Daily use
When you have finished setting up
the loudspeakers as described on
the following pages, connect the
entire system to the mains supply.
The indicators light up in red,
indicating that the loudspeakers
are in standby, ready to be used.
The loudspeakers are designed to
be left in standby mode when not
in use.
Switching on and off
When you switch on your system, the loud-
speakers switch on simultaneously, and the
indicator lights turn green. When you switch
the system off again the loudspeakers also
switch to standby.
Cleaning the loudspeaker
Clean dusty surfaces using a dry, soft cloth.
If necessary, remove grease stains or persistent
dirt with a soft, lint-free cloth which you have
dipped in lukewarm water and wrung rmly.
Never use a vacuum cleaner to clean the
exposed speaker membrane in the acoustic
lens. However, the front cloth may be cleaned
with a vacuum cleaner with a brush nozzle,
and set to the lowest level.
Never use alcohol or other solvents to clean any
parts of the loudspeaker!
Loudspeaker protection
Each loudspeaker is equipped with a thermal
protection system which prevents damage from
overheating. If an error occurs – or the speaker
units become overheated – the system auto-
matically switches the loudspeaker to standby,
and the indicator light turns yellow.
To restore the sound:
> Disconnect the loudspeaker from the mains
supply.
> Allow the system time to reset or cool down
(approximately 3–5 minutes).
>
Reconnect the loudspeaker to the mains supply.
Should the problem persist, contact your
Bang & Olufsen retailer.

The indicator light is positioned behind the
exposed speaker membrane in the acoustic lens.
NOTE! Prolonged listening at high volume
levels may cause hearing damage.

Set up the loudspeakers
We recommend that you follow
this procedure when you set up
the loudspeakers:
– Disconnect your system from the
mains supply.
– Connect your loudspeakers and set
the switch marked LINE–RIGHT–LEFT
on each loudspeaker as explained in
‘Cable connections’ (pp. 6–7).
– Set the switch marked FREE–WALL–
CORNER to the correct setting on
each loudspeaker. This is explained
in ‘Adapt the loudspeakers to your
room’ (pp. 8–9).
– Connect your entire system to the
mains supply again.
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 loudspeakers can only be switched off
completely by disconnecting them from the
mains supply. Therefore, connect the loud-
speakers to an easily accessible wall socket.
– Do not attempt to open the loudspeakers.
Leave such operations to qualified service
personnel!
– The loudspeakers are 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
loudspeakers enclosed in a small space, and
never place anything directly in front of the
loudspeakers.
– Place the loudspeakers with the front facing
your favourite listening position.
5
The loudspeakers must be placed standing
upright on the base on a firm and level surface.

Cable connections
The loudspeakers can be used with
Bang & Olufsen audio, video and
link systems. They may also be
connected to non-Bang & Olufsen
systems.
For specific information about the
sockets on your system, refer to
the Guide enclosed with the system.
Connection panel
FREE–WALL–CORNER switch
This switch has three settings. Which setting
to use depends on the placement of the
loudspeakers. This is explained in ‘Adapt the
loudspeakers to your room’ (pp. 8–9).
LINE–RIGHT–LEFT switch
This switch has three settings. Set the switch
to RIGHT or LEFT, when connecting the
loudspeakers to a Bang &Olufsen system.
Set the switch to LINE when connecting the
loudspeakers to a non-Bang & Olufsen system.
POWER LINK sockets
These sockets are used for connection to a
Bang & Olufsen system. However, if the switch
marked LINE–RIGHT–LEFT is set to LINE, you may
use one of the Power Link sockets to connect
the loudspeaker to a non-Bang & Olufsen system.
~
Socket for connection to the mains supply.
Connection to Bang & Olufsen systems
Use Bang & Olufsen Power Link cables to
connect the loudspeakers to your system.
Set the LINE–RIGHT–LEFT switch to RIGHT
and LEFT (the right and left sound channel),
respectively.
Connection to non-Bang & Olufsen systems
Use a special adapter with an ordinary phono/
RCA plug in one end, and a DIN-plug in the
other (‘Cable for line signal’ – optional accessory,
available from your Bang & Olufsen retailer).
Set the LINE–RIGHT–LEFT switch to LINE.
The supplied plug and mains cord are specially
designed for the product. Do not change the
plug and if the mains cord is damaged, you
must buy a new one from your Bang &
Olufsen retailer.

