User manual B&W LCR 60 SERIE 3

[. . . ] As a front centre speaker: 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. As a surround speaker: There are two ways of presenting surround information. You can either attempt to get good imaging in all directions or go for a more diffuse, ambient effect. [. . . ] All Applications The speaker may be used in either vertical or horizontal orientation. 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. NOTE: The badge on the grille can be rotated through 90 degrees to suit the orientation of the speaker. 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 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. If not, switch off the set at the mains for 15 minutes and switch on again. 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. Specification and use a low inductance cable to avoid attenuation of the highest frequencies. If you wish to use an aerosol cleaner, remove the grille first by gently pulling it away from the cabinet. The grille fabric may be cleaned with a normal clothes brush whilst the grille is detached from the cabinet. Avoid touching the drive unit diaphragms, especially the tweeter, as damage may result. The inertness of the support used can affect the sound quality of the speaker. Moving the speakers further from the walls will reduce the general level of bass. Space behind the speakers also helps to create an impression of depth. Conversely, moving the speakers closer to the walls will increase the level of bass. If you want to reduce the bass without moving the speakers further from the wall, fit the foam plugs in the port tubes. (figure 8) 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. [. . . ] (figure 6) 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. 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. When bi-wiring, incorrect connection can also impair the frequency response. The terminals accept 6mm (1/4-in) spades, bared wire ends or round pins up to 6mm diameter and 4mm banana plugs. [. . . ]
