Understanding

the

Digital

Surround

Processor

The

sound

heard

in

a

place

such

as

a

concert

hall

or

a

movie

theater

consists

of

direct

sound,

and

early

reflected

sound

(early

reflections)

and

a

reverberative

sound

(reverberation).

The

acoustics

of

the

room

affect

the

way

these

three

sounds

are

heard.

We

can

estimate

the

size

or

the

type

of

a

hall

by

listening

to

and

differentiating

these

three

kinds

of

sound.

The

STR-GX909ES/STR-GX808ES

reproduces

the

early

reflections

and

the

reverberation

using

its

digital

signal

processor

and

allows

you

to

design

a

variety

of

sound

field

in

your

own

room.

The

unit

incorporates

10

types

of

the

SOUND

FIELD

program,

and

you

can

select

the

desired

SOUND

FIELD

mode

by

pressing

the

SOUND

FIELD

button.

Also

you

can

adjust

several

parameters

within

each

mode

to

maximize

the

effect

in

your

listening

room.
