User manual B&W CWM CINEMA

[. . . ] The speaker may be mounted in either portrait or landscape orientation. If portrait orientation is used, orient the baffle so that the tweeters are towards the centre of the room. Tilt Axis Control Generally speakers are balanced to have a flat frequency response when listening on axis. As the listening position moves further off this axis changes in this flat response occur. [. . . ] Use the Tilt Axis switch described above for each speaker to direct the sound either left or right towards the listening position. For Home Theatre Installations, the speakers should not be closer together than the width of the screen and their height should be approximately at centre screen height. Home Theatre Centre Channel Applications (figure 3) Theoretically, the best position for a centre channel speaker is behind the centre of the screen, but this can only be realised when using an acoustically transparent projection screen. In most cases the speaker will be positioned in a laterally central position either directly above or directly below the screen. All other things being equal, choose the position that is nearest ear height. Use the Tilt Axis switch described above to direct the sound either up or down towards the listening position. Home Theatre Surround Speaker Applications The sound from surround speakers should be as diffuse as possible. 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. 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). 1x Wall frame with swing out dogs · 1x Accessory pack containing: 4x Self-Tapping screws (for frame to PMK fixing) Not for CWMTM500 4x Machine screws (fixing baffles to wall frames) We suggest you retain the packaging for future use. Remove the grille and baffle from the wall frame 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 4) Fit the separately available pre-mount kit ­ (PMKTM800) 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 slots 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. [. . . ] Failure to observe correct polarity will result in ill-defined panning of sounds and strange phase effects. When choosing cable, keep the total electrical impedance (out and back) below the maximum recommended in the specification. Ask your dealer for advice, as the optimum cable will depend on the length required. Cut off excess length and tie down loose cable to prevent rattles. [. . . ]
