Intellivox ADC Installation Manual

MODEL H90 ONLY

The location of the acoustic centre of the Model H90 is

in the centre of the unit, both horizontally and vertically.

This is indicated by the yellow sticker on the front grille.

The H90 should be mounted accurately so that

its acoustic centre is at the position identified by the

site survey.

The arrangement of drivers in the H90 differs from the

V90; for this reason, a different set of measurements

needs to be accurately made. For the H90, the critical

aspects of the mounting position are that the horizontal

(long) axis of the enclosure should be precisley

horizontal, and that if the H90 is not being mounted

against a wall (i.e., suspended from a pole or similar

arrangement), the azimuth angle – the angle about the

enclosure's central vertical axis – should also be exactly

that specified by the DDA survey. Further to these

criticalities, the angle of rotation about the horizontal

axis should also be carefully checked to ensure that the

"downwards" radiating angle of the unit is correct.

MOUNTING OPTIONS

Intellivox ADC models have two attachment points at the

rear of the enclosure; the loudspeaker should be mounted

using these points. Each point consists of four M5 threaded

inserts and only the screws supplied with the original

mounting hardware should be used.

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.