The sockets and the two switches are located
on the rear of the loudspeaker. Remove the
cover to get access to the sockets and switches.

Securing the cables: For safety reasons, the
mains lead must be fastened to the loudspeaker.
To do so, tug the mains lead behind the small
bracket on the connection panel. Then run all
cables behind the clamp, and tighten the two
screws.
Cover for the connection panel: To remove
the cover, grip it along the left and right edges
– as indicated by the two arrows.
When you have made all the connections and
secured the cables, fasten the cover again by
inserting the four pegs on the rear of the cover
into the corresponding holes on the loudspeaker.
Power Link cables: The cables must be of the
type which are marked with a triangle on the
plug. Do not use any of the old type of Power
Link cables, as this will cause noise, and thus
not give optimum sound quality!
Power Link connections: These connections
carry both the right and left sound signals.
Therefore, you can:
1Run a Power Link cable from your
Bang & Olufsen system directly to
each loudspeaker.
Or
2Run a Power Link cable from your
Bang & Olufsen system to the first
loudspeaker, and then run another
Power Link cable to the next loudspeaker.
This will often help to minimise cable clutter.

Adapt the loudspeakers to your room
The loudspeakers may be placed
almost anywhere in you room.
However, the most natural sound
is obtained if they are set up as
explained on these pages.
The Acoustic Lens Technology
system ensures better balance in
the high tone frequencies coming
directly from each loudspeaker,
and the sound reflected by the
room. The system also ensures
correct tonal balance in the whole
area in front of the loudspeaker.
The FREE–WALL–CORNER switch
When a loudspeaker is placed in a corner
or close to a wall, the bass level is boosted
compared to the bass level from a loudspeaker
placed in a more free-standing position.
To remove this excessive bass boost, set the
switch marked FREE–WALL–CORNER to ensure
that the bass level suits the placement of the
loudspeaker. The appropriate switch setting
depends on the distance from the loudspeaker
to the walls and corners of the room.
Use the guidelines mentioned here, and the
illustration and the examples on the next page,
when deciding which of the three POSITION
switch setting to select – on each loudspeaker.
FREE
Use this setting if the loudspeaker is placed
more than 20 cm (8") from the wall, and no
closer to a corner than 65 cm (26") – shown
by the large light grey area in the illustration
on the next page.
WALL
Use this setting if the loudspeaker is placed less
than 20 cm (8") from the wall, and no closer
to a corner than 65 cm (26") – shown by the
grey areas along the walls in the illustration on
the next page.
CORNER
Use this setting if the loudspeaker is placed in
a corner – shown by the dark grey areas in the
illustration on the next page.

If you have a BeoLab 2 subwoofer setup …
As explained in the BeoLab 2 Guide, the
subwoofer has a setup switch which can be
set to 1, 2or 3. The settings of this switch
will adapt the output from BeoLab 2 to the
sensitivity levels of different loudspeakers.
If you set up a pair of BeoLab 9 loudspeakers in
a system with BeoLab 2, we recommend that
you set the BeoLab 2 SETUP switch to 1.

Position zones: The three settings
(FREE–WALL–CORNER) corresponds to the
position zones marked in different shades of
grey shown here. The position zones and the
examples shown below, are meant as guidelines
– you may, of course, set the switch to any of
the three settings you prefer.
Example 3: As in example 2, one loudspeaker
is placed against the wall, and the other is
placed in a corner. The shape of the room
has no influence on which setting to select.
Therefore, the left loudspeaker should be set
to WALL, and the right loudspeaker should be
set to CORNER.
Example 1: The loudspeakers are placed in
one end of the room, but not against the back
wall, and not near the side walls. Therefore,
the switch should be set to FREE on both
loudspeakers.
Example 2: One loudspeaker is placed against
the wall, and the other is placed in a corner.
Therefore, the left loudspeaker should be set to
WALL, and the right loudspeaker should be set
to CORNER.
