PVA-4CR12

The Bosch PVA-4CR12 Controller serves as the core paging manager for the PAVIRO system, handling all audio processing, supervision, and control for a comprehensive voice alarm and paging solution. It features eight local audio inputs that can be routed to four audio outputs and includes a two-channel message manager for efficient communication.

A single PVA-4CR12 controller supports up to 16 call stations, 492 paging zones, and can manage up to 2000 W of loudspeaker load. With 12 zones, 18 General Purpose Inputs (GPIs), and 19 General Purpose Outputs (GPOs), the system’s scalability is further enhanced by supporting up to 20 external routers and 40 amplifiers (each offering 2 × 500 W) to extend zones and power capacity.
