The ceiling bracket assembly may now be fixed to the ceiling. There are three 5.5 mm holes and
a central 8.5 mm hole in the bracket for this purpose. It is essential that appropriate fixings are
used to allow safe and secure attachment to the ceiling material, particularly as these may be
fitted overhead public areas. The method of fixing will depend on the ceiling construction. You
can use the larger central 8.5 mm hole as the principal fixing initially: this lets you adjustment
the bracket to obtain the correct horizontal coverage by pivoting it on the single mounting. When
the position is correct, tighten it, and add further fixings to the other three holes to ensure a safe
and secure mounting. Alternatively, if an adequate fix can be obtained using the three smaller
holes alone (e.g., by using wood screws into a batten above plasterboard), it may be possible to
use the 8.5 mm centre hole for cable routing.
In any case, it is good practice to terminate the speaker cables with the Phoenix connectors at
this stage.
Second fix:
With ceiling mounting, the CDD5 will probably be used in landscape mode: fit the cabinet
section of the wall bracket using the four "upper" screws as shown below:
Note that is vital that the driver is orientated to suit the deployment used. "Out of the box"
the driver is in the correct position for "portrait" use and must be rotated through 90° for
"landscape" use. Please see page 12 for details of driver rotation.
It is also possible to ceiling mount the CDD5 in portrait mode by using the "lower" four screws
to fix the cabinet section of the wall bracket, but in this case the cabinet should be mounted
upside down, and the driver and grille will both need to be rotated 180°. The sloping bottom of
the cabinet allows a close fit to the ceiling which may be more aesthetically pleasing in some
installations.
