Short information
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. It can be used as system amplifier or in stand-alone mode. The
amplifiers are usually controlled via a controller and configured using IRIS-Net.
The power amplifier has the following features:

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.
