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.

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.
