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 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:

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.
