The PVA-2P500 is a high-efficiency, dual-channel Class-D amplifier designed specifically for public address and emergency evacuation systems. Delivering 2 × 500 W output at 100 V or 70 V, it supports both AC (120–240 V) and 24 V DC backup power sources, ensuring reliability during power failures. The amplifier features galvanically isolated outputs with continuous ground fault monitoring and is protected against idling and short circuits. It includes temperature-controlled fans for quiet, energy-efficient operation.

All functions are processor-controlled, with extensive system and line monitoring via CAN bus. Integration with PVA‑4CR12 controllers or PVA‑4R24 routers enables pilot tone, line, and ground fault monitoring. The unit also includes audio relays, electronically balanced inputs, watchdog circuit, non-volatile memory for configurations, and internal diagnostics—making it ideal for life safety and critical audio installations.
