AXYS®Intellivox ADC Installation Manual
This manual describes the recommended installation
procedure for the AXYS®Intellivox ADC range of
loudspeakers.
The ADC range are compact 100 V/70 V line units intended
for use in a wide variety of Public Address and Voice Alarm
(PA/VA) systems. They are particularly suitable for
installation in reverberant spaces such as railway and bus
stations, airports, places of worship, shopping centres, etc.,
where high quality speech reproduction is required.
The AXYS®Intellivox ADC device is a loudspeaker type
known as passive loudspeaker array, in which multiple drive
units are mounted in the housing at specific spacings. In
addition to the drivers, the Intellivox ADC housing contains
a set of passive filters.When properly applied, the Intellivox
ADC device is capable of achieving a constant SPL for mid-
band frequencies over the listening area, whilst minimizing
the 'spill' to other areas.
Other key features include:
• Pilot tone indication
• Protection (glass + thermal fuse and ceramic
terminal block)
• EQ correction
This manual covers:
• Wiring and connection details
• Mechanical installation of the loudspeaker
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 Intellivox ADC range is available in two versions:
• Model V90 – for vertical mounting
• Model H90 – for horizontal mounting
This manual is applicable to both models. However, some
factors arising from the two models’ different physical
configurations result in some sections of the manual text
being strictly applicable to only the V90 or the H90. These
sections are clearly indicated.
Apart from the passive filters, the two models are both
electrically identical and can use the same mounting
brackets. However their effective areas of coverage are very
different, and the decision as to which is specified in a
particular installation will be dictated by the specifics of the
building or space.

AXYS®Intellivox ADC Installation Manual
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.
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.

AXYS®Intellivox ADC Installation Manual
MECHANICAL INSTALLATION
Acoustic Centre
Mounting an Intellivox ADC loudspeaker is a straight-
forward procedure, but it is essential to understand that the
precise mounting location is extremely critical. The correct
mounting location 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 ADC.
MODEL V90 ONLY
The correct operational height defined by the system
designer is the height of the Intellivox ADC’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 of the Model
V90 is towards the top of the unit, as indicated by the
yellow sticker (see fig.3). The horizontal position is on
the vertical centre line.
When calculating the positions for the mountings (see
below), 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
specification sheet supplied with each loudspeaker
includes a mechanical drawing clearly showing the
mounting position locations.
The V90 will normally be mounted perpendicular to the
listening plane, i.e. vertically when the floor is a
conventional horizontal plane. However, if the DDA
investigation has specified a downward angle for some
reason, this angle must be adhered to in the mounting
process.This is likely to necessitate the use of spacers on
the upper mounting bracket.
Because of the tightly-controlled vertical radiation
pattern of the V90, a small deviation from the calculated
acoustical mounting height or vertical mounting angle
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.

AXYS®Intellivox ADC Installation Manual
MODEL H90 ONLY
The location of the acoustic centre of the Model H90 is
in the centre of the unit, both horizontally and vertically.
This is indicated by the yellow sticker on the front grille.
The H90 should be mounted accurately so that
its acoustic centre is at the position identified by the
site survey.
The arrangement of drivers in the H90 differs from the
V90; for this reason, a different set of measurements
needs to be accurately made. For the H90, the critical
aspects of the mounting position are that the horizontal
(long) axis of the enclosure should be precisley
horizontal, and that if the H90 is not being mounted
against a wall (i.e., suspended from a pole or similar
arrangement), the azimuth angle – the angle about the
enclosure’s central vertical axis – should also be exactly
that specified by the DDA survey. Further to these
criticalities, the angle of rotation about the horizontal
axis should also be carefully checked to ensure that the
“downwards” radiating angle of the unit is correct.

MOUNTING OPTIONS
Intellivox ADC models have two attachment points at the
rear of the enclosure; the loudspeaker should be mounted
using these points. Each point consists of four M5 threaded
inserts and only the screws supplied with the original
mounting hardware should be used.
Cavity walls can sometimes be problematical when high-
power loudspeakers are mounted on them. The internal
wall cavity may resonate at one or more frequencies,
degrading the audio performance significantly. Installers
are advised to insert rockwool or similar sound-absorbing
material into the cavity in the vicinity of the loudspeaker
when mounting an Intellivox on a wall of this type.

