Bosch/Power Amplifier,2X500W.
- 2 x 500 W class-D power amplifier (70/100 V output).
- Low power consumption in standby mode.
- Excellent sound quality, high signal-to-noise ratio.
- EN 54-16 system certification.
- 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 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 IRISNet.
The amplifiers are usually controlled via a controller and configured using IRISNet.
