PRACTICAL

APPLICATIONS

OF

THE

PARAMETRIC

EQUALIZER

The

C-80's

Parametric

Equalizer

offers

extensive

control

over

tone

quality.

It

can

be

used

to

adjust

for

room

acoustics,

speaker

placement,

or

personal

preferences.

A

LOW

band

and

a

HIGH

band

are

provided,

each

with

its

own

adjustable

center

frequency,

bandwidth,

and

level

(boost/cut).

For

For

instance,

if

Tailoring

the

Sound

n

The

Parametric

Equalizer

can

also

be

used

to

"shape"

the

sound

i

ta

emphasize

vocais,

balance

the

tonal

effect

between

varying

instruments,

or

create

any

type

of

sound

you

like.

Emphasizing

the

vocals,

or

mid-range

presence,

for

example,

can

be

done

by

setting

the

center

FREQUENCY

to

between

1

kHz

and

3

kHz,

setting

the

BANDWIDTH

controi

to

the

maximum

WIDE

position,

and

then

boosting

the

LEVEL

slightly.

Conversely,

vocals

or

midrange

presence

can

be

slightly

attenuated

by

cutting

the

LEVEL

slightly,

thereby

blending

vocals

into

the

background,

facilitating

conversation

over

the

music

or

enhancing
