MOUNTING WITH A YOKE ASSEMBLY
Yoke assemblies CDDYA10, CDDYA12 and CDDYA15 may be fitted to Models CDD10, CDD12 and CDD15 respectively, if a yoke
mounting arrangement is preferred. Note that due to the weight of the enclosure, yoke mounting is the only method available
for Model CDD15.
The yoke design and fitting method is the same for all three models; the yoke assemblies differ only in size.
The assembly comes in three parts – the yoke itself, and two side bars which are bolted to the enclosure ends. If the yoke
assembly is being fitted to a wall or ceiling as a permanent installation, first and second fix procedures may be adopted as
described below. If the cabinet is to be hung in horizontal orientation from a pole with a scaf clamp, the yoke assembly can be
fitted to the cabinet in a single operation.
Installation:
Yokes may either be permanently fixed to a wall or ceiling or fitted with a clamp for suspension from a scaffold pole or truss.
Yokes are designed for use in either landscape or portrait orientation.
For permanent installations, a first fix/second fix method may be adopted; here the yoke loop and side arms are fixed in position
and the cabinet mated to the loop at a later date.
When suspending the cabinet from a scaffold pole, the whole yoke assembly should be fitted to the cabinet and the cabinet hung
as a single exercise. In this case, the "First fix" section of the Installation instructions below may be ignored.
The components of the yoke assembly are shown below:
Yokes may be permanently attached to a wall or ceiling. The yoke allows vertical adjustment and if mounted using the single
attachment point in the centre of the yoke horizontal adjustment could also be possible.
The first stage is to fit the side arms to the yoke using the M12 Nyloc nuts supplied. A washer should go between the side arm
and yoke and between the yoke and nut. There are three fixing holes into which the side arms may be fitted, which of these you
use will depend on the angle of down-tilt required, it may be prudent to loosely fit the assembly together at ground level to
determine which will be the best pair of holes to use. Tighten the side arms sufficiently to just allow a little movement for final
positioning. The Yoke assembly should be fitted to the wall or ceiling in its intended position. Four 8.5 mm holes are provided
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 central 13mm hole can also be used to mount the yoke which will
provide horizontal adjustment as well as vertical; however, a sufficiently robust fixing method must be used if attaching from
this single point and we would strongly recommend the use of a secondary safety fitting (see note in "Second fix" below). If not
used for fixing, the central hole may be used for cable access. It is also good practice to terminate the speaker cables with the
Phoenix connectors at this stage.
