Congratulations! With buying an Electro-Voice PRECISION SERIES power amplifier you have chosen
an appliance that employs the most advanced technology.
P-Series power amps combine outstanding audio performance, highest reliability and operational
stability. Each power amplifier employs an RCM-24 Remote Control module allowing centralized
configuration, control and monitoring of all relevant power amp parameters (like output current, output
voltage, load impedance, etc.).
The gapless protection circuitry concept not only prevents the power amp itself but also the connected
loudspeaker systems from being damaged. These extensive protections include Dynamic Audio
Limiters, DC/HF-Protections, Back-EMF-Protection, Inrush Current Limiter, Short Circuit Protection
and of course Thermal Overload Protection for the output transistors and mains transformers.
Four-speed high performance fans guarantee outstanding thermal stability at absolute low running
noise. The ventilation is directed front-to-rear allowing trouble-free operation even in smaller amp-racks.
Comprehensively dimensioned power supply units with low-leakage toroidal transformers provide
extensive headroom far above the stated nominal power.
Mechanical construction and workmanship also comply with the highest precision manufacturing
standards. The rigid sheet steel chassis resists even the most wearing tour operation.
The RCM-24 provides full-size
overview of the system’s entire status
and control over all relevant system
parameters at any time.
The RCM-24 module allows integration into a Remote Control Network consisting of up to 250 power
amps. The Windows Software IRIS – Intelligent Remote & Integrated Supervision – allows controlling
and monitoring an entire PA-system from a single or several PCs. Any operational status like initial
power-on status, temperature, modulation, limiting, activation of protections, deviation in the load
impedance, etc., are centrally registered and displayed, which provides the opportunity to take specific
measures prior to the occurrence of critical operational states. Programming an automatic response for
exceeding or falling below specific limits is possible as well. All parameters, e.g. power-on/off, levels,
muting, filters, etc. can be controlled in real-time and saved in any power amp.
Monitoring the connected loudspeaker systems is performed through measuring output currents
and –voltages of the two power amplifier channels. Each time the signal falls below or exceeds set
limit values is immediately indicated and logged, thus detecting and indicating short circuits and line
interruption during normal operation. The integrated impedance test function allows more precise
checking the connected loudspeaker systems. The integrated signal generator is employed together
with the current/voltage testing to measure the connected loudspeakers’ and cable’s impedance
plus over the entire frequency range. The resulting impedance graph is displayed on the PC-screen.
Comparing the measured impedance progression to a reference value is possible at all times, which
allows recognizing even the slightest loudspeaker defects or irregularities.
