[. . . ] Indeed, you may even change the characteristic for different types of programme and, as the total energy into the room is the same in both modes, no recalibration of the installation is necessary when switching between them. In dipole mode, the front tweeter is disconnected; the two side firing drivers are brought into operation and the crossover frequency to the bass unit is lowered. The side units are connected out of phase with one another, which creates a wedge-shaped null zone at right angles to the wall. If the listeners sit within this zone, they become less aware of the location of the speakers and hear more reflected sound; hence the diffuse nature of the sound field. [. . . ] all formats The surround speakers will normally be placed approximately 60cm (2 ft) above ear height. Although the speaker can theoretically be fitted to the ceiling, it is not recommended unless precautions are taken to prevent the speaker sliding off its mounting. B&W cannot accept any responsibility should the speaker fall from a ceiling mount. Surround speakers generally fall into two main types ­ those that one might describe as 'normal' speakers ­ so-called monopoles, where the sound comes from a set of drive units mounted on the front of the enclosure ­ and those that give a more diffuse sound field, such as dipoles. Most multi-channel music is recorded with home entertainment in mind and is monitored using monopole surround speakers, whatever the multi-channel recording format. This enables better location of side and rear images, although the formation of such images is never quite as precise as it is between the front speakers. Most films are originally balanced for cinemas, where a large number of speakers spread around the auditorium are used to create the surround sound field. In that case there are more surround speakers than there are discrete channels of information and a less precise image is created that gives an all-enveloping effect. Dipoles and similar diffuse speakers are better at recreating this type of sound field in the home, but using fewer speakers to do it. Image positioning with these types of speaker is never as precise as it can be with monopoles. However, they do have the 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 The speakers are handed in terms of which side the positive and negative dipole lobes are projected. Indication is via an arrow on the label at the back of the speaker, which points towards the positive lobe. (figure 5) To optimise the smoothness of sounds panning from the front of the room to the back and vice versa when speakers are used in dipole mode, we recommend that the side speakers have their positive lobes (arrows) pointing towards the front of the room and the rear speakers have their positive lobes (arrows) pointing towards the centre of the rear wall. the outside dimensions of the template correspond to the rear of the cabinet. Stick 4 of the clear self-adhesive rubber pads to the rear panel of each speaker, one close to each of the small bumps in the corners. These stop the speaker vibrating against the surface and help keep it in position. (figure 9) Adjust the protrusion of the screws such that the rubber pads are a friction slide on the surface when the wall plates are hooked over the screw heads. (figure 10) Always check and ensure that: · All the screws slide right to the ends of the slots in the wall plates. Screw protrusion is adjusted so that the rubber pads provide enough friction to prevent the speakers sliding out of position. [. . . ] All surround speakers dipole It would be unusual, but not impossible, to set side speakers to monopole and rear speakers to dipole. If you wish to use an aerosol cleaner, remove the grille first by gently pulling it away from the cabinet. With the grille detached from the cabinet, clean the fabric with a normal clothes brush or vacuum cleaner with appropriate accessory. Avoid touching the drive units, especially the tweeter, as damage may result. [. . . ]
