Daily use

When you have ﬁnished setting

up the loudspeakers as described

on the following pages, connect

the entire system to the mains.

The indicator lights turn red, to

indicate that the loudspeakers

are in standby mode, ready for

use. The loudspeakers are

designed to be left in standby

mode when not in use.

Cleaning the loudspeaker

The speaker panels may be cleaned

with a vacuum cleaner set to the

lowest suction level. Clean the other

surfaces using a soft, lint-free cloth

which you have dipped in luke-

warm water and wrung ﬁrmly.

Never use alcohol or other solvents

to clean any parts of the loud-

speaker!

Switching on and off

When you switch on your system,

the loudspeakers switch on simul-

taneously, and the indicator lights

turn green.

When you switch off your audio

(or video) system the indicator

lights turn red.

However, if the loudspeakers are

connected to a computer – via the

LINE IN socket, and with the LINE IN

switch set to PC – they will not

switch to standby. Refer to ‘Cable

connections’ (pp. 6–7).

Indicator light: In daily use the

indicator light shines either red

(standby) or green (playing).

NOTE! Prolonged listening at high

volume levels may cause hearing

damage.

Set up the loudspeakers

We recommend that you follow

this procedure:

– Disconnect your system from the

mains.

– Connect the loudspeakers and set

the LINE IN–POWER LINK switch

on each loudspeaker as explained

in ‘Cable connections’ (pp. 6–7).

– Set the POSITION switch to the

correct setting on each loud-

speaker. This is explained in ‘Adapt

the loudspeaker to your room’

(pp. 8–10).

– Connect the entire system to the

mains again.

The loudspeaker must be placed

standing upright on its base, or

fastened to one of the optional

accessories. Make the connections,

and set both switches before you

fasten the loudspeaker to one of the

accessories.

Cautions

– Make sure that the loudspeakers

are placed and connected in

accordance with the instructions

in this Guide. To prevent injury,

use Bang & Olufsen approved

stands and wall brackets only!

– The loudspeaker can only be

switched off completely by

disconnecting it from the wall

socket.

– Do not attempt to open the loud-

speaker. Leave such operations to

qualiﬁed service personnel! The

speaker panels, however, may be

removed for cleaning.

– The loudspeaker is designed for

indoor use in dry, domestic

environments only, and for use

within a temperature range of

10–40º C (50–105º F).

– For optimum sound quality, do not

place the loudspeaker enclosed in,

for example, a small bookcase.

Leave a minimum of 20 cm (8")

free space at the sides, and never

place anything directly in front of

the loudspeaker.

– Do not block the sound emitting

from the bass reﬂex port at the

bottom of the loudspeaker.

– Place the loudspeaker with its

front (the Bang & Olufsen name

plate) facing your favourite

listening position.

Loudspeaker front and side

panels

With each loudspeaker you will get

one front panel and two side panels.

These panels must be fastened to

the loudspeaker before use.

The front panel is marked with a

Bang & Olufsen name plate. Each

of the panels have three small pegs

on the rear.

Fasten the panels by inserting the

three pegs into the corresponding

holes (A–B) in the front and the

sides of the loudspeaker.

Note: The product identification

and CE labels are placed on the

loudspeaker body behind the side

panels.

Ceiling Bracket: This optional

accessory has a hidden lock, which

must be released before you can

detach the loudspeaker from the

ceiling.

Use a small screwdriver, for example,

to push the lock inwards, while

turning the loudspeaker counter-

clockwise until it is free.

Cable connections

The loudspeakers can be used

with Bang & Olufsen audio,

video and link systems. They

may also be used with non-

Bang & Olufsen audio or video

systems, or connected to a

computer.

About the two switches …

The POSITION switch has three

settings. Which setting to use

depends on the position of the loud-

speaker. This is explained in ‘Adapt

the loudspeaker to your room’

(pp. 8–10).

The LINE IN–POWER LINK switch

serves two purposes. If the loud-

speaker is connected to the system

via the LINE IN socket, it switches

between two line input levels. If

connected via the POWER LINK

socket, it switches between the

right and left sound channel.

Connection to Bang & Olufsen

systems

Use Power Link cables to connect

the loudspeakers to your system.

Set the POWER LINK switch to

RIGHT or LEFT, the right and left

sound channel, respectively.

Connection to non-Bang &

Olufsen systems …

… To audio or video systems

Connect the system to the LINE IN

socket on each loudspeaker (mini-

jack – mono).

Set the LINE IN switch to LINE.

… To a personal computer

Use a special connector to connect

the computer sound card output to

each of the LINE IN sockets on the

loudspeakers (the connector is avail-

able as an optional accesory from

your Bang & Olufsen retailer).

