User manual B&W SIGNATURE 7NT

[. . . ] Wherever possible, however, portrait orientation, with the drive units mounted one above the other, is to be preferred as it gives better horizontal dispersion and a more stable stereo image. If landscape orientation is used, orient the baffle so that the tweeters are towards the centre of the room. Do not mix portrait and landscape at left and right, as an imprecise stereo image will be created. The following sections give guidance on optimum positioning, but this may be modified in line with domestic constraints. [. . . ] This ensures that the frontal audio image is not distorted by changes of listener position or head movements. The speakers should generally be placed behind and 0. Ceiling mounting often gives good results in this application. The orientation is less important in this application than in other cases. WARNING: The SignatureTM7NT speakers produce a static magnetic field that extends outside the speakers boundary. As such They should not be placed within 0. 5m (20in) of equipment that may be affected by such a field, e. In addition, loosely fill the whole section of the wall cavity with wadding. Fibreglass and mineral wool matting supplied for heat insulation are suitable, but not closed cell foam or expanded polystyrene. Check that there is no debris that may fall into the speaker (especially in ceiling mount situations). 2 x Wall frame with swing out dogs · 1 x Accessory pack containing: 8 x Self-Tapping screws (for frame to PMK fixing) 8 x Machine screws (fixing baffles to wall frames) We suggest you retain the packaging for future use. Remove the grilles and baffles from the wall frames and, to avoid damage, keep them in their plastic bags (and preferably in the carton) away from the work area until you are ready to fit them. New Construction (figure 3) Fit the separately available pre-mount kit PMK800 for the SignatureTM7NT to the studding before the drywall panels are fitted, following the instructions supplied with the kit. the drywall panels should be fitted up to the pre-mount frame and plastered over. Screw, but do not tighten, 4 of the screws provided through the holes in the wall frame into the pilot holes in the pre-mount frame. Mark along the inside edges of the slots and cut out the aperture neatly. Position the frame in the wall and screw in the 6 screws visible from the front of the frame. These screws swing out clamping dogs that locate behind the drywall. Check that there is no conflict with other in-wall installations (pipe work, air conditioning, powercabling etc. In existing construction, use a stud-finding tool to map the wall construction accurately and a pipe detector to scan the proposed installation position. Avoid installing the speakers in the same cavity of the wall as flimsy ducting, which may be induced to rattle. The speakers are designed to operate satisfactorily in a wide range of cavity volumes, ideally above 15 litres (0. [. . . ] On delivery, both pairs are connected together by high-quality gold plated copper links for use with a single twin cable. For single cable connection, connect either of the positive terminals on the speaker (marked + and coloured red) to the positive terminal on the power amplifier and negative (-, black) to negative (figure 5). when bi-wiring the speakers , loosen the terminal caps and remove the links. Use a separate twin cable from the amplifier terminals to each pair of speaker terminals (figure 5). [. . . ]
