The PVA-2P500 class-D amplifier is a 2 ✕ 500 W

professional audio amplifier for evacuation purposes.

It can be operated from both the mains and a DC

supply. The output voltage is galvanically insulated and

is constantly monitored for ground fault. An energy-

saving mode and temperature-controlled fans reduce

energy consumption and noise levels. The control and

monitoring functions are performed via CAN bus. This

amplifier is designed for operation in an emergency

evacuation system. The amplifiers are usually

controlled via a controller and configured using IRIS-

Net.

The power amplifier has the following features:

• Floating 100 V or 70 V power outputs

• High efficient amplifier blocks in class-D technology

• Outputs idling and short circuit-protected

• Mains operation 120–240 V (50/60 Hz) and/or 24 V

DC emergency backup

• Electronically balanced inputs

• Temperature monitoring function

• Pilot tone and ground fault monitoring function via

PVA-4CR12 controller or PVA-4R24 router

• Processor control of all functions

• Monitoring of the processor system via watchdog

circuit

• Non-volatile FLASH memory for configuration data

• Internal monitoring function

• Integrated audio relays

• Line monitoring function

The power amplifier is processor-controlled and

equipped with extensive monitoring functions. Line

monitoring for the CAN bus and for audio transmission

allows line interruptions and short-circuits to be

detected and indicated to the user.