AXYS®Intellivox ADC Installation Manual
MODEL V90 ONLY
Model V90 only: There are three options for mounting
the Intellivox ADC Model V90:
1. The first (and most often used) method is to use the
standard mounting brackets supplied with the unit.
Dimensions of the bracket are shown in Fig.5.1.
The standard brackets allow mounting of the Intellivox
ADC Model V90 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.
The mounting procedure is given on page 11 under
“Mounting Procedure”.
2. A second method is to mount the Model V90 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 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 brackets are available,
permitting the Intellivox to be rotated through 45 or 90
degrees either way respectively. Refer to page 15 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. 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 (see page 9).
MODEL H90 ONLY
Model H90 only: Unlike the V90, considerable flexibility
exists in the mounting possibilities of the H90. The H90
is not specifically designed to be mounted on a vertical
(or angled) wall.The method of mounting employed in a
particular installation will be primarily dictated by the
downwards angle at which the H90 needs to be
mounted to achieve the coverage calculated during the
DDA analysis.
Custom mounting hardware may be required to achieve
the correct mounting angle. Small mounting angles may
be realised using the standard mounting brackets
(supplied) in conjunction with suitable spacers.
The standard mounting brackets supplied with the unit
may be employed if the Model H90 is to be fixed “flat”
onto a vertical wall.

MOUNTING PROCEDURE
The general procedure for mounting the Intellivox ADC
Models V90 or H90 using the standard brackets is described
below. It is assumed that cabling for connection to the
100 V/70 V line system has been run to the loudspeaker
location.
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. For the
V90 use the two holes with the slots running vertically as
reference. For H-90 use the slotted hole in the centre of the
bracket as reference.
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 (in the case of the Model V90, this is
usually exactly perpendicular to the listening area). Use
spacers on one or both brackets if necessary.
6. Attach the brackets to the rear of the loudspeaker using
the M5 x 12 pan-head screws and shakeproof washers
supplied. The 10 mm diameter holes allow screwdriver
access to the screw heads.
7. Remove the front grille from the loudspeaker by gently
lifting it 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.
8. Lift the loudspeaker and slide the brackets over the
heads of the hex-head screws protruding from the wall,
and at the same time feed the speaker cable through
the cable entry gland at the rear and into the connector
compartment so that it is free and accessible from the
front. Tighten the rear gland, leaving sufficient free
cable to connect to the terminal block.
9. Firmly fasten the screws securing the brackets to the
wall with the spanner. Re-check the verticality (or other
angle if specified) with a spirit level or similar levelling
device.
10. The loudspeaker connections should now be made –
see section on Wiring Details on page 12.

WIRING DETAILS
When the Intellivox ADC has been mounted in the correct
position, it may be connected up. Connection is
straightforward; having passed the cable through the gland,
connect the speaker feed to the ‘L’ and ‘N’ terminals of the
ceramic connection block.
The third terminal, marked with an Earth (Ground) symbol,
allows a separate earthing connection to be made to the
loudspeaker. This provides a low impedance circuit to earth
from the metalwork of the enclosure, as often required by
safety regulations. It should also be connected to a good
electrical earth if the system includes load monitoring
equipment which is is able to detect a short-circuit
condition between one of the 70/100 V lines and ground.
Note that this does not apply to the integral load
monitoring of the AXYS®PB400/800 Industry Amplifiers; if
these amplifiers are being used, the Earth terminal does not
need to be connected for surveillance purposes.
TAP SETTING
The internal 100 V/70 V transformer’s primary tapping
should be set according to the power requirements of the
installation. This figure will have been determined at the
time of site analysis; see also the Maximum SPL figures in
the specifications table on the data sheet.
Always ensure that the amplifier is powered
down before making any changes to the tap
settings as if the audio suddenly becomes live there is a
strong risk of electric shock.
The tapping is set by moving the internal glass fuse to the
appropriate fuseholder. Three fuseholders are located
behind the inspection plate, labelled 100 W, 50 W and 25
W. These figures relate to the speaker use on a 100 V line
system, lower powers are available from a 70 V line system.

