[. . . ] Founded in 1966, B&W has always striven for perfect sound reproduction in its products. To this end, the company has invested heavily in research and development in order to maintain its position at the forefront of acoustic design. Through the years, B&W has introduced many advanced features and techniques. [. . . ] Lift the carton clear of the contents and remove the inner packaging from the speakers. 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. The terminals accept 6mm (1/4-in) spades, bared wire ends or round pins up to 6mm diameter and 4mm banana plugs. Should service be required, please follow the following procedure: 1 If the equipment is being used in the country of purchase, you should contact the B&W authorised dealer from whom the equipment was purchased. If the equipment is being used outside the country of purchase, you should contact the B&W national distributor in the country of residence who will Surround field will depend to a great extent on domestic constraints ­ how free you are to position the speakers in an ideal position and how large an audience you want to cater for, relative to the size of the room. There is no industry standard for the angle subtended by the surround speakers at the listening position, but most recordings are made with the surround speakers positioned between 110° and 130° from front centre. Place the speakers against the wall within this range of angles, initially on a temporary support that raises the tweeters approximately to ear height. This will define whether you position the speakers on the side or rear wall. If you listen in highbacked chairs, or if the speakers are otherwise obscured, it may be advantageous to raise them higher. Satisfactory results can be obtained with them up to approximately 60cm (2 feet) above ear height. With all speakers positioned for initial listening tests, listen to a wide variety of programme material ­ 5. 1 channel audio, action and small scale movies ­ and sit in all likely listening positions. pay particular attention to the surround information and the stability of the images. If the imaging is unsatisfactory, for example if it becomes too one sided at the extremes of the listening area, or if you cannot place the speakers within the preferred range, you may be better off aiming for a more diffuse sound field. It may also be advantageous to raise the speakers well above ear height. Once you have found the optimum position, fix the speaker permanently in position. [. . . ] If the speaker has been stored in a cold environment, the damping compounds and suspension materials of the drive units will take some time to recover their correct mechanical properties. The drive unit suspensions will also loosen up during the first hours of use. The time taken for the speaker to achieve its intended performance will vary depending on previous storage conditions and how it is used. [. . . ]
