Intellivox 808/1608 Installation Manual Rev 1.1
AXYS
2. INTRODUCTION
This manual describes the recommended installation
procedure for the AXYS® Intellivox DC (DDC2.0) and DS
(DDS) range of loudspeakers, Models DC/DS 808 and 1608.
®
The AXYS
Intellivox is a type of loudspeaker known as
an active DSP-controlled loudspeaker array, which utilises
the principle of mounting multiple, individually-driven
loudspeaker drive units in the vertical plane at specific
spacings. All the Intellivox models covered by this manual
consist of two components: the column loudspeaker unit
and a mains-powered multi-channel power amplifier which
includes a Digital Signal Processing (DSP) section.
The DC/DS 808/1608 models have been specifically
designed for applications where a high SPL is required,
and/or an extended audio frequency response suitable for
high quality music reproduction is desirable.
This manual describes the following aspects of an
installation:
Note that later serial numbers are equipped
with an input board with Phoenix in stead
of WAGO connectors. This manual describes the WAGO
version (early serial numbers). The Phoenix input board is
used from the following serial numbers:
Ivx-DC808 : 011600013
Ivx-DC1608 : 011700010
Ivx-DS808 : 010700016
Ivx-DS1608 : 010800036
The DC/DS808 loudspeaker unit is fitted with six 6.5” lo/
mid-range drivers and two 1” hi-frequency compression
drivers. The DC/DS IntelliAmp supplied with these models
has 8 separate audio channels.
The DC/DS1608 loudspeaker unit is fitted with fourteen
6.5” lo/mid-range drivers and two 1” hi-frequency
compression drivers. The DC/DS IntelliAmp supplied with
these models has 16 separate audio channels.
• Necessarycabling
• Connectorwiring
• Mechanicalinstallation
After installation, the amplifier and
loudspeaker should be tested for basic
functionality using the supplied AXYS

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.)
APPLICABLE MODELS, AND VARIANTS
This manual applies to the following AXYS® Intellivox
models*:
Intellivox-DC808 and DC1608
Intellivox-DS808 and DS1608
The DS models use a different DSP algorithm from the DC
models. This difference may be ignored for the purposes of
installation and commissioning.

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 amplifier’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 at the rack. A cable with two individually foil-screened
twisted pairs should be used. Details of suitable cables can
protection system which activates an internally generated
pilot tone if the ambient temperature drops below a pre-
determined threshold. The frost protection threshold 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.
MECHANICAL INSTALLATION OF THE AMPLIFIER
The IntelliAmp is designed to be mounted in a standard 19”
equipment rack. The front panel is fitted with rackmount ears
for this purpose. The IntelliAmp occupies 3U of vertical rack
space.
Note that due to the weight of the amplifier,
the use of additional rear supports is strongly
recommended. The rear of the unit has additional
mounting points to facilitate this.
Ventilation
The IntelliAmp is forced-air cooled by two internal
temperature-controlled fans. This ventilation method should
ensure that the amplifier remains within its operational
temperature range under most circumstances, but if it is to
be installed in a location of high ambient temperature, and/
or in a rack containing a significant quantity of other heat-
generating equipment (see below), consideration should be
given to climate-controlling the room in which the equipment
rack is situated.
Do not install the IntelliAmp in a 19” rack
immediately above or below another item of
equipment generating a significant amount of
heat (e.g. another power amplifier). Plain 1U blank panels
should be used as spacers. Note that slotted or perforated
ventilation panels should not be used, as these will reduce
the effect of forced-air cooling. Also, be aware of the rear-
to-front direction of airflow of the IntelliAmp ; it is not good
practice to install equipment employing forced-air cooling
with different directions of airflow in the same enclosed rack.
Airflow is via the grilles at the rear (intake) and
front (exhaust) of the amplifier. Ensure that
both sets of grilles are completely clear of any
obstructions within 100 mm (4”) in order to maintain the
necessary airflow.
See page 16 for details regarding the mechanical installation
of the loudspeaker enclosure.
* The IntelliAmp may be ordered with alternative input modules which accept signals directly from 70/100 V distribution
systems. Two modules are available: a) with one normal 0 dBV balanced line level input and one 70/100 V input, b) with two
70/100 V inputs. These options need to be specified at the time of ordering. See page 22 for order codes.
** 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.

CONNECTOR AND WIRING DETAILS
All permanent connections to the IntelliAmp are made
at the rear of the unit. Audio 1 and RS-485 connections
are replicated on the front panel on XLRs, together with
loop-through connectors. This is useful when multiple
IntelliAmps are installed in the same rack.

A 2 m pre-made PowerCon
mains cable with a European
plug is supplied with the unit. If it is necessary to fit a
different type of mains plug, please observe the following
cable colour codes:
TERM EURO USA
L Brown Black
E Green/yellow Green
N Blue White

The orientation of the PowerCon
connector is evident
from the keyway on the centre spigot; insert the plug fully
and then rotate it clockwise until a firm click is heard.
The plug is now locked against inadvertent removal. To
unplug, press the release latch on the side of the plug body
before rotating anticlockwise.

The IntelliAmp is normally* fitted with two transformerbalanced line inputs. Selection of Input 1 and/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.
Inputs 1 and 2 are available on the 6p male WAGO
connector on the rear panel, but Input 1 is paralleled to a
3-pin female XLR on the front panel; this is usually reserved
for use during a temporary installation set-up, but may
used as the permanent audio input if more convenient.
Audio 1 is also wired to an adjacent 3-pin male XLR,
allowing audio to be looped to further IntelliAmps where
required.
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 AXYS
Octadrive) should
have a low impedance balanced output. The nominal line
input level is 0 dBV.

with general techniques that may be applied in order to
reduce ground-induced noise.
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 IntelliAmp and the
sensor; care should be taken not to confuse these, and in
particular, not to connect AGND to GND at any time.

LOUDSPEAKER CONNECTIONS
The standard cable supplied with the unit is 5 m in
length. Longer cables are available, and length should
be specified at the time of ordering. The loudspeaker
cables are terminated in Harting multipin connectors,
male-to-female, and wired pin-to-pin. The DC/DS
808 models use 20-pin connectors, the DC/DS 1608
models use a dual version which provides two 20-pin
connectors in a single shell.

CABLE SPECIFICATIONS
Installers wishing to make up their own loudspeaker
cables should ensure that the multicore cables used
have cores of adequate diameter. The maximum
permissible cable length is dependent on the wire
gauge of the cores. Too high a cable resistance,
resulting either from too small a core diameter, an
excessively long cable length, or a combination of the
two, will result in an unacceptable level of signal loss
between the IntelliAmp and the loudspeaker.
The maximum signal loss that can be tolerated before
the performance of the Intellivox is audibly degraded
is 1 dB. The tables below list the cable lengths which
result in a 1 dB signal loss for various core diameters,
and thus represent the maximum cable length which
can be employed in each case. Installers should
recognise that these are absolute maximum figures,
and work well within these limits.
Note that all cores in the cable must be of the same
wire gauge.
