User manual B&W CDM CNT

[. . . ] Although many of these have been developed initially for the more expensive models, our "waterfall" design policy has seen them incorporated, wherever possible, elsewhere in the product range. Features to be found in the CDMTMNT Series include cabinets with contoured edges to reduce sound diffraction (the radiation of sound waves from sharp edges that interfere with and blur the direct sound from the drive units). an integral part of the CDMTM range is the use of Kevlar® cone bass/midrange drive units for lowest coloration and maximum definition. [. . . ] Because of the higher stray magnetic field in front of the speakers, we recommend you keep magnetically sensitive articles (computer discs, audio and video tapes, swipe cards and the like) at least 0. Consult your decoder manual for further information on how to set the levels. The performance of the speaker will change subtly during the initial listening period. If the speaker has been stored in a cold environment, the damping compounds and suspension materials of the drive units will take some time to recover their correct mechanical properties. The drive unit suspensions will also loosen up during the first hours of use. The time taken for the speaker to achieve its intended performance will vary depending on previous storage conditions and how it is used. As a guide, allow up to a week for the temperature effects to stabilise and 15 hours of average use for the mechanical parts to attain their intended design characteristics. If you wish to use an aerosol cleaner, remove the grille first buy gently pulling it away from the cabinet. Spray onto the cleaning cloth, not directly onto the cabinet. The grille fabric may be cleaned with a normal clothes brush whilst the grille is detached from the cabinet. Avoid touching the drive units, especially the tweeter, as damage may result. (Figures 2 & 3) All connections should be made with the equipment switched off. There are 2 pairs of terminals at the back of the speaker which permit bi-wiring if desired. On delivery, the separate pairs are connected together with high-quality links for use with a single 2-core cable. For single cable connection, leave the links in place and use either pair of terminals on the speaker. 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. Incorrect connection can result in poor imaging and loss of bass. To bi-wire, remove the links by loosening the terminal caps and use a separate 2-core cable from the amplifier to each pair of terminals. [. . . ] Adjust the levels of the three front speakers to get a smooth transition of sounds as they pan across the screen. Adjust the level of the surround speakers so that, except for special effects, your attention is not unduly attracted to them. Sit in all likely listening positions when deciding on the optimum levels. [. . . ]
