PREPARING FOR INSTALLATION
Before starting to install the Intellivox 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 proprietary simulation and optimisation
software for these products*). This procedure will have
identified the optimum physical location for the Intellivox,
to accurately achieve the desired acoustic coverage. In
particular, the “acoustic centre” position will have been
specified, in terms of height above the finished floor. The
installer
should
confirm
that
he/she
has
this information.
• Unless specified otherwise by the sound system
designer, the Intellivox column 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 all mounting positions (2 or 3 depending
on model) are in the same plane.
• The Intellivox is configured to operate from either
230 V or 115 V AC mains. A suitable AC mains outlet should
be provided adjacent to the loudspeaker’s intended mounting
position, taking the position of the electronics module into
account. The outlet must be on a circuit able to handle the
full-load power consumption as well as supply the maximum
in-rush current drawn by the electronics module; these figures
vary with model, and can be found in the datasheet supplied
with the unit. The third terminal of the mains outlet must be
connected to a proper safety ground. Local safety regulations
may require a separate mains distribution network or an
uninterruptible mains power supply (UPS).
SIGNAL AND CONTROL CABLES
• In addition to the mains supply, some or all of the following
cables (shown in fig 4) will need to be run to the loudspeaker
position. The necessity for each of these will have been
determined by the system designer; the installer should ensure
that he/she has these details to hand. Depending on the specific
access issues, it may be better to ensure that these cables are
in place and correctly terminated “ready-to-plug-in” before the
Intellivox is mounted in position. All wiring details can be found
on pages 9-15.
• Audio inputs: the Intellivox accepts line level audio
(0 dBV). Two separate transformer-balanced audio inputs
are provided; however, units are shipped with only input 1
active. Input 2 can be made active via WinControl.
Alternative input sections are available separately:
accepting either one line level input and one 70 V/100 V
input or two 70 V/100 V inputs. This option needs to be
specified at the time of ordering.
• Network connection: all Intellivox products are
configured, and may also be monitored, from a PC running
WinControl software. With all installations it will be
