SPIDERMIKE 2 -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
ITECNET has emerged and grown. In addition, all our know-how from many years of experience in the field
of audio and digital technology have been integrated into this product
ITECNET allows the build-up of the largest and most complex audio systems, with relatively simple and clear
operation and configuration.
SpiderMike 2 is the base station of the ITECNET system. Due to its modular design, digital IO‘s, analog inputs
and a serial interface, it offers beyond its function as a base station, a large number of monitoring and control
functions.
The integrated SD card reader / player allows the storage and playback of alarm texts, announcements, jing-
les or even whole pieces of music in CD quality.
This manual describes the hardware of the spider mike 2, showing the construction and operating of the
various audio and logic I/Os and thus serves audio system designers and system architects during the
conceptual respectively installation phase of audio networks.
Numerous examples illustrate the optimal use and the professional installation of operating controls and
other devices.
For knowing the entire system, all its possibilities and for executing the necessary configuration tasks the soft-
ware manual is required in addition. Please observe during the installation / operation of the ITEC SpiderMike
2 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 SpiderMike 2 must be performed
by trained personnel only. For the configuration the original software ITEC NetDesign has to be used exclu-
sively.
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 supply“).
The device is designed for a free putting or for an installation in a 19“ cabinet (bracket for rack assembling as
optional accessory). For cabinet installations please ensure adequate air circulation. Mounting of the device
in closed timber furniture is not allowed.
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 allowed. 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.
Use a dry or slightly damp cloth to clean the housing surface and the keyboard. Aggressive or abrasive cle-
aners should be avoided.
The positioning on the desk has to be done in a way that any impact on the system by spilling of liquids or
by placing objects on the keyboard is prevented. The intercom microphone is part of the system and must be
handled with special care. Strong bending of the swan neck, covers or concealing the microphone as well as
any change or manipulation is not allowed.
In particular in monitored systems for voice alarms you have always to ensure that microphone and integrated
speakers of the device are not concealed.
A disconnection of the microphone during operation triggers a system failure message!
The use of other microphones without consulting the manufacturer or distributor is not allowed!

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.

SpiderMike 2, the station of ITECNET system is unique in terms of flexibility and features. Due to its modular
expandability the direct selection of 20 up to 100 zones can be supported. A second audio input allows
playback of external audio sources, a second output the connection of external amplifiers and speakers.
Through a number of IOs alarm, set-up and control functions can be carried out at any point of the network.

Audio outputs
The first audio output device drives the built-in speaker with an output of 1 watt. A second, balanced line out-
put is designed as plug terminal block in the housing. The maximum output level is +15 dB.
SPIDERMIKE 2
Power supply 24 V DC
Audio inputs
The device is equipped with two balanced inputs, one as a balanced XLR connectors at the topside the other
as a plug-in terminal block. 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).
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 4 digital inputs, which are designed
primarily for the detection of low-level operating and
fault conditions, or for external buttons. A remote con-
trol, which means that an output at any point of the
system follows the input is also possible.
Each input state can be inverted for further processing
by the software.

The Serial interface - RS 232
Used
• For connecting to control units
• As an interface for control stations or fault reporting systems
• For logging and output of data via serial data cable for short distances
The RS 232 interface is also used for the communication with the inter-
com-expansion modules. In this case a further usage of the RS 232 interface
is no longer possible.
