MODEL V90 ONLY
Model V90 only: There are three options for mounting
the Intellivox ADC Model V90:
1. The first (and most often used) method is to use the
standard mounting brackets supplied with the unit.
Dimensions of the bracket are shown in fig.5.1.
The standard brackets allow mounting of the Intellivox
ADC Model V90 on a straight wall or on a curved surface
(e.g., a pillar) with a gap of 25 mm (1.0”) between the
rear of the enclosure and the wall.
The mounting procedure is given on page 13 under
“Mounting Procedure”.
2. A second method is to mount the Model V90 using
(optional) swivel brackets which allow the plane of the
column’s vertical radiating axis to be at an angle other
than 90 degrees to the wall. In this case two swivel
brackets are needed. The horizontal angle of the swivel
brackets can be secured by the hexagonal nut. The
swivel brackets are mounted to the rear of the enclosure
by the four M5 pan head screws instead of the standard
brackets. Two versions of swivel brackets are available,
permitting the Intellivox to be rotated through 45 or 90
degrees either way respectively. Refer to page 17 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. Because of the proximity of the unit to
the walls, particular attention should be paid to the
avoidance of acoustic resonances (see page 11).
MODEL H90 ONLY
Model H90 only: Unlike the V90, considerable flexibility
exists in the mounting possibilities of the H90. The H90
is not specifically designed to be mounted on a vertical
(or angled) wall. The method of mounting employed
in a particular installation will be primarily dictated by
the downwards angle at which the H90 needs to be
mounted to achieve the coverage calculated during the
DDA analysis.
Custom mounting hardware may be required to achieve
the correct mounting angle. Small mounting angles
may be realised using the standard mounting brackets
(supplied) in conjunction with suitable spacers.
The standard mounting brackets supplied with the unit
may be employed if the Model H90 is to be fixed “flat”
onto a vertical wall.
Note that the provided locking mechanism of the
optional hinges and swivel brackets is not suitable for
the standard (horizontal) mounting method.
