User manual B&W LCR3

[. . . ] The speaker is primarily intended for home theatre installations, but is equally at home with 2-channel audio. Separate sections in the manual are devoted to the two applications. 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. As a surround speaker: There are two ways of presenting surround information. [. . . ] However, vertical orientation offers better horizontal dispersion and is to be preferred in most cases as this leads to a more stable image over a wide listening area. Horizontal orientation can be used with little detriment to the imaging if the speaker is used in the front centre position of a home theatre installation where the listeners are within 15° of the centre line ­ equivalent to 0. Leave at least 10cm clear space between the back of the speaker and the wall behind, to allow the port to operate properly. fix the 4 self-adhesive pads to the base of the speaker. They give a degree of vibration isolation, especially useful if placing the speaker directly on top of a fairly flimsy television. 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 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 B&W national distributor in the country of residence who will advise 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 speaker, we recommend you keep magnetically sensitive articles (computer discs, audio and video tapes, swipe cards and the like) at least 0. Home Theatre Refer to your decoder manual and set the levels and delay times for all the speakers. check the settings to obtain the best average result at all probable listening positions. Except for special effects, the general level of the surround field should not be too obvious. Adjust the spacing of the front left and right speakers so that the size of the acoustic image matches the size of the screen. Adjust the toe-in of the front left and right speakers to get a smooth transition of sounds that pan from one side to the other. adjust the angle of the surround speakers to give the best results with a variety of material. 2-Channel Audio If the central image is poor, try moving the speakers closer together and adjusting the degree of toe-in. All connections should be made with the equipment switched off. [. . . ] If the bass is uneven with frequency it is usually due to the excitation of resonance modes in the room. Even small changes in the position of the speakers or the listeners can have a profound effect on how these resonances affect the sound. Try mounting the speakers along a different wall. Even moving large pieces of furniture can have an effect. [. . . ]
