Sound

Adjustment

Hints

for

adjusting

the

parameters

•

Wall

material

simulation

(WALL)

When

sound

is

reflected

off

soft

material,

such

as

a

curtain,

the

high

frequency

elements

are

reduced.

A

hard

wall

is

highly

reflective

and

does

not

significantly

affect

the

frequency

response

of

the

reflected

sound.

The

WALL

parameter

lets

you

control

the

level

of

the

high

frequencies

to

alter

the

sonic

character

of

your

listening

environment

by

simulating

a

softer

(SOFT),

or

harder

(HARD)

wall.

The

midpoint

designates

a

neutral

wall

(made

of

wood).

•

Seat

position

simulation

(SEAT)

(FRONT/REAR

and

LEFT/RIGHT)

If

you

sit

in

the

front

of

a

room,

you

hear

more

direct

sound

from

the

front

speakers.

As

you

move

to

the

rear,

the

reflected

sound

increases.

Similarlq,

the

reflected

sound

changes

when

you

move

from

left

to

right,

and

vice

versa.

The

FRONT/REAR

and

LEFT/RIGHT

parameters

let

you

control

the

balance

of

direct

and

reflected

sound

to

simulate

your

listening

position.

In

the

FRONT/REAR

parameter,

"F"

signifies

the

front

of

the

room

and

"R"

signifies

the

rear.

The

midpoint

designates

the

center.

In

the

LEFT/RIGHT

parameter,

"L"

signifies

the

left

side

of

the

room

and

"R"

signifies

the

right

side.

The

midpoint

designates

the

center.

•

Reverberation

time

(REVERB)

This

parameter

adjusts

the

length

of

time

required

for'

the

reverberation

(echoes)

generated

from

a

given

sound

to

attenuate

—60

dB.

You

can

choose

shorter

(S)

or

longer

(L)

reverberation

times.

•

Low

Frequency

Extension

(LFE)

mix

level

(OTHER)

This

parameter

lets

you

attenuate

the

level

of

the

LFE

(Low

Frequency

Extension)

channel

output

from

the

sub

woofer

without

effecting

the

level

of

the

bass

frequencies

sent

to

-the

sub

woofer

from

the

front,

center

or

rear

channels

via

the

bass

redirection

circuitry.

The

level

can

be

adjusted

in

0.5

dB

steps

from

-20.0

dB

to

0

dB

(line

level).

0

dB

outputs

the

full

LFE

signal

at

the

mix

level

determined

by

the

recording

engineer.

Selecting

MUTE

mutes

the

sound

of

the

LFE

channel

from

the

sub

woofer.

However,

the

low

frequency

sounds

of

the

front,

center,

or

rear

speakers

are

output

from

the

sub

woofer

according

to

the

settings

made

for

each

speaker

in

the

speaker

setup

(page

22).

•

Dynamic

range

compression

ratio

(OTHER)

Lets

you

compress

the

dynamic

range

of

the

sound

track.

This

may

be

useful

when

you

want

to

watch

movies

at

low

volumes

late

at

night.

OFF

reproduces

the

sound

track

with

no

compression.

STD

reproduces

the

sound

track

with

the

full

dynamic

range

as

intended

by

the

recording

engineer.

0.1

-

0.9

allow

you

to

compress

the

dynamic

range

in

small

steps

to

achieve

the

sound

you

desire.

MAX

provides

a

dramatic

compression

of

the

dynamic

range.

•

Test

tone

(TEST)

This

parameter

emits

the

test

tone

and

allows

you

to

check

the

balance

of

the

speaker

levels.

See

"Adjusting

the

speaker

volume"

on

page

23

for

details.
