Product Details:

The PVA-4CR12 controller is the central paging manager for the PAVIRO system. Eight local audio inputs can be switched to four audio outputs. A two channel message manager is integrated. The controller provides all the audio processing, supervision and control functions for a complete PAVIRO system. A single controller supports up to 16 call stations and 492 paging zones. The controller is equipped with 12 zones, 18 GPIs and 19 GPOs. One controller can handle up to 2000 W loudspeaker load. Additional zones and power can be added by using up to 20 external routers and 40 amplifiers with each 2 ??? 500 W. The zone indicator lights on the front indicate the current status of every zone


Other Details:

• Low power consumption in standby mode
• Extreme flexibility
• Excellent sound quality >106 dB s/n ratio
• Up to 85 minutes internal digital message storage

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 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: • Floating 100 V or 70 V power outputs
