Surround

Sound

The

AVR20

is

equipped

with

3

types

of

surround

processors

(Dolby

Pro

Logic,

Dolby

3

Stereo

and

HALL)

which

provide

a

sense

of

presence

and

expansion

and

let

you

enjoy

surround

-

sound

in

your

home.

Every

day,

we

are

exposed

to

sounds

coming

from

our

surroundings.

Some

sounds

reach

our

ears

directly

from

the

source,

some

indirectly

reflected

by

walls

or

ceilings.

Sounds

of

voices

reach

us

from

behind,

sounds

of

cars

reach

us

from

the

side.

Sounds

coming

from

all

around

us

are

called

"surround

-sounds".

In

order

to

recreate

with

as

much

precision

as

possible

that

special

sound

in

movie

theaters,

speakers

are

placed

both

in

front

of

and

behind

the

listeners.

One

reason

that

sound

from

the

television

in

our

homes

is

so

different

from sound

in

movie

theaters

is

because

usually

sound

from

a

television

only

comes

from

in

front

of

the

viewer.

With

a

surround

system,

the

sounds

of

applause

and

cheers

from

the

stands

during

a

baseball

game

on

TV

come

from

in

front

and

in

back,

from

the

left

and

right.

The

sound

from

a

TV

equipped

with

a

single

speaker

(or

2

speakers

with

stereo

televisions)

sounds

very

different

from

the

actual,

"live"

sound.

HALL

Hall

mode

works

best

for

recorded

concerts

and

other

music

programs.

In

this

mode,

the

front

speakers

provide

a

normal

stereo

effect

while

the

rear

speakers

provide

a

reverberated

sound.

This

reverberation

helps

simulate

the

sound

you

might

hear

at

a

live

concert.

Combining

the

front

and

rear

signals

so

that

you

can

enjoy

a

regenerated

sound

field

which

has

comparatively

more

presence

and

a

more

expansive

feeling

from

than

that

of

ordinary

SURROUND

A

great

number

of

movies

made

in

recent

times

have

the

sound

track

specially

encoded

with

the

Dolby

Surround

mode

(carrying

the

(Dolby

Stereo)

or

(Dolby

Surround)

trademark*).

The

front

speakers

provide

the

dialogue

and

the

normal

stereo

effect,

while

the

rear

speakers

reproduce

the

surround

signals.

This

position

provides

excellent

results

when

watching

television

programs,

video

software,

video

discs

or

video

tapes

of

stereo

television

broadcasts

encoded

with

Dolby

Surround.

Dolby

Stereo

films

have

dramatically

changed

the

role

of

the

movie-goer

from

that

of

observer

to

that

of

participant.

Clearer

dialogue,

richer

music,

enveloping

ambience,

on

-screen,

and

making

high-fidelity

multi

-dimensional

sound

are

essential

parts

of

cinematic

presentations.

Imagine

recreating

the

same

sort

of

audio-visual

experience

right

in

your

own

home.
