Bosch Paviro Digital Public Address System

Product Details:

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 a 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 IRIS-Net.

Features:

• 2 ✕ 500 Watt class D amplifier
• Low power consumption in standby mode (3 Watt)
• Local input per channel
• Excellent sound quality > 104 dB s/n ratio

 

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

 

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.

The PVA-4R24 24 Zone Router is a zone extension for the PAVIRO system. The PVA-4R24 adds 24 zones, 20 GPIs, 24 GPOs and 2 control relays to the system and is controlled and supervised via the CAN bus by the PVA-4CR12 (Controller). Up to 20 external routers can be connected to one controller. One router can handle up to 4000 W speaker load. The maximum load of one zone is 500 W.

The zone indicator lights on the front indicate the current status of every zone:

• Green: Zone in use for a non-emergency purpose
• Red: Zone in use for an emergency purpose
• Yellow: Zone fault detected
• Off: Zone in idle condition

 

Features:

• Routing up to 24 zones from 2–500 Watt
• Low power consumption in standby mode
• Extreme flexibility
• Excellent sound quality > 103 dB s/n ratio
