Center

Width

(MUSIC

mode

of

Dolby

Pro

Logic

II

only)

This

control

allows

center-channel

sounds

to

be

posi-

tioned

between

the

center

speaker

and

the

left/right

speakers

over

a

range

of

eight

steps.

Step

"3"

uses

a

combination

of

all

three

front

speakers

to

give

the

best

vocal

imaging

and

most

seamless

soundstage

presen-

tation,

and

is

recommended

for

most

recordings.

Step

"0"

places

all

center

sound

in

the

center

speaker.

Step

"7"

places

all

center

sound

equally

in

the

left/right

speakers,

just

as

in

conventional

stereo.

DIMENSE

(MUSIC

mode

of

Dolby

Pro

Logic

II

only)

This

control

allows

the

user

to

gradually

adjust

the

soundfield

either

towards

the

front

or

the

rear.

This

can

be

useful

to

help

achieve

the

desired

balance

from

all

the

speakers

with

certain

recordings

that

may

contain

either

too

much

or

too

little

spatial

effect.

Step

"0"

is

the

recommended

setting,

which

has

no

effect

on

the

sound.

Steps

1,

2,

and

3

gradually

move

the

sound

for-

ward,

and

steps

--1, --2,

and

--3

move

the

sound

towards

the

surrounds.

PANORAMA

(MUSIC

mode

of

Dolby

Pro

Logic

II

only)

This

control

extends

the

front

stereo

image

to

include

the

surround

speakers

for

an

exciting

"wraparound"

effect

with

side-wall

imaging.

It

is

particularly

effective

for

recordings

which

have

strong

left-

or

right-channel

elements

in

the

mix,

as

these

are

detected

and

accen-

tuated

by

the

Panorama

process.
