User manual B&W CDS3

[. . . ] 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 B&W products are designed to comply with international directives on the Restriction of Hazardous Substances (RoHS) in electrical and electronic equipment and the disposal of Waste Electrical and Electronic Equipment (WEEE). These symbols indicate compliance and that the products must be appropriately recycled or processed in accordance with these directives. Lift the carton clear of the contents and remove the inner packaging from the speakers. [. . . ] 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 allenveloping 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. 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 speaker drive units create stray magnetic fields that extend beyond the boundaries of the cabinet. We recommend you keep magnetically sensitive articles (television and computer screens, computer discs, audio and video tapes, swipe cards and the like) at least 0. The initial turn of the screw will cause the clamps to swing out into position and further turning will draw them towards the back of the wall. In retrofit situations without the PMK for protection, take care not to over tighten the clamps, otherwise the plasterboard will crush and weaken the fixing. (figure 11) Decorating is best carried out at this stage, before the baffle and drivers are fitted. Never paint over the grille fabric as this will clog the pores and impair the sound. The combination of a black grille frame in front of a black baffle ensures that the cross pattern of the grille frame is least visible, even with white cloth. Connect the cable to the speaker as described in the "Connections" section above and screw the baffle into the wall frame using the pan head screws provided. The grilles are a push fit onto the baffle, but before fitting them, balance the installation following the processor instructions and select dipole or monopole mode as preferred (see below). ensure the positive terminal on the speaker (marked + and coloured red) is connected to the positive output terminal of the amplifier and negative (marked ­ and coloured black) to negative. Use the switch on the front baffle to select between monopole and dipole modes. Retrofit Use a stud finding tool to locate the position of the studs behind the plasterboard panels. The outside edge of the template represents the size of the wall frame. Do not allow the template to overlap a stud position or the swing-out clamps will not operate correctly. (figure 8) New construction When the wall studding is in place, but before the plasterboard (drywall) panels are fitted, fix the premount kit (PMK), following the instructions included with the kit. (figure 9) Plasterboard (drywall) panels may then be fitted with an aperture for the PMK and finished. Make sure that the cable and any other services in the cavity are prevented from rattling against the structure, either by securing or padding. Push acoustic wadding into the wall cavity between the sides of the aperture and the vertical studs and above and below the aperture to a distance of 15cm (6 in) or more.

This guarantee complements any national/regional law obligations of dealers or national distributors and does not affect your statutory rights as a customer. 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 advise where the equipment can be serviced.
