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.
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.
