JBL Intellivox Installation Manual
2.INTRODUCTION
This manual describes the recommended installation
procedure for the JBL Intellivox DS / DSX range of loud-
speakers.
The JBL Intellivox is a type of loudspeaker known as an
active DSP-controlled loudspeaker array, which utilises
the principle of multiple, individually-driven loudspeaker
drive units in the vertical plane at specific spacings. In ad-
dition to the drive units, the Intellivox housing contains a
mains-powered electronics module containing multiple
power amplifier channels and a Digital Signal Processing
(DSP) section.
This manual describes the following aspects of an
installation:
• Necessary cabling
• Connector wiring
• Mechanical installation
After installation, the loudspeaker should be tested for
basic functionality using JBL WinControl software; the
manual also describes this procedure. (Note that full
configuration and control of the loudspeaker is beyond
the scope of this manual; this topic is fully documented in
the WinControl Help files.)
Please note that a full range of optional
mounting brackets and connection coverboxes
are available. Please refer to product data-
sheets for further details.
* Models with the HD suffix offer increased directivity
control for high frequencies.
†The DS115 model is an exception, also employing two
different driver types.
202007/IvxIM_v2.3
APPLICABLE MODELS, AND VARIANTS
The various models in the Intellivox range are fitted with
different numbers of drive units.
This manual applies to the following JBL
Intellivox models:
Intellivox-DS115 (fig.1a)
Intellivox-DS180 and DSX180 (fig.1b)
Intellivox-DS280, DSX280 and DSX280HD* (fig.1c)
Intellivox-DS380 and DSX380 (fig.1d)
Intellivox-DS430 and DSX430 (fig.1e)
Intellivox-DS500 and DSX500 (fig.1f)
The DSX models use two different types of drive units in
each loudspeaker instead of the DS’s single type†. These
model differences may be ignored for the purposes of
installation and commissioning.

A standard option applicable to all models is the position
within the housing of the electronics module, which may
either be at the top or bottom of the housing. The position
is relevant to the installation procedure as the “acoustic
centre” (see fig 2) of the loudspeaker array will be different
in the two cases. It is not possible for the electronics
module’s position to be changed after production.

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 sub-
ject 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 fol-
lowing 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 cor-
rectly 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
fig.4 - Intellivox Connections
(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 con-
figured, and may also be monitored, from a PC running
WinControl software. With all installations it will be
*Authorised electro-acoustic consultants or ‘build & design’ sound contractors can download the DDA software from our

necessary to upload the correct settings for each unit to
obtain the desired acoustic coverage. Once this has been
done, there is no longer an operational need to have the
Intellivox connected to a PC because all settings are stored
locally within the unit’s memory and in the event of a pow-
er failure, will be automatically reloaded on power-up. The
system designer will have determined whether a perma-
nent network connection needs to be provided. This will be
the case if the Intellivox is to be monitored remotely during
normal operation. Otherwise, the network wiring can be
omitted, but consideration should still be given to the unit’s
location with regard to ease of both initial and future
access for a PC connection. It may be appropriate to install
network wiring in order to provide a network access point
at a location more easily accessible than the rear of the
Intellivox unit itself. A cable with two individually foil-
screened twisted pairs should be used. Details of suitable
cables can be found on page 24.
• Fault monitoring: if network monitoring is not to be used,
a simple surveillance function may be realised by means of
the Intellivox’s ‘failure detect’ volt-free relay. This connec-
tion requires a 2-core cable.
• Additional cooling: if the ambient temperature is
expected to exceed 40 °C an external fan should be
installed. This may be activated automatically via the
Intellivox’s temperature-controlled fan output; 2-core cable
will be required. The fan should be mounted in a position
which ensures sufficient airflow around the heatsink.
• Ambient Noise Sensing: the Intellivox is equipped with a
built-in microphone to provide a signal for its embedded
autogain algorithm.

CONNECTOR AND WIRING DETAILS
All connections to the Intellivox (except mains power) are
made via the connector block at one end of the electronics
module. The IEC mains socket is immediately adjacent to
the connector block.

fig.5.2 - Additional access to connector block via
the front cover plate
Additional access to the connectors is available via the
connector plate located between the amplifier and
loudspeaker baffle. Removal of the front grille will be
necessary to gain access.
AC MAINS
The Intellivox is equipped with a 3-pin IEC
mains connector with an integral fuse holder.
Only ever replace the fuse with one of the same type and
rating. Never attempt to replace a fuse without first
removing the IEC plug from the unit. Be sure that the mains
voltage stated on the unit complies with the local standard
before connecting the Intellivox to the mains supply. Be
sure to use the appropriate cable diameter for the
power consumption of your particular Intellivox model.
202007/IvxIM_v2.3
A pre-made IEC mains cable (with the appropriate plug
for the territory) may be used if one of a suitable length is
available. Otherwise, use the mating IEC cable socket
supplied, and wire to the intended mains outlet. Note that
this connector is only suitable for use with stranded
“appliance” cable, not rigid mains installation cable.
Warning – This apparatus is a Class I device and
must be connected to a mains socket outlet
that provides a safety ground connection.

