbed.

In

slightly

and

turn

up

the

frequency

controls

above

2.4

gradually.

The

above

examples

are

extremely

general.

The

acoustics

undergo

change

in

accord-

ance

with

the

furniture

in

the

listening

room,

the

height

of

the

ceiling

and

the

listening

position,

among

other

factors.

Play

music

and

try

operating

each

of

the

controls

to

produce

the

best

effect.

USING

THE

EQUALIZER

CONTROLS

COLORING

THE

REPRODUCED

SOUND

All

instruments

and

vocals

have

their

own

frequency

band,

as

shown

in

the

figure.

By

moving

the

controls

up

or

down,

the

volume

of

the

in-

struments

preferred

can

be

boosted

or

other

instruments

can

be

attenuated.

For

instance,

it

is

possible

to

boost

the

60

Hz

frequency

and

give

the

bass

drum

a

greater

‘‘punch’”’

or

boost

the

1

kHz

frequency

and

position

the

vocals

at

the

front.

When

the

6

kHz

frequency

is

boosted,

the

cymbals

and

‘high

hat’’

sound

much

clearer.

Instruments

and

vocals

have

a

great

many

harmonic

com-

ponents

along

with

the

fundamental

frequency

band

and

so

you

can

have

lots

of

fun

operating

the

7

controls

to

achieve

the

sound

of

your

choice.

NOTE:

In

order

to

protect

the

speakers

from

damage

resulting

from

power

overload,

do

not

excessively

increase

the

stereo

amp-

lifier’s

volume

level

when

boosting

the

treble

range

on

this

unit.

Coloring

sound

of

vocals

or

instruments

The

sound

of

vocals

and

instruments

can

be

by

operating

the

controls.

For

instance,

when

the

400,

1

2.4

are

raised

and

the

other

lowered,

people’s

sound

as

Any

prevented

by

lower-
