1. IMPORTANT SAFETY INSTRUCTIONS

200905/ADCIM_v1.0

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.

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.

range of optional brackets for various situations can be

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.
