JBL Intellivox Installation Manual
201401/IvxIM_v2.2
This manual describes the recommended installation
p
rocedure for the JBL Intellivox DC (DDC2.0) and DS (DDS)
range of loudspeakers.
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 addition 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 our website for
further details.
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-Intellivox-DC115, DS115 and DSH115* (fig.1a)
Intellivox-DC180, DS180 and DSX180 (fig.1b)
Intellivox-DC280, DS280, DSX280 and DSX280HD** (fig.1c)
Intellivox-DC380, DS380 and DSX380 (fig.1d)
Intellivox-DC430, DS430 and DSX430 (fig.1e)
Intellivox-DC500, DS500 and DSX500 (fig.1f)
The DS and DSX models use a different DSP algorithm from
the DC models, and 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.

JBL Intellivox Installation Manual
A standard option applicable to all models is the position
within the housing of the electronics module, which may
e
ither 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.
A further option available to special order is for the
electronics module to be mounted at the rear of the unit.
This results in a loudspeaker with different dimensions from
the standard models, requiring a different mounting
procedure. Note that this manual is NOT applicable to these
versions; please contact JBL for more information.

JBL Intellivox Installation Manual
201401/IvxIM_v2.2
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

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 power
failure, will be automatically reloaded on power-up. The
system designer will have determined whether a permanent
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 foilscreened 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
connection 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. For
outdoor applications a weather-proofing kit is available as
an option (see accessories in the appendix).
• Ambient Noise Sensing: the Intellivox is equipped with
a built-in microphone to provide a signal for its embedded
autogain algorithm, but an external ambient microphone
(available as an option*) should be connected if specified
by the system designer. Standard screened two-core
microphone cable should be used for this purpose.
• Frost protection: the Intellivox is equipped with a frost
protection system which activates an internally generated
pilot tone if the ambient temperature drops below a pre-
determined threshold. The frost protection thresholds can
be set using WinControl. If this function is required, an
external ambient temperature sensor (available as an
option*) should be connected with screened two-core cable
(or similar) for its correct operation.
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.
*Note that the optional external ANS microphone is combined with a temperature sensor in a single unit (JBL Order Code
97661101). If both functions are required, the use of 2-pair screened cable is recommended.

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.
A pre-made IEC mains cable (with the appropriate plug for
the territory) may be used if one of a suitable length is
a
vailable. 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.
A stranded wire clamp is available from JBL to make the
transition from rigid mains installation wiring to stranded
appliance cable, should no suitable mains outlet or
connection plate be available. Refer to page 22 for ordering
information.
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
A
ll 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 connector 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
insert 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.
3) Using the wire insertion tool supplied as shown below,
open the clamp contact in the connector shell by pressing
i
nwards towards the shell.
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
T
he Intellivox is normally supplied with two transformer-
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:
If the source equipment has a well-designed balanced
output and the wiring strategy shown below is used, there
s
hould 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.

JBL Intellivox Installation Manual
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 operation.
• 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 determined via
WinControl for each individual loudspeaker.
The network connection should be wired as shown in the
table and diagram below:
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) balanced
data lines must be wired via their own twisted pairs.
CAT-5 type UTP or FTP cable is NOT suitable. Please refer to the
A
ppendix section of this manual for cable specifications.
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 converter 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.

FAULT MONITORING/FAN CONTROL CONNECTOR
T
he pinout of this connector is as follows:
Although accessed via the same connector, the fan control
and failure relay functions are independent of each other
and either or both may be used, as required.
The diagram above illustrates how this connector may
typically be wired.
Please note that Failure Relay and SPL/Temp
sensor connectors are both of the same type,
do NOT interchange!
Fault Monitoring
T
he 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-sensing 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-circuit
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 voltage
ratings of 100 mA and 24 V respectively.

JBL Intellivox Installation Manual
Fan Control
A
n 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. For outdoor
applications JBL offers an off-the-shelf solution (see
weather-proofing kit in the appendix). 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 protection 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.
Please note that the FAN- signal is a PWM
(Pulse Width Modulated) signal. This control
r
esults 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).
C
ontact 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*.
*For Intellivox devices with early serial numbers this
protection is non-resetable. Please contact the service
department for more information.

EXTERNAL AMBIENT SPL/TEMPERATURE SENSOR
T
he 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.
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.
E
xternal Ambient SPL Sensor
T
he 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 position 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 temperature
may drop below 0 °C. If it does, an internally-generated
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.

JBL Intellivox Installation Manual
MECHANICAL INSTALLATION
A
coustic Centre
M
ounting 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.
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 loudspeaker 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 is 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.
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 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.
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.

range of optional brackets for various situations can be

JBL Intellivox Installation Manual
Mounting Procedure
The general mounting procedure using the standard
brackets is described below. It is assumed that all necessary
c
abling 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
the Intellivox enclosure with the M5 x 12 pan-head
s
crews 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 specified)
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
compartment 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.

JBL Intellivox Installation Manual
After installation and connection are complete, the installer
s
hould upload the settings file into the Intellivox and verify
correct operation with WinControl software.
This section of the manual describes only the file upload
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 removable 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. Instructions on how to install
WinControl on a PC are included with the Program Set.
Instructions on the use of the RS-485 interface are included
with the interface itself.
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 loudspeaker’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.

