Daily use When you have finished setting up the loudspeaker as described on the following pages, connect the entire system to the mains. Loudspeaker protection The 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 automatically switches the loudspeaker to standby. To restore the sound: > Disconnect the loudspeaker from the mains.
Set up the loudspeaker 4 We recommend that you follow this procedure: – Disconnect your Bang & Olufsen system from the mains. – Mount the loudspeaker to the Bang & Olufsen stand or wall bracket as explained on the next page. – Connect the loudspeaker as explained in ‘Cable connections’ (pp. 6–7). – Set the POSITION switch to the correct setting. This is explained in ‘Adapt the loudspeaker to your room’ (pp. 8–9). – Connect the entire system to the mains again.
Here is shown how to fasten the loudspeaker with a ‘type 1 bracket’ to a Bang & Olufsen ‘single-column’ stand (or wall bracket). Use the same procedure if you wish to fasten the loudspeaker to a Bang & Olufsen ‘double-column’ Stand – with a ‘type 2 bracket’. a Remove the small cover (if any) on the stand. Press the cover as shown, and it will come loose. b Fasten the bracket to the stand or wall bracket. Use the two longest screws (M5 × 25 mm) – four screws for a ‘type 2 bracket’.
Cable connections 6 The loudspeaker is primarily intended to be used in a surround sound setup with BeoVision 7*. It may, however, be used with other Bang & Olufsen systems as well – for example in a BeoVision 4 surround sound setup. Mains connection to BeoVision 7 POWER LINK socket POSITION switch If used in a setup not including BeoVision 7, you will require a mains cord and a Power Link cable. These cables are available as optional accessories from your Bang & Olufsen retailer.
Connection to BeoVision 7 … Connect the loudspeaker to one of the Power Link sockets on the left BeoVision 7 socket panel. BeoVision 7 BeoLab 7-4 For further information about the BeoVision 7 socket panels, refer to the Guides enclosed with the product. Cable clamp: For safety reasons, the mains cord from the wall outlet must be secured to the loudspeaker. To do so, tug the cord behind the clamp. The two mains cords and the Power Link cable are enclosed with BeoVision 7.
Adapt the loudspeaker to your room 8 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, use the POSITION switch 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.
The POSITION switch is located on the loudspeaker socket panel. F W How to measure: The distance is measured as shown here – the loudspeaker seen from above.
To get access to the approval labels, remove the loudspeaker front grill: Push the front grill downwards until stop (~ 10 cm/4"). The front grill can now be removed. Note: When attaching the front grill again, first insert the centre peg into the bottom end of the groove (a), and move the front grill upwards. Make sure that all six ‘attach-points’ engage fully with the corresponding brackets on the loudspeaker (b), so that the front grill is properly seated.
