Intellivox ADC Installation Manual

3. INSTALLATION GUIDE

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.

*Authorised electro-acoustic consultants or 'build & design' sound contractors can apply for a DDA License free of charge.

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.