COMMON ANALOGUE GROUNDING ISSUES
C
orrectly connecting the Intellivox to ground has several
benefits:
1. Safety. The GND terminal of the IEC mains connector
provides a direct low impedance path from the
metal parts of the chassis to ground. Always
connect this terminal.
2. Reduction of RF emission. Although the Intellivox
electronics module is well shielded and external
connections are decoupled to prevent RF emission from
the internal high speed digital circuits, this protection
will not work properly if the chassis is not connected to
ground.
3. RF Immunity. RF currents induced in the signal cables by
external RF fields are effectively shorted to chassis-
ground, provided that the cable screen (shield) is of
sufficiently low impedance.
In addition to the mains ground, the Intellivox connector
block has ground pins marked in 3 different ways. Each
serves a dedicated purpose and care should be taken that
they are not interchanged or connected to each other.
• Pins marked GND are connected internally directly to
the chassis of the Intellivox. There are GND pins on the
audio line input connector and the ambient SPL
mic/temperature sensor connector. These GND pins are
for connecting the screen (shield) of the audio and
sensor cables.
• Two pins marked AGND are fitted to the ambient SPL
mic and temperature sensor connector, and serve as a
signal reference only. AGND should not be connected
to any other ground pin (GND or DGND) on the chassis.
• The RS-485 connector has one pin marked DGND and is
intended as a terminal for the network cable screen
(shield). Since the RS-485 interface is optically isolated
(to prevent ground loops), DGND has no relation to the
chassis ground. DGND should not be connected to any
other ground pin (GND or AGND) on the chassis.
SOFTWARE AND FIRMWARE UPDATES
T
he WinControl application is freely available and can be
downloaded from the download area of our website;
http://www.jblpro.com. We advise installers, users and
engineers to check our site regularly for updates. Intellivox
firmware and DSP software upgrades will also be made
available through the website.
For further information about how to use WinControl please
refer to the WinControl Help files.
NETWORK CABLES
The type of cable necessary for correct operation of the
RS-485 network is twin twisted pair with each pair individually
shielded. Numerous cables of this type are readily available
and cables broadly meeting the specifications of the
example cable given below are likely to be suitable.
Example of a preferred cable type:

FAILURE MONITORING ON 70 V/100 V
CONNECTION.
If the Intellivox is equipped with an input module that
supports direct interfacing to a 70 V/100 V signal, a simple
failure monitoring scheme requiring no additional
connections can be easily implemented.
This scheme is based on impedance switching of the first 70
V/100 V input. An amplifier that is driving this input should
be capable of detecting changes in connected impedance.
Impedance switching is supported for input boards PCB960
(see fig 16) and PCB124 (see fig 17). Configuration details
of the impedance switching are depending on the input
board type as described hereafter.
Reconfiguring the failure monitoring requires
access to an internal jumper.
This requires the electronics module to be carefully
removed from the enclosure by a qualified engineer.
Ensure that all connectors are unplugged before removing
the electronics module.
C
onfiguring PCB960
T
he impedance between pin 1 and 2 of the audio input
connector has two states:
• High impedance (approximately 100 kOhm @ DC).
• Low impedance (approximately 2.2 kOhm @ DC).
The states are switched by a separate change-over contact
of the Intellivox's internal Failure Relay.
An internal jumper (JMP1) on the input board determines
the impedance states:
• Low impedance if the device status is OK, High
impedance if the device has a failure or is not powered. This
is the factory default configuration, the jumper is placed on
the contact pins of JMP1 that are closest to CONN1
(furthest away from the edge of the board, see fig 16).
• High impedance if the device status is OK, Low
impedance if the device has a failure or is not powered. The
jumper should be placed on the contact pins of JMP1
closest to the edge of the board.
• Always High impedance, regardless of the device status.
The jumper should be removed.

he impedance between pin 1 and 2 of the audio input
connector has two states:
• High impedance (approximately 140 kOhm @ DC).
• Low impedance (approximately 2.2 kOhm @ DC).
The states are switched by a separate change-over
contact of the Intellivox's internal Failure Relay.
An internal jumper (JMP2) on the input board determines
the impedance states:
• Low impedance if the device status is OK, High
impedance if the device has a failure or is not powered.
This is the factory default configuration, the jumper is
placed on both contact pins of JMP2 (see fig 17).
• Always High impedance, regardless of the device status.
The jumper should be removed.
Notes
• The fault conditions that result in impedance switching
are user definable (these are the same as for the internal
Failure Relay, see section Fault Monitoring on page 13 for
details).
• The High impedance state is affected by the option 'DC
blocking' (as for example offered by part # 381005). In
case of the 'DC blocking' option, series capacitors result
in a very high input impedance for DC. The Low
impedance state is not affected by the 'DC blocking'
option.

FAILURE RELAY CONFIGURATION
Intellivox units equipped with input board PCB124 (see
fig.17) support configuration of the internal Failure Relay
for either volt-free or impedance-sensing (10k / 20k Ω)
operation.
Reconfiguring the internal Failure Relay
requires access to an internal jumper.
This requires the electronics module to be carefully
removed from the enclosure by a qualified engineer.
Ensure that all connectors are unplugged before
removing the electronics module.
An internal jumper on the input board (JMP1) defines
the operation:
• Volt-free mode:
In volt-free operation, COM is connected to NC; a
failure condition causes COM to be connected to NO.
This is the factory default configuration, the jumper is
placed on the contact pins of JMP1 that are closest to
R29 (furthest away from the edge of the board, see fig 17).
• Impedance sensing mode:
When configured for impedance-sensing use, the
impedance between COM and NC is 10k Ω and opencircuit 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. The jumper should be placed on the contact pins
of JMP1 closest to the edge of the board.
