SPIDERLINE 16 - 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 SpiderLine16 has emerged and
grown. In addition, all our know-how from many years of experience in the field of audio and digital technolo-
gy 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 SpiderLine16, 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
SpiderLine16 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 SpiderLine16 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).
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 „mass concept“).
When installed in switch cabinets, pre-cautions need to be taken to ensure sufficient air exchange to avoid
overheating of the device.
Due to the great depth of the housing, support rails are absolutely necessary for installation
in 19“ cabinets.
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 re-
paired 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. Improper installations in fur-
niture, 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, measure-
ment data and IOs are controlled and transmitted. With four audio inputs, four audio outputs, serial ports and
I/Os the SpiderLine16 is one of the most important system components.
