age, fault conditions and other param-
eters can be monitored in real-time.
A useful feature of IRIS-Net is the
One Button System Check, that allows
an operator to see a detailed overview
of the operational status of the entire
PA system in less than a minute. IRIS is
able to run an impedance sweep of all
components connected to an amplifier
including connectors, cable, crossover
networks and transducers, and then
store a reference measurement of the
system as it exists, in a given configu-
ration, and in a given environment.
This reference is subsequently stored
in the system and can be exported to
external files on a control PC for future
reference. User definable tolerances
can be applied to these references
allowing an operator to customize the
system supervision for their specific
application. It then compares a real-
time measurement against these refer-
ences and is able to alert the operator
at any time a tolerance is exceeded.
The core of IRIS is based on a
drag-and-drop graphic user interface
that is completely customizable by the
programmer. A library of control and
monitoring graphical user interface
(GUI) elements is provided, and
includes items such as faders, LEDs,
meters, buttons and display elements.
The function and behavior of these
elements is completely customizable
for control surface design.
Today, one of the most frustrating
things for an operator, is to have
access to the tools and features of a
piece of technology, only to find that
they are too complicated to be of any
practical use. As such, IRIS allows the
use of custom graphics and text boxes
in addition to the on-board control
elements. The combination of these
GUI tools allows a programmer to
develop a control surface that is effec-
tive, easy to operate and use for any
customer, regardless of the user’s tech-
nical knowledge.
Additional customization and sys-
tem security is available through the
use of GUI layers within an IRIS proj-
ect. Up to 32 layers can be created
within a project to allow a variety of
different options in which the system
can be monitored and controlled.
Multiple users can be created within
IRIS, each with a unique password
and access to specific layers of the
GUI. This allows a programmer to cre-
ate a control surface that is specific to
the needs of any, and all, operators of
the system. For example, the system
administrator will have access to all
aspects of the DSP and system config-
uration, while other layers can be cre-
ated and password protected for less
technical users, thus allowing them to
access elements such as preset recall,
muting and levels, but prevent them
from changing critical details such as
crossovers and limiters.
From its inception, IRIS was creat-
ed as an open architecture platform
that would be modular and expand-
able to accommodate current and

Additional products are added to the
IRIS shell through the creation of .DLL
files, which are then integrated with
the IRIS core. Over time, the products
IRIS will be able to control will
expand throughout the Telex Pro
Audio family to include Electro-Voice,
Dynacord, Klark Teknik and Midas.
In addition, the IRIS-Net shell is
designed to be used by a variety of
third party hardware to control and
monitor any type of product or sub-
system needed in a typical audio sys-
tem design. Software developer kits
will also be soon available to allow
An extensive arena system design incorporation NetMax.
