Introduction
The IRIS-Net software (Intelligent Remote & Integrated Supervision) runs under Windows and allows configuring,
controlling and monitoring a complete PA-system from a single or from several PCs. Any operational status, e.g. power-
on, temperature, level, limiting, activation of protections, deviation of the output impedance, etc., are centrally
recorded and displayed, which offers the opportunity to react and interfere even before the occurrence of critical
operational states. Programming automated actions that are carried out when exceeding or falling short of certain
threshold values is possible as well. All parameters, e.g. power-on/off, level, mute, filters, etc. are controlled in real-
time and can be stored in any power amplifier.
Monitoring the connected loudspeaker systems is performed by continuously measuring output currents and voltages
of individual power amplifier channels. Each exceeding or falling short of set thresholds is instantly signaled and
logged. In this way, short-circuits or line interruptions, as they might occur during normal operation, are recognized
and displayed immediately. The integrated impedance test function allows checking the connected loudspeaker
systems more precisely. Together with the current/voltage testing function the integrated sweep-generator is employed
to measure the connected loudspeakers' and cables' impedance over the entire frequency range. The resulting
impedance graph is displayed on the PC-screen. Comparing the measured impedance progression with a reference
value is possible at all times, which allows recognizing even the slightest defects or irregularities of the loudspeaker
systems.
Next to its controlling and monitoring capabilities, the IRIS-Net System provides comprehensive signal processing
functions. A total of 20 parametric filters, X-over functions, delays, routing and level control as well as compressors and
limiters per each channel are included. All parameters can be freely edited and stored in up to eight user presets within
the remote amplifiers. Independent from network control all DSP settings (filter, delay, level) are maintained incase of
failure. Additionally, the control inputs of the power amps can be used for network-independent switching to another
preset (e.g. alarm settings with maximum energy for voice and text announcements).
Therefore, the IRIS-Net System fulfills even the highest safety requirements.