WAGO CONNECTORS
All other Intellivox connections are made via the four on-
board WAGO Type 231 multi-pin connectors. These are:
• Audio (6-way male)
• Network (5-way male)
• Ambient noise mic/Ext. temp. sensor (5-way female)
• Failure detection/Fan control (5-way female)
One 5-way and one 6-way mating female connec-
tor is supplied with every unit for the network and
audio connections. 5-way mating male connectors for
the other two sockets are available separately from JBL if
required (see page 22), but will be shipped with the unit
if specified at the time of order.
To wire the WAGO Type 231 connectors, proceed as
follows:
1) Prepare the cable; strip back approximately 8-9
mm (0.35”) of the insulation of each core.
2) Refer to the table below: select the appropriate PVC in-
sert for the wire size. If the wire is too big for the largest
size insert, the inserts can be ignored and the wire
connected directly (next step). Insert the wire into the
insert so that the bare end goes through the hole
but the insulated portion does not.
JBL Intellivox Installation Manual
3) Using the wire insertion tool supplied as shown below,
open the clamp contact in the connector shell by pressing
inwards towards the shell.
fig.7.2 - Using the WAGO insertion tool
4) Insert the stripped wire, with or without a PVC insert,
into the hole as shown. If using an insert, ensure that it is
fully seated. Release the wire insertion tool, and check that
the wire is secured. Repeat from Step 2 for all other cores.

AUDIO INPUTS
The Intellivox is normally supplied with two transform-
er-balanced line inputs. Selection of Input 1 or Input 2 as
audio source is made from the WinControl software
via the network, and for most installations only Input 1
need be wired. However, Input 2 may be connected to a
secondary signal path (in case of a failure elsewhere in
the system), or to an emergency sound source.
For optimum results only use good quality balanced audio
cable consisting of a twisted pair and an overall screen.
The audio source(s) (e.g. the Octadrive) should have
a low impedance balanced output. The nominal line input
level is 0 dBV.
For applications requiring direct connection to a 70 V/100
V distributed loudspeaker system the Intellivox may be
ordered with an alternative input module having either
one 70 V/100 V audio input and one 0 dBV line level input
or two 70 V/100 V inputs. Refer to Appendix for order
codes.
The audio connector pinout is as follows:
fig.8.1 - Audio input connections
If the source equipment has a well-designed balanced
output and the wiring strategy shown below is used, there
should be no problems with hum or other extraneous noise.
Note that pins 3 and 6 of the audio connector are analogue
audio grounds, they should be used only for connecting the
screen of the audio cables, and for no other purpose.

Due to the complex architecture of some large audio
systems, unexpected hum or noise may occur due to
ground loops, or injected noise from other equipment
elsewhere in the system. If this occurs, please refer to
the Appendix (p24) and to our website, where additional
guidance on grounding strategies will be found, with
general techniques that may be applied in order to reduce
ground-induced noise.
*A simple failure monitoring scheme based on impedance switching can be implemented on this 70 V/100 V input.

