The lightning flash with arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons.

The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

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 loud speakers are in standby, ready to be used.

The loudspeakers are designed to be left in standby mode when not in use.

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

Switching on and off

When you switch on your system, the loudspeakers switch on simultaneously, and the indicator lights turn green. When you switch the system off again the loud speakers also switch to standby.

Cleaning the Unit

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 firmly.
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!

The indicator light is positioned behind the exposed speaker membrane in the acoustic lens.

Unit protection

Each loud speaker is equipped with a thermal protection system which prevents damage from overheating. If an error occurs – or the speaker units become overheated – the system automatically switches the loud speaker 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 loud speaker to the mains supply.

Should the problem persist, contact your Bang & Olufsen retailer.

Set up the Device

We recommend that you follow this procedure when you set up the loud speakers:

• Disconnect your system from the mains supply.
• Connect your loud speakers and set the switch marked LINE–RIGHT–LEFT on each loud speaker as explained in 'Cable connections'.
• Set the switch marked FREE–WALL– CORNER to the correct setting on each loud speaker. This is explained in 'Adapt the loud speakers to your room'.
• Connect your entire system to the mains supply again.

The loud speakers must be placed standing upright on the base on a firm and level surface.

Cautions

• Make sure that the loud speakers 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 loudspeakers to an easily accessible wall socket.
• Do not attempt to open the loud speakers. Leave such operations to qualified service personnel!
• The loud speakers are designed for in door 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 loud speakers enclosed in a small space, and never place anything directly in front of the loud speakers.
• Place the loudspeakers with the front facing your favourite listening position.

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.

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.

Connection panel

FREE–WALL–CORNER switch
This switch has three settings. Which setting to use depends on the placement of the loud speakers. This is explained in 'Adapt the loud speakers to your room'.

LINE–RIGHT–LEFT switch
This switch has three settings. Set the switch to RIGHT or LEFT, when connecting the loud speakers to a Bang &Olufsen system. Set the switch to LINE when connecting the loud speakers 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.

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.

Securing the cables

For safety reasons, the mains lead must be fastened to the loud speaker. 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 loud speaker.

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:

1. Run a Power Link cable from your Bang & Olufsen system directly to each loud speaker.
   
   Or
2. Run a Power Link cable from your Bang & Olufsen system to the first loudspeaker, and then run another Power Link cable to the next loud speaker. This will often help to minimise cable clutter.
   

Adapt the device 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.

How to measure

The distances referred to are measured as shown here (the loudspeaker seen from above).

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 loud speaker 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 loud speaker. The appropriate switch setting depends on the distance from the loud speaker 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.

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.

If you have a BeoLab 2 subwoofer setup
As explained in the BeoLab 2 Guide, the sub woofer has a setup switch which can be set to 1, 2 or 3. The settings of this switch will adapt the output from BeoLab 2 to the sensitivity levels of different loud speakers.
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.

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 loud speakers.

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.

Example 3: As in example 2, one loud speaker 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 loud speaker should be set to WALL, and the right loudspeaker should be set to CORNER.
