RCM-26
Using RCM-26 remote amplifiers
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.
Besides controlling and monitoring amplifiers, the RCM-26 also offers all conventional signal processing functions, like
parametric equalizers, frequency crossovers, delays and limiters. Beyond that, FIR-filters are available to optimize the
amplifiers and loudspeaker system. All DSP-settings can be freely edited and stored in user presets directly on the
module. Independent from network control all DSP settings (filter, delay, level) are maintained incase of failure.
Furthermore, the RCM-26 provides a control port with freely programmable control inputs and control outputs. Control
inputs (GPI's) allow the connection of switches. IRIS-Net offers the possibility to program a variety of logic functions
for the inputs (e.g. switching to an alarm-preset with maximum energy in the speech area). Control outputs (GPO's)
allow the connection of external components, which, for example, are used to signal specific states to peripheral
equipment. Consequently, an amplifier with a RCM-26 module installed corresponds to highest safety requirements.
The RCM-26 has been designed with uncompromising audio quality in mind. Analog audio inputs (internally) and an
AES3 (AES/EBU) digital audio input with XLR-type connector are provided. The use of the digital audio input offers a
dynamic range of 128 dB. Using the analog audio input offers a dynamic range of 120 dB, which, by the way, is an
absolute peak value for digital audio devices.