NETWORK CONNECTION
The RS-485 network connection should be permanently
wired in any of the following situations:
• The Intellivox is to be constantly monitored in opera-
tion.
• The physical location of the Intellivox makes access to
the network connector problematical.
• It is not practical (e.g. on a large scale installation) to
configure each device locally.
The RS-485 interface permits multiple Intellivox units to
be “daisy-chained” in parallel, so that they are controlled
by the same PC. In such a system, each Intellivox must
have its own unique network address; this is deter-
mined via WinControl for each individual loudspeaker.
unit 3 unit 2 unit 1
fig.9.1 - Multiple units “daisy chained” in parallel
The network connection should be wired as shown in the
table and diagram below:
fig.9.2 - Network connections
Note that the table above contains information with respect to
5-pin XLR wiring. A 5-pin XLR connector is commonly used to
connect the network to the USB to RS-485 converter.
Note that 2-pair, individually-screened cable should be used
for RS-485 connection. The transmit (Tx) and receive (Rx) bal-
anced data lines must be wired via their own twisted pairs.
JBL Intellivox Installation Manual
CAT-5 type UTP or FTP cable is NOT suitable. Please refer
to the Appendix section of this manual for cable specifica-
tions.
The maximum cable length over which the network
connection will operate reliably depends on the cable type
and the baud rate used. With good quality cable, a safe
maximum figure (at 19.2 kbaud) is 2000 m. If the distance
is significantly longer than this, a network repeater will be
required.
Before connecting multiple devices to the same
network subnet, ensure that their network
addresses do not overlap. Each device should be set to a
unique network address (determined via WinControl).
In some installations, it is normal practice to
disconnect the RS-485 network from the USB to
RS-485 converter at the host (computer) during normal
operation. This removes the possibility of extraneous data
being inadvertently transmitted over the network. In such
a situation, the converter is only reconnected when system
maintenance or checks are required. Disconnecting from
the converter in this way leaves the Rx lines of the
devices unterminated. In most situations this does not
present any problems, but with a large network in a
hostile EMC environment, it is recommended that the
host Y and Z lines (host Tx/device Rx) are terminated in a
100 ohm resistor for normal operation. This can be easily
achieved by plugging the XLR5 female connector into a
spare male connector with the resistor on the appropriate
pins. This termination can then be removed and the con-
verter reconnected when necessary. (If there is any doubt
about which pins should be terminated, shorting all five
pins will generally be equally effective.)
Further information on the RS-485 network can be found in
the RS-485 converter manual and in the WinControl Help files.

Please note that Failure Relay and SPL/Temp
sensor connectors are both of the same type,
do NOT interchange!
*Intellivox devices with early serial numbers do not have
the option of re-configuring the volt-free relay contacts
for impedance-sensing operation. Please contact the
service department for more information.
202007/IvxIM_v2.3
Fault Monitoring
The Intellivox includes a single-pole changeover relay
whose contacts are accessible on the Failure Relay
connector. The conditions under which the relay operates
are defined as part of the device configuration in
WinControl. The relay connections may be configured
either as volt-free, or with additional internal resistors to
allow them to be connected directly to impedance-sens-
ing line monitoring equipment*. This selection is made by
moving an internal PCB jumper, refer to the Appendix for
details.
In volt-free operation, COM is connected to NC; a failure
condition causes COM to be connected to NO.
When configured for impedance-sensing use, the
impedance between COM and NC is 10k Ω and open-cir-
cuit between COM and NO in normal operation. When a
fault condition occurs, the impedance between COM and
NC rises to 20k Ω, and COM is short-circuited to NO.
Impedance-sensing fault monitoring equipment may be
connected to COM and NC.
The relay contacts have maximum current and volt-
age ratings of 100 mA and 24 V respectively.

Fan Control
An external cooling fan should be installed if the ambient
temperature is expected to exceed 40 °C and/or the
Intellivox will be exposed to direct sunlight. Dedicated
forced cooling solutions however can be constructed by
means of the information provided in this section.
An internal temperature-controlled output is available
at two pins of the connector; these pins should be wired
to an external 24 V DC fan as indicated in fig 10.2. One
of the pins is connected to an internal positive supply
rail (FAN+, approximately 24 V), the other one (FAN-) is
driven by an internal transistor. Note that external protec-
tion diodes are normally not required, the FAN- signal is
diode-clamped both to the internal positive supply rail as
well as to the internal GND.
The fan should be a 24 V DC type consuming less than 3
W.
Applicable fan types are:
EBM-Papst 8314.
EBM-Papst 8414.
Sunon KDE2408.
*For Intellivox devices with early serial numbers this
protection is non-resetable. Please contact the service
department for more information.
JBL Intellivox Installation Manual
Please note that the FAN- signal is a PWM
(Pulse Width Modulated) signal. This control
results in a temperature dependent fan speed.
It implies that this signal cannot be used to directly drive
an external relay (e.g. to control a mains-voltage fan).
Contact JBL for details with respect to the interfacing to
mains-voltage fans.
Ensure that the airflow of the fan enhances the
natural airflow (caused by convection).
Note that the supply available at the fan
control connector has a maximum current
rating of 125 mA. Fans or any other loads
consuming more than 3 W should not be connected. This
might result in the activation of an internal protection*.

