The PVA-2P500 class-D amplifier is a 2 x 500W 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 energy­saving 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 IRIS­Net.
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

• 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

• Pilot tone and ground fault monitoring function via
PVA‑4CR12 controller or PVA‑4R24 router

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.
