3. INSTALLATION GUIDE
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 JBL proprietary simulation and optimisation software
for these products*). This procedure will have identified the
optimum physical location for the Intellivox loudspeaker,
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 surfaces to
which the Intellivox is to be attached are absolutely vertical
and in the same plane, and that all the individual fixing
holes are themselves in the same plane.
• The Intellivox operates from both 230 V and 115 V AC
mains supplies; a suitable AC mains outlet will be required
at the loudspeaker location. The outlet must be on a circuit
able to supply the maximum short-term in-rush current
drawn by the amplifier. Refer to the datasheet supplied for
the actual figures specific to the model being installed. 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). The mains connection to the
Intellivox should incorporate a manual circuit breaker or an
accessible mains plug.
* Authorised electro-acoustic consultants or 'build & design' sound contractors can apply for a DDA License free of charge.
This license can be obtained through our website at www.jblpro.com.
For further information please refer to the Help files and manual with the DDA software.

• All cables to the Intellivox should pass through glands
or flexible conduit at the rear of the unit. If the particular
installation circumstances permit (i.e., the height of the
installation and availability of spare cable length), it will
usually be easier to perform all electrical connections at
ground level (see "Signal and Control Cables" for full
details).
SIGNAL AND CONTROL CABLES
• In addition to the mains supply, some or all of the
following cables will need to be run to the loudspeaker
position from the rack location. 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 before the Intellivox
is mounted in position. All wiring details can be found at
"Connector and Wiring Details" on page 9.