EXTERNAL AMBIENT SPL/TEMPERATURE SENSOR
The pinout of this connector is as follows:
Although accessed via the same connector, the external
ANS microphone and temperature sensor functions are
independent of each other and either or both may be used,
as required. The use of the optional JBL combined Ambient
SPL/Temperature sensor is recommended, although either
of the two functions may be used alone if wished.

sensor connections
The diagram above illustrates how this connector should
be wired to the optional combined sensor using twin
twisted-pair cable with an overall screen. Note that there
are two AGND terminals on both the Intellivox and the
sensor; care should be taken not to confuse these, and in
particular, not to connect AGND to GND at any time.
202007/IvxIM_v2.3
External Ambient SPL Sensor
The Intellivox incorporates an autogain algorithm which
intelligently alters the volume of the audio according
to the ambient noise level. An internal microphone is
fitted to monitor the ambient noise level in the gaps in
programme material. The autogain function is activated
and adjusted via WinControl. This automatic volume
adaptation feature will only give good results if the signal
measured by the microphone is truly representative of the
diffuse ambient noise level, and in some circumstances it
may be preferable to monitor the ambient noise at a po-
sition remote from the Intellivox itself. Connecting the
external ambient noise sensor automatically disconnects
the internal microphone.
Care should be taken in selecting a suitable location for
the external sensor; it should not be near direct sound
sources such as people talking, air conditioning system
outlets, or other constant noise sources such as electrical
plant, etc. The most favourable external sensor locations
are walls or ceilings (height > 3 m) within the coverage
range of the Intellivox.
Temperature sensor
The external temperature sensor is for activating the
Intellivox’s frost detection system, and should be
connected if it is anticipated that the ambient tempera-
ture may drop below 0 °C. If it does, an internally-gen-
erated pilot tone is applied to the drivers, warming the
voice coils slightly, and thus preventing any build-up
of moisture in the magnet gap. Note that this pilot
tone is always generated if the internal load monitoring
surveillance function is enabled. In that case the ambient
temperature sensor is not required.

MECHANICAL INSTALLATION
Acoustic Centre
Mounting an Intellivox loudspeaker is a straightforward
procedure, but it is essential to understand that the
height of the unit above floor level is extremely
critical. The “correct operational height” is defined as
part of the acoustical design process and the installer
should make sure that he/she has this information before
commencing to mount the Intellivox.
The correct operational height defined by the system
designer is the height of the Intellivox’s acoustic centre.
This point does not necessarily coincide with the position
of any particular physical component on the unit. The
location of the speaker’s acoustic centre is marked by the
centre of the yellow sticker on the front face of the unit
at the time of shipping, and it is this position that must
correspond to the operational height defined in the
design process. The “vertical” position of the acoustic
centre relative to the bottom of the unit varies from
one Intellivox model to another, though it will always
be on the vertical centre line.
JBL Intellivox Installation Manual
fig.12 Sticker showing acoustic centre and unit orientation
When calculating the positions for the mountings (see
page 18), the distance from the acoustic centre to the top
or bottom of the loudspeaker (whichever is being used
as the reference datum) should be measured and then
allowed for when marking the mounting positions. The
model-specific specification sheet supplied with each loud-
speaker includes a mechanical drawing clearly showing
the mounting position locations.
Because of the extreme tight vertical radiation pattern of
the Intellivox, a small deviation from the calculated
acoustical mounting height may cause severe degradation
of the expected performance.
Note also that the yellow sticker indicates
which way is “up”; ensure that this orientation
is observed.
Ensure the protective blue foam behind the grille
and the acoustic center sticker are removed
before operation.

JBL Intellivox Installation Manual
Mounting Options
The Intellivox has two or three (depending on the model)
attachment points at the rear of the enclosure; the device
should be mounted using the appropriate brackets fixed
at these points. Each point consists of four M5
threaded inserts and only the screws supplied with
the original mounting hardware should be used.
The threaded inserts are M5 metric and the
depth is 16 mm.
There are three options for mounting the Intellivox column:
1. The first (and most often used) method is to use the
standard mounting brackets supplied with the unit.
Two or three brackets will be supplied, according to the
Intellivox model. Dimensions of the bracket are shown in
the drawing below.
fig.13.1 - Standard bracket dimensions in mm
The standard brackets allow mounting of the Intellivox 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. If the unit requires three mounting points
(as on the larger Intellivox models) ensure that all three
points are in the same plane, to avoid the unit being bent
when the screws are tightened.
The mounting procedure is given on page 18 under
“Mounting Procedure”.
2. A second method is to mount the Intellivox 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 or three
(depending on the model) swivel brackets are needed. The
horizontal angle of the swivel brackets can be secured
by the hexagonal nut. The swivel brackets are mounted to
202007/IvxIM_v2.3
the rear of the enclosure by the four M5 pan head screws
instead of the standard brackets. Two versions of swivel
bracket are available, permitting the Intellivox to be rotated
through 45 or 90 degrees either way respectively. Refer to
page 22 for ordering information.
fig.13.2 -Direc-
tion of rotation
when using
swivel brackets
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. In this case
longer M5 screws than those supplied will be required,
and it should be noted that the threaded inserts on the
rear of the enclosure are 16 mm deep. 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.
With all mounting methods, it is advised to keep the rear
side of the Intellivox free from the wall in order to prevent
unwanted resonances. If mounting the unit onto or into
a cavity wall, it is advisable to insert rockwool or similar
sound-absorbing material into the cavity in the vicinity of
the loudspeaker.
Accessories are detailed in the back pages of each of the
Intellivox datasheets which can be downloaded from http://

