User manual B&W CCM 618

[. . . ] You can call B&W in the UK or visit our web site to get the contact details of your local distributor. To validate your warranty, you will need to produce this warranty booklet completed and stamped by your dealer on the date of purchase. Alternatively, you will need the original sales invoice or other proof of ownership and date of purchase. Placement near a wall/ceiling junction or in a corner may give rise to too much bass and a boomy quality to the sound. [. . . ] 1 channel The horizontal angle to the centre of the listening position should be approximately 120º round from the centre of the screen. 1 channel Position two speakers to the sides in line with the centre of the listening area and one centrally behind the listeners (figure 4) 7. 1 channel Position two speakers to the sides in line with the centre of the listening area and two behind the listeners, subtending an angle of approximately 40º. This pack should contain: 2x 2x 2x 2x Frame/baffle with drivers and crossover Grille Paint mask Mounting template Check that there is no conflict with other installations (pipe work, air conditioning, power cabling etc. In existing drywall construction, use a stud-finding tool to map the construction accurately and a pipe detector to scan the proposed installation position. Ensure that there is enough clearance behind the plasterboard (sheetrock) for the clamps to swing out fully. avoid installing the speakers in the same cavity 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 10 litres (0. To maintain clarity and speech intelligibility, it's important that listeners are never too far off axis of the nearest speaker. The speaker spacing will depend on the height of the ceiling and the level of sound required. We recommend that the distance between adjacent speakers is no more then 3 times the distance between average ear height and the ceiling. For any given spacing, there will be fewer weak spots with a triangular grid than a rectangular one. 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 10 to calculate the minimum gauge of cable required. This, in conjunction with rotating the whole speaker, allows you to optimise the sound dispersion in relation to the listening area. (figure 8) Direct the tweeter towards the listening area to improve high frequency definition and imaging if the speaker has to be mounted too far off line. Conversely, in surround applications, it may be desirable to point the tweeter away from the listening area to create a more diffuse sound field. The switch on the front baffle provides boost or cut to the speaker's highfrequency output level to compensate for listeners positioned severely off axis or a dull acoustic (boost) or highly reflective rooms (cut). Trace round the outer edge of the template and cut neatly just inside the line. [. . . ] With the grille removed, position the speaker in the aperture and screw in the 4 screws visible from the front. These screws automatically swing out clamping dogs that locate behind the mounting surface. Ensure that they have located properly before fully tightening the screws. A certain amount of flexing of the frame is allowed to take up unevenness in the mounting surface, but do not overtighten f. [. . . ]
