Analog inputs: via potentiometer 0 ..
10 V or from multimedia system.
GPIO Control Port:
4 logical outputs, relay contacts SPST
Out 1 potential free for fault signalisation
Out 2..4 referenced to ground,
+5V output can be used to operate external
relays or LEDs with max 200 mA.
Network Topology
These distributors are called hubs or switches.
A hub sends all the signals to every connection.
A switch is more intelligent and sends the data packets only to the
destination where they are needed.
star network.
Network Topology
There are more complex networks (e. g. ring topologies)
that are possible. These must be realised with managed
switches. With these networks, higher safety and
redundancy is possible.
Keywords in these types of networks are Rapid
Spanning Tree– protocol, V-lan, Wireless Lan.
Redundant networks
Network structures for typical stadium
sound systems
From the nonredundant minimum
solution to the maximum redundant
network.

CobraNet
CobraNet is a supplement to Ethernet.
Because of the popularity of Ethernet, all components
are cheap and available in a wide variety. Way to move
audio data over Cat5(6) or Fiber networks.
Specifics to Observe with CobraNet
The audio data is distributed via Bundles. In one bundle, a
maximum of 7 audio channels with 24 bit audio or 8 audio
channels with 20 bit audio can be transported .
The CobraNet-bundle
Specifics to Observe with CobraNet
The capacity of units working with Cobranet is measured in
these bundles (for example, the N8000 can receive 4
bundles and can transmit 4 bundles)
It is important to calculate the necessary bandwidth before
starting a project. For that there is the PC program
CobraCad.
In NetMax we have the possibility to
exchange data with a PROMATRIX – system
The following features can be realised:
announcement/alarm into different Areas
announcement/alarm into different sectors of a PROSOUND area
audio signal from local or networking (RS485) DPM 4000
transmission of different BGM sources into the ELA areas
Transmission of all audio signals via fiber optics, CobraNet, network
Transmission of the RS 485 – signals for networking DPM 4000 via fiber
optics.
Script Files
Script files as advanced programming are extentions of the
operating elements in the IRIS program for use of multiple
commands coming from a single element.
• EV NetMax with IRIS-NET software is the
integrating tool for audio and control
• EV NetMax is the linking component to use
distributed ProSound installations as life safety
standard conform integrated systems
• EV NetMax can be used as audio expansion
for Dynacord ProAnnounce systems
• EV NetMax can be interconnected via data
interface, GPIO‘s and supervisioned audio lines
• User tailored operation, supervision and
administration from e.g. paging consoles, PC or
touch TFT screens and media control systems
• Status and failure signalization „in both worlds“:
