Connect

the

bass

module

to

your

receiver

or

amplifier.

Caution:

Be

sure

the

receiver

is

turned

off

and

unplugged

from

the

power

source

before

making

these

connec-

tions.

You

will

use

the

remaining

three

cables

to

connect

the

module

to

the

receiver.

Remember

that

the

red

banded

(white

or

grey

striped)

wire

is

positive

(+)

and

connects

to

a

positive

(red)

terminal.

Attach

one

end

of

one

cable

to

one

set

of

INPUTS

FROM

RECEIVER

OR

AMPLI-

FIER

terminals

on

the

Acoustimass"

bass

module.

with

the

remaining

two

cables.

Now,

connect

the

free

end

of

each

of

the

cables

to

your

receiver's

speaker

terminals.

Make

the

L

and

R

connections

to

the

FRONT

receivers

provide

terminals

for

more

than

one

pair

of

front

speakers.

Sometimes

these

are

labeled

Speaker

A

and

Speaker

B.

Use

either

set

of

termi-

nals,

unless

one

is

designated

fora

particular

ohm

rating.

!f

so,

choose

the

terminals

indicated

for

use

with

speakers

rated

8

ohms

(8(2)

or

less.

Bose

has

engineered

the

Acousti-

mass-4

home

theater

speaker

system

to

work

with

surround

sound

receivers

that

provide

an

amplified

center

channel.

If

your

receiver's

center

channel

is

not

amplified,

you

Can

still

obtain

full

performance.

To

do

so,

use

an

RCA

cable

to

connect

an

amplifier

to

your

receiver.

Run

the

cable

from

the

receiver's

center

channel

RCA

-type

output

terminal

to

the

RCA

-type

input

on

the

amplifier.

On

a

stereo

amplifier

there

are

two

inputs;

use

either

one.

Then

connect

the

center

channel

INPUTS

FROM

RECEIVER

OR

AMPLIFIER

on

the

Acoustimass

module

to

the

amplifier,

instead

of

to

the

receiver.

The

Acoustimass-4

home

theater

speaker

system

is

designed

to

provide

pure, natural

sound

reproduction

in

•

audio

as

well

as

video

applications.

Refer

to

your

receiver

owner's

guide

for

a

description

of

audio

operations.
