Intellivox ADC Installation Manual
3. INSTALLATION GUIDE
PREPARING FOR INSTALLATION
Before starting to install the Intellivox ADC loudspeaker, a
number of points should be considered.
• It is assumed that the installation site has been the
subject of an extensive DDA investigation or optimisation
prior to the actual install. (DDA = Digital Directivity
®
Analysis, the AXYS
proprietary simulation software for
these products*). This procedure will have identified the
optimum physical location for the Intellivox ADC, to
accurately achieve the desired acoustic coverage. In
particular, the "acoustic centre" position in terms of
height above the finished floor, and any mechanical
mounting angles will have been specified. The installer
should confirm that he/she has this information.
• Unless specified otherwise by the sound system designer,
the Intellivox ADC Model V90 should be installed at a
position exactly perpendicular to the listening plane
(i.e. vertical if the floor is horizontal). Unlike conventional
loudspeaker systems, minor mechanical misalignment
may lead to degraded coverage and intelligibility. Ensure
(by use of a levelling device such as a spirit level) that
the surface to which the Intellivox is to be attached is
absolutely vertical and that both mounting bracket
positions are in the same plane. This restriction does
not apply to the Model H90, which is intended to be
tilted downwards.
*Authorised electro-acoustic consultants or 'build & design' sound contractors can apply for a DDA License free of charge.

INTELLIVOX ADC CONNECTIONS
The Intellivox ADC range loudspeakers are designed to be
connected to 100 V or 70 V line speaker distribution
systems. They are not intended to be used with amplifiers
which are designed to drive only low-impedance (i.e. 4 - 8
ohms) loudspeakers. However, such amplifiers may be used
if intermediate 100 V/70 V line transformers are connected
between the amplifier outputs and the loudspeakers.
Suitable power amplifiers for use with the Intellivox ADC
®
range include the AXYS
PB-400 and PB-800 models.
In most situations, installation will be simplified by running
the speaker cables to the intended location before
attempting to mechanically mount the Intellivox speakers.
If the loudspeaker is being used as part of a Voice Alarm
application, it is likely that fire-resistant (pyro) cable will be
required; local regulations covering these requirements
should always be checked and followed.
The cable entry gland at the rear of the ADC models can
accept cable with a maximum diameter of 13.5 mm. Ensure
that the cable being installed does not exceed this.
Wiring details can be found on page 12.
