exampie,

the

appliance

should

not

be

situated

on

a

bed,

sofa,

surface

that

may

block

the

ventilation

openings;

or,

placed

in

a

GROUNDING

Explanation

Neer

eee

ee

a

Surround

System

(TX-906

only)

Many

motion

pictures

produced

in

the

last

decade

have

been

released

in

“Dolby

Stereo”

sound,

with

music,

dialogue,

and

panned

effects

coming

from

the

3-channel

front

soundstage,

and

surround

effects

and

ambience

emmanating

from

the

sides

and

rear

of

the

theater.

These

four

channels

are

encoded,

or

matrixed,

into

a

two-channel

DOLBY

STEREO

release,

and

decoded

in

the

theater

by

a

professional

DOLBY

STEREO

MP

(Motion

Picture)

decoder.

These

surround

sound

effects

are

“hidden’

in

the

two-channel

stereo

movie

release,

and

decoded

in

the

theater

by

special

Delby

equipment.

These

same

two-channel

motion

picture

masters

are

used

for

production

of

stereo

VHS,

VHS-HIi-Fi,

Beta

Hi-Fi,

and

stereo

Laser

Vision

discs

that

you

can

buy

or

rent

at

your

video

store.

The

TX-906

incorporates

the

Dolby

Pro

Logic

Surround

Circuit,

which

is

designed

to

emulate

the

audience

experience

found

in

DOLBY

STEREO

theaters.

Like

DOLBY

SURROUND,

DOLBY

PROLOGIC

SURROUND

is

capable

of

creating

a

multi-dimensional

soundstage,

but

with

the

increased

channel

separation

it

gives

a

far

greater

sense

of

“movement”

and

sound

localization.

Just

like

in

the

theater,

the

addition

of

the

active

center

channel

ensures

that

ail

audience

members

hear

dialogue

coming

from

its

on-screen

sources

regardless

of

seating

position.

Since

the

TX-906

is

equipped

with

a

front

amplifier

and

a

rear

(surround)

power

amplifier,

Dolby

Pro

Logic

Surround

and

Hall,

effects

can

all

be

produced.

You

can

enjoy

the

feeling

of

a

movie

theater

or

concert

hal!

in

your

own

room.

To

reproduce

these

effects,

rear

(surround)

speakers

and

center

speakers

are

necessary.

The

placement

of

these

speakers

is

important.

You

can

experiment

with

various

positions

and

locations

to

find

the

best

placement

for

optimum

sound

quality

in

your

roam.

*

The

TX-906

comes

without

a

center

power

amplifier.

Use

a

power

amplifier

with

a

power

rating

equal

to

or

better

than

the

front

amplifier

of

the

TX-906.

Without

a

center

power

amplifier,

you

can

add

the

Dolby

Pro

Logic

Surround

Sound

effect

to

the

playback,

by

setting

the

center

mode

to

PHANTOM.

(TX-906

only)

When

using

video

cassette

tapes

or

video

discs

that

have

the

DOLBY

STEREO

or

DOLBY

SURROUND

trade

mark,

you

can

achieve

the

same

kind

of

sound

in

your

room

that

you

experience

in

a

movie

theater.

The

main

Dolby

Pro

Logic

Surround

functions

are

sent

through

the

center

channel.

Because

of

this,

three

modes

must

be

available

from

the

speaker

and

the

center

amplifier

used

by

the

center

channel.

1.

Normal:

When

a

small

speaker

is

used

on

the

center

channel,

signais

of

100

Hz

or

more

are

output

from

the

center

speaker,

and

signals

of

100

Hz

or

less

are

split

between

the

front

L

and

R

channels.

2.

Wide

band:

When

the

front

L

and

R

channels

are

using

similar

speakers

on

the

center

channel,

it

operates

throughout

the

full

frequency

range.

3.

Phantom:

When

no

center

speaker

is

used,

the

center

channel

signal

is

split

between

the

front

L

and

R

speakers,

producing

the

same

resuits

as

found

with

a

center

speaker.

®

Hall

In

most

cases,

the

same

kind

of

sound

that

you

experience

in

a

theater

or

concert

hall,

and

the

natural

expansion

of

sound,

can

be

achieved

with

a

music

source.

®

The

remote

controi

transmitter

is

powered

by

two

batteries.

Before

using

this

unit

for

the

first

time,

insert

the

two

batteries

(included)

as

shown

in

the

diagram.

@

Average

battery

life

is

about

one

year.

This

period

may

be

shorter

depending

on

the

frequency

of

use

and

environment

(temper-

ature

and

humidity)

in

which

the

remote

control

transmitter

is

used.

@

if

the

remote

control

transmitter

does

not

operate

even

though

front

controls

function

normally,

the

batteries

should

be

replaced.

Use

only

batteries

listed

in

the

following

chart.

Do

not

leave

an

expired

battery

in

the

case

as

it

may

leak

or

damage

the

battery

case.

When

inserting

the

batteries,

be

sure

the

(+)

and

(~)

ends

are

properly

aligned.

Do

not

use

nickel-cadmium

(rechargeable)

batteries.

Do

not

use

one

specified

(manganese)

battery

and

one

al-

kaline

Battery

at

the

same

time.

Replace

both

batteries

at

once;

do

not

use

one

old

and

one

new

battery

together.

Using

1.

The

batteries

of

the

must

be

replaced

periodically.

2.

This

unit

uses

infrared

rays.

Therefore,

commands

may

not

be

received

properly

if

the

front

panel

of

this

unit

is

exposed

to

bright

light.

To

prevent

this

from

occurring,

place

this

unit

so

that

it

is

not

directly

exposed

to

bright

light.

3.

If

this

unit

is

placed

inside

an

audio

rack

behind

a

glass

door,

the

door

should

not

have

colored

glass

or

have

any

decorations

on

it,

since

this

could

shorten

the

range

or

prevent

commands

from

being

received.

4.

The

transmitter

operates

up

to

a

distance

of

about

five

meters

(16

A

built-in

memory

back-up

system

preserves

the

contents

of

the

memory

during

power

failures

and

even

when

after

the

has

been

varies

depending

on

climate

and

On

the

average,

memory

are

protected

over

a

period

of

a

few

after

the
