INPUT A / INPUT B

This indicator lights as soon as the integrated dynamic

limiter is activated and the power amplifier is driven at

the clipping limit or generally at its maximum capacity. Short-term blinking is not a problem, since the internal limiter trims input levels of up to +21dBu down to a S/N-ratio of approximately 1%. If, on the

other hand, this LED lights constantly, reducing the volume is recommended to prevent the loudspeak- er systems connected from being damaged by probable overload

PARALLEL CONNECTION

Connection can be established via the XLR-type input connectors INPUT A / INPUT B or the supplied screw-on connectors which are connected in parallel. In addition, using the PARALLEL-connectors provides the possibility for connecting the input signal through to feed additional power amplifiers, without the need for extra splitter-cables

DSP OUT

The DSP output signal – i.e. the post-digital-signal-processing-unit audio signal – is present at the DSP OUT. The DSP output signal is simultaneously fed to the power amplifier output stage and is correspondingly amplified present at the power amp’s main outputs.

The DSP OUT can be utilized for feeding the digitally processed audio signal from the RCM-24 Re- mote Control Module to additional power amplifiers (without DSP-module); e.g. for increasing the overall output power. With a nominal level of +6dBu and a maximum level of +21dBu (8.7V) the output signal is electronically balanced. Output impedance is 100Ω

CONTROL PORT

The CONTROL PORT offers two freely programmable control inputs and control outputs as well as the reference connections for ground potential and +5V. Using the PC Windows software IRIS, the control inputs can be configured and serve for instance for Power-On / Stand-by switching, preset

switching or parameter control.

The two control contacts IN1 / IN2 are internally set to +5V (open) via pull-up resistors. Activating the control inputs is possible by closing the contacts to ground potential (pin 3) via external switches, pushbuttons or relays.

The two control outputs OUT1 / OUT2 are carried out as Open Collector Outputs. In non-active state (Off) they provide high ohmic resistance. In the active state (On) these outputs are connected to ground. The outputs serve for signalling internal operational states. They can be used for the direct triggering of LEDs, indication lights or relays. The +5V reference connector provides power supply for externally connected appliances with amperage of maximally 100mA. The control outputs allow signal indication of operational states (critical temperature, exceeding or decline of defined limit values, faults, etc.) at central operator desks or to other systems (fire alarm system, general alert system) even with- out PC. For further detail about configuring the control ports, please refer to the documentation accom- panying the IRIS software.

P1200RL, P900RL specifications

Electro-Voice P900RL and P1200RL are high-performance power amplifiers designed for various audio applications, including live sound reinforcement, installations, and studio settings. These amplifiers stand out in the market due to their innovative technologies and robust features, making them suitable for both professional audio engineers and audio enthusiasts.

The P900RL model delivers a powerful 900 watts per channel at 4 ohms, while the P1200RL offers an even more impressive output of 1200 watts per channel at the same impedance. This significant power enables these amplifiers to drive a wide range of loudspeakers proficiently, ensuring clean and dynamic sound reproduction with minimal distortion.

One of the key features of the P900RL and P1200RL is their efficient Class H topology. This technology improves energy efficiency by maintaining high power output with less heat. Class H amplifiers dynamically adjust their power supply voltage according to the input signal, resulting in reduced power consumption and increased longevity of the components. This makes the P series amplifiers not only powerful but also environmentally friendly.

Both models come equipped with a built-in limiter and comprehensive protection circuitry to prevent damage from overheating, short circuits, and overloading, ensuring safety and reliability in demanding environments. Additionally, the amplifiers feature a tri-mode operation, enabling them to be configured for stereo, parallel, or bridged mono setups, providing versatility for various audio applications.

The P900RL and P1200RL also include advanced signal processing capabilities, including a variable low pass filter for enhanced sound control and clarity. The integrated cooling system maintains optimal operating temperatures, allowing for extended use without the risk of thermal issues.

Audio connectivity is straightforward with both XLR and ¼-inch TRS inputs, allowing the amplifiers to interface with a variety of audio sources. The professional-grade output connectors ensure secure and reliable connections to speakers, critical for live sound applications.

In conclusion, the Electro-Voice P900RL and P1200RL amplifiers offer a compelling combination of power, efficiency, and versatility. With their advanced technologies and protective features, they cater to the demanding needs of sound professionals while delivering high-quality audio performance suitable for any occasion.
