READ

THIS

BEFORE

OPERATING

YOUR

UNIT

CONNECTIONS

TO

THE

AMPLIFIER

•

In

order

to

maintain

the

speaker

cabinet's

finish,

prevent

it

from

coming

into

contact

with

water

vapor,

alcohol,

benzene,

insecticide,

etc.

To

clean,

wipe

with

a

dry,

soft

cloth.

•

To

prevent

the

enclosure

from

warping

or

discoloring,

do

not

place

the

speaker

in

places

•

Before

making

connections,

make

sure

that

the

amplifier

is

switched

off.

■

CONNECTIONS

where

it

will

be

exposed

to

direct

sunlight

or

excessive

humidity.

•

Using

speaker

cable

supplied,

connect

the

speaker

output

terminals

of

the

receiver/amplifier

and

the

input

terminal

of

the

speakers.

•

Do

not

place

the

speakers

where

they

are

liable

to

be

knocked

over

or

struck

by

falling

objects.

Stable

placement

will

also

ensure

better

sound

performance.

•

Connect

the

(+)

terminals

on

both

receiver/amplifier

and

speaker.

Connect

the

(-)

terminals

on

both

receiver/amplifier

and

speaker.

•

Never

touch

the

speakers

under

the

grille

cloth

with

your

hands

or

expose

them

to

excessive

shocks.

If

they

are

dented

or

bent,

the

sound

will

be

distorted

as

well.

•

Reversing

polarity

(+/-)

will

result

in

unnatural

sound

reproduction.

•

When

an

amplifier

with

a

rated

output

power

higher

than

the

recommended

power

of

the

speaker

system

is

used,

care

should

be

taken

never

to

exceed

the

speaker's

maximum

■

PROCEDURE

input.

1.

Press

the

lever

on

the

speaker

terminal

down,

as

shown

in

the

diagram.

•

Lower

the

power

amplifier/receiver

volume

control

before changing

input

sources.

Never

change

input

sources

(for

example,

FM

to

CD)

at

high

listening

levels.

Always

turn

the

receiv-

er/amplifier

unit

off

when

installing

or

removing

input

cables.

2.

Insert

the

bare

wire

end

of

the

speaker

cable

into

the

terminal.

3.

Remove

your

finger

from

the

lever

to

allow

it

to

lock

snugly

on

the

cable's

wire

end.

•

Anytime

you

note

distortion,

reduce

the

volume

control

on

your

power

amplifier/receiver

to

a

lower

setting.

Never

allow

your

power

amplifier

to

be

driven

into

"clipping."

4.

Test

the

security

of

the

connection

by

tugging

lightly

on

the

cable

at

the

terminal.

•

Connections

to

the

amplifier

speaker

terminals

depend

on

the

particular

amplifier

you

are

using.

Please

check

the

amplifier's

owner's

manual

before

making

speaker

connections.

5.

Repeat

for

all

wires.

(Note:

owner's

manual.)

For

receiver/amplifier

connections,

please

refer

to

proper

area

lever

•

Before

making

any

connections

to

the

speaker

system

or

amplifier,

make

sure

to

turn

off

the

power

of

the

amplifier

to

avoid

any

damage.

Right

Speak

Left

Speaker

•

These

speakers

feature

a

magnetically

shielded

design,

but

there

is

still

a

chance

that

placing

them

too

close

to

a

TV

set

might

impair

the

picture colors.

Should

this

happen,

place

the

speaker

away

from

the

TV

set.

TYPE

OF

AMPLIFIER

/

RECEIVER

These

Natural

Sound

Home

Theater

Entertainment

Speakers

are

designed

to

compliment

any

of

Yamaha's

receivers

or

amplifiers.

To

assure

low

distortion

on

program

peaks,

the

amplifier

or

receiver

should

be

capable

of

delivering

at

least

10

watts

(continuous

sine

-wave

power)

per

channel.

These

speakers

can

be

used

safely

with

amplifiers

rated

at

up

to

the

maximum

wattage

shown

in

the

specifications

table.

Amplifiers

rated

at

higher

than

the

recommended

maximum

power

per

channel

may

be

used

with

care.

Program

material

is

not

a

continuous

sine

-wave

input,

and

even

with

a

100

watt

amplifier,

average

levels

will

remain

somewhere

between

1/10

-watt

and

10

watts.

If

you

do

use

a

large

amplifier,

be

careful

never

to

change

input

sources

before

reducing

the

volume

level

to

prevent

transients

from

damaging

your

speaker.

AN

RECEIVER/AMPLIFIER

TO

MAIN

SPEAKER

CONNECTION

SPEAKER

PLACEMENT

This

speaker

is

a

wide

dispersion

design

and

it

performs

well

in

almost

any

location.

Preferably,

the

speaker

should

be

placed

on

a

sturdy,

vibration

-free

surface.

For

stereo

listening,

the

main

speakers

should

be

placed

approximately

6

to

8

feet

apart

in

front

of

the

listening

area.

If

speakers

are

to

be

used

as

surround

sound

speakers,

ideally

these

speakers

should

be

placed

behind

the

listening

area.

(i.e.

on

bookshelves

or

end

tables).

Location

should

be

6-10

feet

apart

and

at

ear

level

or

preferably

higher.
