Daily use

3

When you have nished setting
up the subwoofer as described
on the following pages,
connect the entire system to
the mains supply. The indicator
lights up in red, indicating that
the subwoofer is in standby,
ready to be used. The
subwoofer is designed to be
left in this standby mode when
not in use.

NOTE! The subwoofer is
designed to protect itself if the
active speaker unit becomes
overheated. The subwoofer
protec tion circuit may become
active after a period of playing
at a high volume level.

Switching on and off – indicator

When you switch on your Bang&

Olufsen system, the subwoofer
switches on simultaneously. The red
standby indicator light turns green,
indicating that the subwoofer is
switched on.

When you switch off your system,
or mute the sound, the red indicator
light appears immediately, indicating
that the subwoofer is not in use.

Subwoofer protection

If the active speaker unit becomes
over heated, the subwoofer will
instantly reduce the sound level.
Once the situation has stabilised,
the sound level is slowly returned to
normal. If the subwoofer is played
constantly at a very high volume
level, it will eventually mute the
sound completely.

Should the subwoofer mute the
sound, the indicator light turns
orange.

Cleaning the subwoofer

Wipe dust off the surfaces using a
dry, soft cloth. If necessary, remove
stains or dirt with a soft, damp
cloth and a solution of water and
mild detergent such as washing-up
liquid.

Never use alcohol or other solvents
to clean any part of the subwoofer!

NOTE! Prolonged listening at high
volume levels may cause hearing
damages.

To restore the sound:

> Disconnect the subwoofer from

the mains.

> Allow the active speaker unit

time to cool off.

> Reconnect the subwoofer to the

mains.

Should the problem persist,

contact your Bang& Olufsen

retailer.

the guidelines in ‘Adapt the

subwoofer to your setup’ (p.8).

For information on how to fasten
the subwoofer to the optional
accessories, refer to the Guide
enclosed with the accessory.

in this Guide. To prevent injury,

use Bang & Olufsen approved

stands and wall brackets only!

– The subwoofer can only be

switched off completely by
disconnecting it from the wall
socket.

the subwoofer units.

– The subwoofer is designed for

indoor use in dry, domestic
environments only, and for use
within a temperature range of

10–40º C (50 –105º F).

– Remember that all speakers in a

setup must be connected to a
mains outlet, and that they are
designed to be connected to the
mains at all times, as this allows
them to switch on automatically.

Adapt the subwoofer to your setup

Placement is exible and easy
with the subwoofer. Due to its
relative small size it can easily
be integrated in most home
environments, and may be
placed almost anywhere you
wish in the room.

To obtain the most natural
sound you should place the
subwoofer on the oor in the
front half of the room – based
on your favourite listening
position.

Setting the POWER LINK and
LINE switch

Use this switch to set up your
system.

…To a Bang& Olufsen system:

Use a Bang & Olufsen Power Link

cable to connect the subwoofer to
your system. Set the switch to
POWER LINK.

…To a non-Bang& Olufsen

system:

Use a special cable with an
ordinary phono/mini jack plug in
one end, and a DIN-plug in the
other (optional accessory, available

from your Bang& Olufsen retailer).

Set the switch to LINE.

Setting the -dB/0dB switch

Use the -dB/0dB switch to adapt
the output from the subwoofer to
the sensitivity levels of the different
connected BeoLab speakers.

Only when using the subwoofer

with BeoLab4 PC, set the switch

to -dB.

Ideally the subwoofer should be
placed at about the same
distance from your favourite
listening position as the front set
of speakers, that is, the left,
(centre) and right speakers.
If possible, you should choose a
placement between the two front
speakers.

For all other speakers, set the
switch to 0dB.

Setting the EXT. and INT. BASS
MANAGEMENT switch

Depending on your setup, you
have to make settings for the bass
management.

– Set the switch to ‘EXT. BASS

MANAGEMENT’ if the
subwoofer is connected to a
subwoofer socket on a product
and no speakers are connected
to the subwoofer.

– Set the switch to ‘INT. BASS

MANAGEMENT’ if other
speakers are connected directly
to the subwoofer.

Setting the POS. switch

Use the position switch to lter out

the natural bass change obtained if
the subwoofer is placed, for example,
in a corner, as compared to a more
freestanding position.

The setting of the POS. switch is
based on the number of surfaces
the subwoofer is in close proximity

of (within approx. 50cm).

The POS. switch has three

settings:

POS.1: Use this setting if the

subwoofer is close to one
surface (freestanding in a room

or on a wall). Shown by light

grey areas in the illustration.

POS.2: Use this setting if the

subwoofer is placed close to two

surfaces (placed on the oor close
to a wall). Shown by medium

grey areas in the illustration.

POS.3: Use this setting if the

subwoofer is placed close to

three surfaces (in a corner).

Shown by the dark grey areas in

the illustration.

The positions mentioned are

guide lines only. You may set the
POS. switch to any of the three
positions depending on your
sound preference.

Set the POS. switch depending
on your setup.