Set the LINE IN switch to PC.

When set to PC, the loudspeakers

will not automatically switch to

standby mode when the sound

signal disappears. In this case, we

recommend that you switch off at

the wall socket, when not using the

computer.

RIGHT LEFT - POWER LINK

POWER LINK ~

The sockets and the two switches

are located in the base of the loud-

speaker.

Power Link connections: These

connections carry both the right

and left sound signals. Therefore,

you can:

1Run a Power Link cable from the

Bang & Olufsen system directly

to each loudspeaker.

2 Use a Power Link adapter (optional

accessory, available from your

Bang & Olufsen retailer). Run a

cable from the Bang & Olufsen

system to the ﬁrst loudspeaker,

and then run another cable from

the ﬁrst loudspeaker to the next.

This will often help to minimise

cable clutter.

Cable Clamp: For safety reasons,

the mains lead must be secured to

the loudspeaker with the cable

clamp provided. The cable clamp

holds both the mains lead and the

loudspeaker cable.

Power Link cables: The Power Link

cables must be of the new type

(marked with a triangle on the plug).

Do not use any old type Power Link

cables, as this will cause noise, and

thus not give optimum sound

quality!

Adapt the loudspeakers to your room

When a loudspeaker is placed

in a corner, or close to a wall or

ceiling, the bass level is boosted

compared to the bass level

achieved from a loudspeaker

placed in a more free-standing

position.

Use the POSITION switch to

ensure that the bass level suits

the placement of the loud-

speaker. The appropriate switch

setting depends on the distance

from the loudspeaker to the

walls, ceiling and corners of the

room.

Use the guidelines mentioned here,

and the illustrations on the next

two pages, when deciding which

of the three POSITION switch

settings to select – on each loud-

speaker.

… Placed on a floor stand

Use POSITION 1 if the loudspeaker

is placed more than 50–70 cm (20–

28") from a side wall (inside the

light grey zone).

Use POSITION 3 if the loudspeaker

is placed closer to a side wall

(inside the darkest grey zone).

… Placed on the wall

Use POSITION 1 if the loudspeaker

is placed more than 50–70 cm (20–

28") from a side wall, and more

than 50 cm (20") below the ceiling

(inside the light grey zone).

Use POSITION 2 if the loudspeaker

is placed less than 50 cm (20")

below the ceiling (inside the darker

grey zone).

Use POSITION 3 if the loudspeaker

is placed inside the darkest grey

zone.

… Placed on the ceiling

Use POSITION 1 if the loudspeaker

is placed more than 50–70 cm (20–

28") from a side wall, and more

than 50 cm (20") from the rear

wall (inside the light grey zone).

Use POSITION 2 if the loudspeaker

is placed less than 50 cm (20")

from the rear wall (inside the

darker grey zone).

Use POSITION 3 if the loudspeaker

is placed inside the darkest grey

zone.

… Standing on a table

Use POSITION 1 if the loudspeaker

is placed more than 50–70 cm (20–

28") from a side wall, and more

than 50 cm (20") from the rear

wall (inside the light grey zone).

Use POSITION 2 if the loudspeaker

is placed less than 50 cm (20")

from the rear wall (inside the

darker grey zone).

Use POSITION 3 if the loudspeaker

is placed close to both the rear wall

and a side wall (inside the darkest

grey zone).

Position zones: The POSITION

switch has three settings marked 1,

2, and 3. The settings corresponds

to the position zones shown here.

The distances are meant as guide-

lines, and you may, of course, set

the POSITION switch to any of the

three settings you prefer.

Example 1: This illustration shows

the position zones projected onto

the wall behind the loudspeakers, as

seen from your favourite listening

position. The two loudspeakers –

on floor stands – are placed within

position zone 1 (light grey zone),

and therefore the POSITION switch

should be set to 1on both loud-

speakers.

>> Adapt the loudspeaker to your room

Example 2: This illustration shows

the position zones projected onto

the ceiling. The loudspeakers – on

ceiling brackets – are placed within

position zone 2 (darker grey zones),

and therefore the POSITION switch

should be set to 2on both loud-

speakers.

If you have a BeoLab 2 sub-

woofer setup …

As explained in the BeoLab 2

Guide, the subwoofer has a SETUP

switch which can be set to 1, 2,

or 3. This will adapt the output

from BeoLab 2 to the sensitivity

levels of different loudspeakers.

If you connect a pair of BeoLab 4

loudspeakers to the BeoLab 2 sub-

woofer, we recommend that you

set the BeoLab 2 SETUP switch

to position 2.
