Delay

time:

For

the

various

surround

sound

modes,

the

surround

sound

information

is

delayed

slightly,

in

order

to

compensate

for

the

physical

layout

of

your

home

theater

speakers.

This

delay

ensures

that

the

main

sounds

from

the

front

speakers

and

the

surround

sounds

from

the

surround

speakers

arrive

at

the

listening

position

properly

synchronized.

If

the

delay

is

not

set

correctly,

the

surround

sound

effect

is

not

nearly

so

pleasing,

and

in

fact

can

be

distracting

and

annoying.

The

correct

method

to

calculate

the

surround

sound

delay

is

as

follows:

1.

Measure

the

distance

from

the

listening/viewing

position

to

the

plane

of

the

front

speakers

and

note

the

result.

For

example,

we

will

use

a

10

foot

measurement

from

the

listener's

chair

to

the

front

speakers.

2.

Measure

the

distance

from

the

listening

position

to

the

location

of

the

surround

speakers.

Ideally,

the

surround

speakers

will

be

mounted

high

up

on

the

side

walls

immediately

to

the

left

and

right

of

the

listening

position.

For

our

example,

we

will

use

a

5

foot

measurement

from

the

listening

position

to

the

surround

speakers.

3.

Subtract

the

surround

distance

from

the

front

distance.

The

result

is

the

correct

setting

for

proper

delay

time,

in

milli

-seconds.

For

our

example:

10

feet

minus

5

feet=5.

5

msec

of

delay

will

achieve

the

proper

surround

decoding

result.

The

relation

between

the

selected

It

is

widely

misunderstood

that

lots

of

delay

time

is

somehow

preferable

to

a

small

amount

of

delay

time.

This

is

not

the

case.

The

amount

of

surround

delay

time

is

calculated

so

that

the

arrival

time

of

the

surround

sound

to

the

ears

is

"sync"

with

the

arrival

time

of

the

front

sounds

to

the

ears.

By

overly

increasing

the

delay

time

of

the

surround

channel,

this

optimum

sound

arrival

synchronization

is

altered,

and

the

surround

sound

becomes

"detached"

from

the

main

sound,

destroying

the

spatial

aspects

of

the

surround

sound.

The

Dolby

delay

tithe

adjustment

of

0

to

15

msec

allows

for

a

wide

variety

of

home

theater

set-ups,

room

sizes,

and

listening

positions.
