system

you

will

use

two

pairs

of

speakers:

the

FRONT

SPEAKERS,

the

and

the

SPEAKER.

|

You

will

probably

use

your

present

stereo

speaker

system

for

the

FRONT

SPEAKER

pair.

The

rear

and

center

speakers

do

not

need

to

be

of

such

high

quality.

But

they

should

have

high

enough

power

handling

to

accept

the

maximum

output

of

this

unit

that

will

drive

them.

FRONT

SPEAKERS

Place

the

FRONT

SPEAKERS

in

the

normal

position.

REAR

SPEAKERS

Place

the

REAR

SPEAKERS

beside

your

listening

position

and

facing

a

little

inward.

They

should

be

nearly

six

feet

up

from

the

floor.

CENTER

SPEAKER

Place

the

CENTER

SPEAKER

precisely

between

the

two

FRONT

SPEAKERS.

(To

avoid

interference,

use

a

magnetically

shielded

speaker.

If,

however,

it

is

not

effective,

keep

the

speaker

away

from

TV

sets.)

SURROUND

This

unit

employs

the

Dolby

Pro

Logic

Surround

Sound

system.

This

system

is

similar

to

professional

Dolby

stereo

decoders

used

in

and

the

effect

is

more

realistic

than

the

conventional

_

Тре

Dolby

Pro

Logic

Surround

Sound

system,

by

employing

а

four-

_

channel

system,

divides

the

input

signals

into

four

levels:

the

left

and

right

main

channels,

the

center

channel

(to

characterize

dialogue),

and

the

rear

surround-sound

channels

(to

characterize

sound

effects,

background

noise

and

other

ambient

noise).

As

a

result,

compared

to

the

conventional

3-channel

surround-sound

system,

the

yield

of

the

true

center

channel

is

added,

thus

even

further

expanding

the

width

of

the

surround-sound

effect.

Dolby

surround-sound

is

encoded

on

the

track

of

commercially

available

cassettes

and

video

discs

as

well.

When

you

play

a

source

encoded

with

Dolby

surround-sound

on

your

home

video

system,

the

Dolby

Pro

Logic

surround

mode

on

this

unit

decodes

the

signal

and

feeds

the
