[. . . ] If the central image is poor, try moving the speakers closer together and adjusting the degree of toe-in. 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. [. . . ] It can be mounted on the stand, bracket or placed on its side. NOTE: The badge on the grille can be rotated through 90 degrees to suit the orientation of the speaker and is held in with a spring. To rotate gently pull the badge away from grille set the orientation and reposition in the grille. Home Theatre As a front centre speaker 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. as a front left and right speaker: Make the height of the centre of the speaker approximately the same as the TV or the centre speaker. 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. In both cases position the speakers to the sides and behind the listeners. For a more diffuse effect, mount the speakers higher and point them along either the rear or side wall. Stand (figures 3 & 4) The stand can be fitted so the speaker can be positioned either horizontally or vertically, using either of the mounting slots on the rear of the speaker. Determine your choice of orientation and then slide the speaker onto the stand. An Allen key is located in the bottom of the stand, remove the Allen Key to tighten the bolt at the rear of the stand once in position to secure the speaker. Return the Allen key to its position in the base of the stand for future use. bracket (figure 5) Using the bracket , mark the four screw positions on the mounting surface carefully. Offer the bracket to the wall, screw in the two screws used for the top two holes, leaving approximately 5mm (0. 2in) of the screw protruding from the wall, screw in the two remaining screws at the bottom of the mounting base, finally tighten the screws. Again the speaker can be fitted so the orientation is either horizontal or vertical, using either of the mounting slots 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. [. . . ] check the settings to obtain the best average result at all probable listen 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. [. . . ]