Mounting Procedure
The general mounting procedure using the standard
brackets is described below. It is assumed that all neces-
sary cabling is already prepared with connectors fitted
as described in the previous chapters.
Proceed as follows:
1. Use of the wall plugs and hexagon head screws
supplied is recommended. If using other types, ensure
that the “across-flats” head size does not exceed
11.5 mm (0.45”).
2. Mark and drill the holes (8 mm) for the wall plugs. Use
the two holes with the slots running vertically (refer to
Fig 13.1).
3. Insert the plugs and screws into the holes. Tighten the
screws with a spanner, but stop with a few mm of
screw shaft visible between the head and the wall.
4. Check that it is possible to slide a bracket over the
heads.
5. Check that the chosen mounting points will position the
column in the correct vertical angle specified by the
acoustic design (which is usually exactly perpendicular
to the listening area). Use spacers on one or more of
the brackets if necessary.
6. Using a Philips H2 Screwdriver, attach the brackets to
JBL Intellivox Installation Manual
the Intellivox enclosure with the M5 x 12 pan-head
screws and shakeproof washers supplied. The 10 mm
dia. holes allow screwdriver access to the screw heads.
7. Lift the Intellivox and slide the brackets over the heads
of the hex-head screws protruding from the wall.
8. Firmly fasten the screws securing the brackets to the
wall. Re-check the verticality (or other angle if speci-
fied) with a spirit level or similar levelling device.
9. Remove the front grille(s) from the Intellivox by gently
lifting the grille at the locations of the ‘snap-on’ fittings
which hold it in place. Remove the protective foam.
Unscrew the four self-tapping screws securing the
connector compartment cover and remove the cover.
Thread all cabling through the connector compart-
ment from the rear so that it is free and accessible from
the front.
10. Terminate and plug in all the connectors (see fig 5.1)
and replace the connector compartment cover and the
grille(s)*.
11. Secure grille(s) at each corner with supplied M4 round
head screws and star retaining washers.
*If it is intended to connect a PC directly to the Intellivox to carry out the settings file upload (see page 19), leave the
network connector (if any) unplugged and do not replace the connector compartment cover until the upload and
verification procedure has been carried out.

4.UNIT CHECKS
After installation and connection are complete, the install-
er should upload the settings file into the Intellivox and
verify correct operation with WinControl software.
This section of the manual describes only the file up-
load and a simple verification procedure. It assumes
that a laptop (or other computer) with both WinControl
software and a driver for the RS-485 interface already
installed is available, with the RS-485 interface. It also
assumes that the installer has the settings files, prepared
by the system designer, for each Intellivox loudspeaker
making up the system. These may be elsewhere on the
laptop’s hard drive, or may be supplied separately on re-
movable media such as a memory stick or a CD-ROM. No
previous knowledge of WinControl is necessary, but basic
familiarity with Windows file handling is required.
A full description of WinControl is beyond the scope of
this manual and further information is available in
the application’s Help files. The latest version of
WinControl can be downloaded from http://www.
jblpro.com. Instructions on the use of the RS-485
interface are included with the interface itself.
202007/IvxIM_v2.3
CONNECTING THE PC TO THE INTELLIVOX
If connecting directly to the Intellivox, use the 5-pin XLR
to WAGO cable (supplied with the WinControl Program
Set) and plug the WAGO connector into the loud-
speaker’s network socket. Connect the other end to
the RS-485 output socket on the RS-485 interface. If
the network connection to the Intellivox has been made
permanent and network access is consequently in a
different physical location, connect the PC at this point,
using a different (installation-specific) cable if necessary.
The RS-485 interface should then be connected to the
PC’s USB port.
