ual

taste

and

the

acoustic

conditions

in

your

listening

room

or

home

theater.

The

factory

setting

is

appropriate

for

most

rooms,

but

some

installations

cre-

ate

an

uncommon

distance

between

the

front

and

surround

speakers

that

may

cause

the

arrival

of

front

channel

sounds

to

become

disconnected

from

surround

channel

sounds.

To

re

-synchronize

the

front

and

surround

channels,

follow

these

steps:

1.

Measure

the

distance

from

the

lis-

tening/viewing

position

to

the

front

speakers.

2.

Measure

the

distance

from

the

lis-

tening/viewing

position

to

the

sur-

round

speakers.

3.

Subtract

the

distance

to

the

sur-

round

speakers

from

the

distance

to

the

front

speakers

and

add

15.

The

resulting

number

is

the

ideal

delay

time

for

your

room.

For

example,

if

the

front

speakers

are

10

feet

away

and

the

surround

speakers

are

5

feet

away,

the

formula

will

be

"10-5+15=20".

Thus,

the

correct

delay

time

in

this

room

would

be

20ms.

NOTE:

The

delay

time

may

only

be

adjusted

in

certain

modes.

If

the

delay

time

needs

to

be

changed,

it

may

be

increased

by

pressing

the

DELAY

button

Eg

(13

on

the

front

panel.

The

delay

time

will

be

briefly

displayed

on

the

video

menus

as

well

as

the

front

panel.

In

addition

to

the

use

of

the

delay

time

formula,

it

is

a

good

idea

to

understand

the

features

of

each

of

the

AVR80/Ts

sur-

round

modes

when

entering

delay

time.

The

chart

on

the

next

page

provides

an

explanation

of

the

suggested

for

each

mode.

The

chart

also

contains

the

delay

time

limits

for

each

of

the

modes.

Direct

Digital

Decoding

The

AVR80/ts

digital

signal

processing

uses

sophisticated

microprocessors

and

advanced

digital

audio

engines

that

manipulate

sound

in

the

digital

domain.

In

order

to

work

with

sound,

these

cir-

cuits

must

first

convert

the

incoming

analog

audio

input

to

a

digital

signal.

After

processing,

the

digital

audio

signal

must

be

converted

back

to

analog

for

vol-

ume

control

and

amplification.

While

the

digital

to

analog

(D/A)

and

analog

to

digital

(A/D)

circuits

in

the

AVR80//

are

high

quality,

any

time

an

audio

signal

is

digitized

or

reconstructed

to

analog

there

is

the

possibility

of

quali-

ty

loss.

This

helps

you

to

avoid

un-needed

A/D

and

D/A

conversion

from

any

laser

disc

player

equipped

with

a

coaxial

digi-

tal

output.

If

your

player

has

this

type

of

output,

connect

the

LD

player

to

the

AVR80//

with

a

high

quality

digital

or

coax

intercon-

nect.

The

connection

should

be

made

to

the

LD

DIGITAL

IN

jack

gi

on

the

rear

panel.

Once

this

connection

is

made,

the

AVR80//

will

accept

the

digital

output

directly

from

your

LD

player.

To

select

the

direct

digital

input,

press

the

LD

button

and

hold

it

for

three

seconds.

This

means

that

audio

signals

will

remain

in

their

pure

digital

state

until

after

all

sur-

round

processing

has

taken

place.

NOTE:

This

connection

is

for

standard

two

channel

44.1

kHz

PCM

digital

audio,

as

provided

by

LD

or

CD

machines.

It

is

NOT

an

input

for

multichannel

digital

audio

signals

such

AC

-3

or

DTS.

Improper

connection

to

the

wrong

type

of

digital

output

may

cause

damage

to

the

AVR80//

or

other

components

in

your

audio

system

and

are

not

covered

by

the

AVR80//

war-

ranty.

Consult

your

dealer

or

installer

if

you

have

any

questions

about

this

input.

6

Channel

Direct

Operation

Since

1993,

an

increasing

number

of

theatrical

motion

pictures

have

been

recorded

with

digital

sound

tracks.

With

these

new

processes

such

as

Dolby

Surround

Digital',

DTS®

and

Sony's

SDDS°,

five

or

more

discrete

sound

channels

are

available

along

with

a

dedi-

cated

subwoofer

channel

for

low

frequen-

cy

sounds.

The

replacement

of

analog

matrix

theatrical

audio,

such

as

Dolby

Stereo

with

these

new

systems

has

greatly

increased

the

enjoyment

of

movie

sound.

Advances

in

electronics

technology

now

make

it

possible

to

bring

these

discrete

digital

audio

soundtracks

into

your

home.

Many

of

today's

new

LD

players

and

an

increasing

number

of

LD

movie

releases

provide

for

Dolby

Digital

sound-

tracks.

In

the

future,

high

definition

tele-

vision

(HDTV)

broadcasts

will

also

carry

multichannel

digital

audio

information.

To

prevent

your

AVR80//

from

obsoles-

cence,

special

jacks

are

provided

for

use

with

external

multichannel

audio

adapters.

If

an

adapter

such

as

the

Harman

Kardon

ADP303

is

installed

in

your

sys-

tem,

connect

its

six

analog

audio

outputs

to

the

6

-CH

DIRECT

INPUT

jacks

®

on

the

AVR80/Ts

rear

panel.

When

listening

to

programs

using

an

external

adapter,

press

the

6

-CH

DIRECT

button

©Ea

on

the

remote

or

front

panel.

All

surround

processing

will

be

disabled

when

6

Channel

Direct

is

in

use,

as

none

is

required

with

discrete

audio

signals.

Volume

is

controlled

in

the

normal

fashion.

NOTE:

Audio

reproduced

from

the

6

Channel

Direct

inputs

may

not

be

recorded.
