[. . . ] 5m (20in) of equipment that may be affected by such a field (eg Cathode Ray Tubes in TVs and Personal Computers). Since its foundation in 1966, the continuing philosophy of B&W has been the quest for perfect sound reproduction. Inspired by the company's founder, the late John Bowers, this quest has entailed not only high investment in audio technology and innovation but also an abiding appreciation of music and movies to ensure that the technology is put to maximum effect. [. . . ] 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 Always try to keep the resistance as low as possible with the loop resistance preferably below 0. Use the table of figure 11 to calculate the minimum gauge of cable required. The template is marked with both vertical and horizontal centre lines to aid alignment. Trace round the outer edge of the template and cut neatly just inside the line. To improve the mechanical integrity of the wall and reduce the likelihood of rattles, we recommend you apply a bead of wood glue or mastic along the joints between the back of the plasterboard and the studs in the vicinity if the speaker. Run the cable to the aperture, allowing enough length to comfortably connect the speaker, but not too much, as the excess may rattle against the structure. Plastering to avoid rattles as a result of the plaster shrinking away from the back box as it dries. If using plasterboard, stick the sheets to the surfaces of the back box using flexible mastic. Depending on the diameter of the router, you may need to square off the corners with a saw. In all cases, we recommend not using cement or mortar to fix the back box into the brick or blockwork. Fill the wall cavity or back box, but not the space immediately behind the speaker, with unlined fibreglass or mineral wool matting. The packing density should be just enough to comfortably prevent the material from dropping or sagging over time. In an open wall cavity, fill to a distance of at least 30cm (1 ft) above and below the speaker. (figure 8) IMPORTANT: Ensure that the materials you use meet local fire and safety regulations. The speaker can be installed once the wall is completed in the same manner as retrofitting, but it is easier to position and cut the hole if the optional pre-mount kit is used before the plasterboard (sheetrock) is fitted. [. . . ] It is possible to provide this cavity simply by using a lintel, covering the hole with plasterboard and fitting the speaker as described above for retrofitting into a drywall. (figure 6) However, the back box provides a useful means of defining the minimum volume required. Follow the instructions with the back box for fitting and running the cable. [. . . ]