CORRECTION EQ
Many building PA systems will include some provision for
equalisation (EQ) adjustment at the signal processing stage,
or within the power amplifier (as with the AXYS®PB-400 and
PB-800 amplifiers).Adjusting EQ to achieve maximum system
intelligibility is a normal part of the commissioning process,
though it should be noted that measured intelligibility will
be greatly affected by several other factors not immediately
under the deisgner's control, such as reverberation time and
ambient noise levels. If external EQ adjustment is not
available, it may be desirable in some applications to modify
the HF response of the loudspeaker itself.
The HF response is altered by repositioning a pcb jumper.
The jumper may be accessed by removing the driver shown
in fig 10.1.
The factory default setting is with jumper towards white
power resistors (rear of enclosure).This enables the internal
correction EQ.The jumper setting towards the front disables
the correction EQ. Note that reducing the HF response may
have the effect of making the unit sound slightly dull, and
the appropriate setting will be determined by trial.
SECURING THE FRONT GRILLE
Option 1. After making the connections and setting the
power tapping, the front grille may be replaced. Do not
replace the protective foam! Align the four locating spigots
with the four larger holes in the back of the grille frame
and push the grille back on, ensuring that all four spigots
locate positively with the retaining clips within the holes.
Option 2. If wished, the front grille may be secured more
permanently with the (supplied) M4 security screws. These
need to be fitted one at a time before replacing the grille.
Insert a screw through the larger hole in the corner of the
grille rear flange by feeding it from the inside of the flange,
so that the thread of the screw protrudes from the rear of
the grille. Push a retaining washer (supplied with the
screws) over the screw thread, and up against the
metalwork to retain the screw in position. Repeat for the
other three corners.
Push the grille into place using the locating spigots as
previously described. Insert the hex key supplied through
holes in the grille itself to tighten the security screws into
the M4 tapped holes.

AXYS®Intellivox ADC Installation Manual
PILOT-TONE INDICATOR
In many PA/VA systems, a high-frequency pilot-tone is
continuously fed to the loudspeakers for load monitoring
purposes. This permits load and cable integrity to be
constantly verified.An LED is fitted to the front panel of the
ADC range of speakers, which illuminates on detection of a
pilot-tone. The LED is visible with the grille installed, and is
a useful check that the system is operational.
The AXYS®PB-400 and PB-800 amplifiers include a suitable
pilot-tone generator; other manufacturers’ equipment may
also be suitable. The pilot-tone should be in the frequency
range 19 to 25 kHz, and of at least 5 Vrms amplitude
(relative to the 100 W tap setting) for the LED to illuminate.
Pilot-tones of other frequencies and/or levels may be used
if the fault monitoring system demands them; the
illumination of the LED is not essential for such a system to
operate correctly.
SPEAKER PROTECTION
In a PA/VA system, it is important that the failure of a single
loudspeaker does not incapacitate the rest of the system.
The ADC range of speakers incorporate three protection
systems to prevent this.
1. The glass fuse used to select the internal transformer
tapping is designed to protect against excessive current
being drawn by the unit. The fuse is a standard 20 mm
diameter 1 A anti-surge type. Only replace this with a
fuse of the same type and rating. In the event of the
fuse needing replacement, remove the fuseholder from
the PCB (noting the tap setting). The fuse can be
removed from the holder by inserting a small
screwdriver or similar through the holes in the top of
the holder. Refer to fig. 9.1
2. ADC units also incorporate a separate thermal fuse in
series with the 100 V/70 V input. This is intended as fail-
safe device, which goes open-circuit if the internal
temperature becomes excessive, such as would occur
in the event of a fire. Thus a local fire which damages a
single speaker on a system does not cause other
speakers elsewhere to fail, as the damaged unit is
removed from the speaker circuit.
3. A ceramic connector ensures that the terminal will not
melt in a fire situation and short out the audio line.
