Limited Warranty

Dear customer,

Welcome to B&W.

This product has been designed and manufactured to the highest quality standards. However, if something does go wrong with this product, B&W Loudspeakers and its national distributors warrant free of charge labour (exclusion may apply) and replacement parts in any country served by an official B&W distributor.

This limited warranty is valid for a period of five years from the date of purchase or two years for electronics including amplified loudspeakers.

Terms and Conditions

1The warranty is limited to the repair of the equipment. Neither transportation, nor any other costs, nor any risk for removal, transportation and installation of products is covered by this warranty.

2This warranty is only valid for the original owner. It is not transferable.

3This warranty will not be applicable in cases other than defects in materials and/or workmanship at the time of purchase and will not be applicable:

a.for damages caused by incorrect installation, connection or packing,

b.for damages caused by any use other than correct use described in the user manual, negligence, modifications, or use of parts that are not made or authorised by B&W,

c.for damages caused by faulty or unsuitable ancillary equipment,

d.for damages caused by accidents, lightning, water, fire heat, war, public disturbances or any other cause beyond the reasonable control of B&W and its appointed distributors,

e.for products whose serial number has been altered, deleted, removed or made illegible,

f.if repairs or modifications have been executed by an unauthorised person.

4This guarantee complements any national/regional law obligations of dealers or national distributors and does not affect your statutory rights as a customer.

How to claim repairs under warranty

Should service be required, please follow the following procedure:

1If the equipment is being used in the country of purchase, you should contact the B&W authorised dealer from whom the equipment was purchased.

2If the equipment is being used outside the country of purchase, you should contact B&W national distributor in the country of residence who will advise

where the equipment can be serviced. You can call B&W in the UK or visit our web site to get the contact details of your local distributor.

To validate your warranty, you will need to produce this warranty booklet completed and stamped by your dealer on the date of purchase. Alternatively, you will need the original sales invoice or other proof of ownership and date of purchase.

Owner’s manual

Introduction

Thank you for choosing B&W.

Please read this manual fully before unpacking and installing the product. It will help you to optimise its performance.

B&W maintains a network of dedicated distributors in over 60 countries who will be able to help you should you have any problems your dealer cannot resolve.

Unpacking (Figure 1)

Fold the top carton flaps right back and invert the carton and contents.

Lift the carton clear of the contents.

Remove the inner packing from the product.

We suggest you retain the packing for future use.

Check in the carton for:

4 self-adhesive rubber pads

1 Foam bung

1 International warranty booklet

Positioning

If using a projection television with an acoustically transparent screen, place the speaker behind the centre of the screen. Otherwise position it directly above or below the screen, whichever is closest to ear level. Align the front of the speaker approximately level with the screen.

Fix the 4 self-adhesive pads to the base of the speaker. They give a degree of vibration isolation. The flat area on top of the television may be smaller than the base of the speaker, so position the feet accordingly.

Stray Magnetic Fields

The speaker drive units are magnetically shielded such that the stray magnetic field outside the boundaries of the cabinet, except the front, is too low to cause distortion of the television picture in the vast majority of cases.

There are, however, some extremely sensitive televisions – some that even have to be adjusted according to their alignment with the earth’s magnetic field. If you have a problem, first degauss the television set with the speaker in place. Some have a button especially for this purpose. If not, switch off the set at the mains for

15 minutes and switch on again. Merely

putting the set into standby mode is not sufficient.

If you still have a problem, try moving the speaker either forwards or backwards a little to get a more favourable juxtaposition, or space the speaker further from the television until the distortion disappears.

Because of the higher stray magnetic field in front of the speakers, we recommend you keep magnetically sensitive articles (computer discs, audio and video tapes, swipe cards and the like) at least 0.2m from the speaker.

Connections (Figures 2 & 3)

All connections should be made with the equipment switched off.

There are 2 pairs of terminals at the back of the speaker which permit bi-wiring if desired. On delivery, the separate pairs are connected together with high-quality links for use with a single 2-core cable. For single cable connection, leave the links in place and use either pair of terminals on the speaker.

Ensure the positive terminal on the speaker (marked + and coloured red) is connected to the positive output terminal of the amplifier and negative (marked – and coloured black) to negative. Incorrect connection can result in poor imaging and loss of bass.

To bi-wire, remove the links by loosening the terminal caps and use a separate

2-core cable from the amplifier to each pair of terminals. This can improve the resolution of low-frequency detail. Observe the correct polarity as before. When bi-wiring, incorrect connection can also impair the frequency response.

Ask your dealer for advice when choosing cable. Keep the total impedance below the maximum recommended in specification and use a low inductance cable to avoid attenuation of the highest frequencies.

Fine tuning

For greatest realism in home theatre installations it is important to balance the speakers and adjust the acoustic image to match the size of the screen. With smaller screens it may be more realistic to have the left and right speakers closer together than you might for audio alone.

Adjust the levels of the three front speakers to get a smooth transition of sounds as they pan across the screen. Adjust the level of the surround speakers so that, except for special effects, your attention is not unduly attracted to them.

Sit in all likely listening positions when deciding on the optimum levels.

If you want to reduce the bass level without moving the speaker further from the wall, fit the foam bung in the port tube. (Figure 4)

Consult your decoder manual for further information on how to set the levels.
