JBL Professional Intellivox ADC Installation Manual

2. INTRODUCTION

This manual describes the recommended installation
procedure for the JBL 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 JBL 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 and high-pass filter
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.

APPLICABLE MODELS, AND VARIANTS
The Intellivox ADC range is available in two versions:
• Model V90 – for vertical mounting
(Part Nos. 576125, 577125 and 577135)
• Model H90 – for horizontal mounting
(Part Nos. 576126, 577126 and 577136)
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.
