Dolby

Pro

Logic

Surround

Decoding

system

of

Dolby

Surround

sound

standardized

in

TV

programs

and

movies.

Compared

with

the

former

Dolby

Surround

system,

Dolby

Pro

Logic

Surround

improves

sound

image

by

using

four

separate

channels:

off-screen

audio

effects,

on-screen

dialog,

left-to-right

panning,

and

music.

These

channels

manipulate

the

sound

to

be

heard

and

enhance

the

action

as

it

happens

on

the

screen.

To

take

advantage

of

Dolby

Pro

Logic,

you

should

have

at

least

one

pair

of

rear

speakers

and/or

one

center

speaker.

You

also

need

to

select

the

appropriate

center

made

to

|

enjoy

a

full

effect.
