2. A second method is to mount the Intellivox column
using a pair of (optional) hinge brackets, which allow
the plane of the column’s vertical radiating axis to be at
an angle other than 90 degrees to the wall. The hinge
brackets permit the Intellivox to be rotated through
90 degrees, the direction of rotation being determined
by their orientation. Refer to page 23 for ordering
information.
Fig.18 Direction of rotation when using hinge brackets.
3. The third method is to mount the column within a recess
in the wall or dedicated mounting panel so that the
front of the unit is flush. This is a specialised mounting
situation which will be encountered only rarely. Access
to the rear of the unit will still be required for the cables.
Depending on the particular circumstances, it may be
appropriate to remove the mounting brackets from the
rear of the unit.
Because of the proximity of the unit to the walls,
particular attention should be paid to the avoidance of
acoustic resonances (see below).
Cavity walls can sometimes be problematical when high-
power loudspeakers are mounted on them. The internal
wall cavity may resonate at one or more frequencies,
degrading the audio performance significantly. Installers
are advised to insert rockwool or similar sound-absorbing
material into the cavity in the vicinity of the loudspeaker
when mounting an Intellivox on a wall of this type.

of the optional hinge brackets, may be downloaded from

MOUNTING PROCEDURE
The general mounting procedure using the standard
brackets is described below. Please note that once the
Intellivox is mounted, the connector bay can no longer be
accessed.
A M10 lifting point is provided on the top of the unit for
use during installation/maintenance.
This point should NOT be used for permanent
installation. It is only intended as a lifting
point to be used during installation/
maintenance.
The threaded bush on the M10 lifting point
has an internal length of 20 mm. Care should
be taken not to insert a longer thread into this
lifting point as it could compromise the
integrity of the lifting point and/or loudspeaker chassis.
