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.

Audio inputs
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).
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. For a complete overview of all
features, see Software Manual „NetDesign“.

The Serial interface
RS 232 and RS 485 are operated in parallel by the SpiderLine16. You may only connect one of the two
interfaces at the same time.
RS 232
SPIDERLINE 16
TXRX
The RS 232 interface is used to connect control devices with a maximum cable length of up to 25m, such
as media controls, management systems or indication systems, respectively for the export and logging of
data.
Operated in parallel with the RS 232 interface, to be used for up-mentioned functionalities, for distances of up
to 500 meters of cable. With the RS 485 interface up to 16 devices can be connected in parallel (e.g. ITEC UP
remote control panel).

Signal Ground
(Audio and digital GND)
0 V: The negative pole of the supply voltage should be grounded to avoid ground loops and leakage
currents at only one point with the system. The relevant standards and regulations must be observed.
Chasis Ground: is connected to the metal housing of the Spider16. Usually, this terminal should be
connected with the cabinet or the grounding terminal of the cabinet.
Signal Ground: This Mass refers to all digital inputs and outputs, to the audio in- and outputs (Mic/Line In,
Line Out) and the serial interfaces. Due to the internal use of DC/DC converters, audio transformers and
opto-couplers this mass is not connected to the negative terminal of the 24VDC supply and housing (Chas-
sis Ground).
Usually „Signal Ground“ gets the connection to the ground (earth) through the signal terminals of the
power amplifiers or by connection to other systems and must/should not be connected separately.
DC

Pilot Amp
The SpiderLine 16 operates with three mass-potentials which might be referred to as one mass in a sense,
but they are not interconnected. Thus, it is up to the wiring concept of the system if and where this masses
are to be connected and/or are connected to the earth (ground) of the electric installation.
