SPIDER 44/02 / SPIDER 04/02 - INTRODUCTION
Dear Customer,
The main focus of our research work is and always has been the development of practical devices that are
flexible, versatile, reliable, future-proof but still easy to handle. In close cooperation with electrical consultants,
system architects and operators of public address systems the ITECNET Spider44 / Spider04 has emerged
and grown. In addition, all our know-how from many years of experience in the field of audio and digital tech-
nology has been integrated into this product.
Unlike any other known device, it offers the possibility of building the largest and most complex audio systems,
with relatively simple and well arranged operation and configuration.
This manual describes the hardware of the Spider 44 / Spider04, shows the construction and the wiring of the
various audio and logic I/Os and thus serves the audio system designer / integrator in the conceptual design
phase respectively during the set-up process of audio networks. Numerous examples illustrate the optimum
usage and the professional installation of controls and other devices.
For knowing the entire system, all its possibilities and for executing the necessary configuration tasks the
software manual is required in addition. Please observe during the installation / operation of the ITEC Spider
44 / Spider04 all listed safety instructions in this manual; furthermore data and examples provided ensuring
the optimum usage of the device.
Lots of joy and success - The ITEC Acoustics Team

Safety instructions
When installing the device, the local connecting conditions, the required protective measures and all relevant
standards have to be observed. The installation and configuration of the ITEC Spider 44 / Spider04 must be
performed by trained personnel only. For the configuration the original software ITEC NetDesign has to be
used exclusively.
The power connection is carried out via the original power supply unit or directly to any existing 24 V DC
power supply (emergency current).
The power supply has on its primary side a rubber connector and is linked with an appropriate cable to the na-
tional standard AC outlet (115 - 230 volts). Please note that the ground connector of the device (audio ground
and ground of all digital audio interfaces) is electrically not connected to the negative pole of the DC supply.
Please observe during the installation, that no multiple connections between the ground connector of the
device and the 24 V negative pole are put in place (see also chapter „power“).
When installed in switch cabinets, pre-cautions need to be taken to ensure sufficient air exchange to avoid
overheating of the device.
When connecting to other devices (e.g.: sound sources, computers), the exact pin configuration and the spe-
cifications of inputs and outputs need to be observed.
Only a connection to networks, which are compliant to IEEE 802.3 (Ethernet), is possible. Never try to open
the device by force or by unscrewing. The product does not contain parts that can be repaired by amateurs.
Please contact the manufacturer or a local distributor.
Do not apply temperatures above 50 °C, humidity larger than 95% or rain to the device.
Caution: Before carrying out any modifications on the device (only by qualified personnel) the power supply
has to be disconnected. The device is designed for installations in 19“ cabinets / rack / frame / housing. Impro-
per installations in furniture, cabinets or distribution systems, as well as free installation have to be avoided.

The audio network ITECNET
ITECNET is a decentralized, Ethernet-based audio network for the simultaneous transmission of up to 64
audio channels with the highest audio quality. At the same time, a huge number of system data, measurement
data and IOs are controlled and transmitted. With four audio inputs, four audio outputs, serial ports and I/Os
the Spider44 / Spider04 is one of the most important system components.

Audio inputs (only SPIDER 44)
The device features 4 balanced inputs, which are XLR connectors on the rear cover.
The maximum input gain is in line operation from -20 to +30 dB, in microphone operation
from +10 to +60 dB for each channel selectable.
Thus, all conventional microphones and media players can properly be adjusted.
Phantom power is switchable per channel (12V).
Optional 24V or 48V phantom power is possible with a plug-in module.
Connection is made to the included power adapter or an existing 24 V DC emergency power supply. The
ground connection of the device (audio ground and ground of all digital audio interfaces) is electrically not
connected to the negative pole of the DC supply. This is especially of importance, when a connection to
peripheral 24 V emergency supplies is made, as the audio grounds, linked to power amplifiers or playback
devices on site, are connected to the ground wire of the according sub-station. Due to the galvanic separation,
loops and shunts can effectively be prevented. A floating guidance of the 24 V supply voltage or to ground at
one spot, usually at the emergency power supply, is recommended.

The device has 8 digital inputs, which are primarily designed for the detection of low-level operating and fault
conditions. This includes the monitoring of fault signals of amplifiers, monitoring of cabinet temperature by
thermostats, etc. A remote control, that is, an output follows at any point of the system the input is also pos-
sible. Each input state can be inverted for further processing by the software.

the operating status is available. In case
the device is not operating or during a fault
condition, the relay is released, during normal
operation it is activated.

Speaker line monitoring (optional)
The speaker line monitoring is a plug-in board that can be optionally
installed in the Spider44 / Spider04. The four zones of the line
monitoring correspond to the respective audio outputs of the Spi-
der44 / Spider04. It will short circuit, earth fault and the speaker line,
but also break-down or change in level of the amplifier detected.
There are two ways of monitoring line available and therefore the wiring is different:
Line return: The end of a line speaker wire is guided back to the device. A break is detected when the
transmitted signal cannot be detected at the end of the line. Accordingly, branches and branch lines must be
avoided.
Impedance measurement: Using this method the impedance of the connected loudspeaker line is
continuously measured in operation and compared with one, once defined as a reference impedance value.
Deviations in the range 10 - 20% (adjustable) can reliably be detected. Using the impedance measurement,
the return of the speaker wire to the terminals “RET” can be omitted.
