DSPPA PAVA8500E 8 Zones Integrated Voice Alarm PA System Extender Amplifier in Bangladesh

The DSPPA PAVA8500E 8 Zones Integrated Voice Alarm PA System Extender Amplifier is a powerful and reliable solution designed for expanding large-scale voice evacuation and public address systems. With a rated output power of ≥500W (100V), it delivers robust and clear audio across up to eight zones, making it ideal for commercial buildings, transportation hubs, schools, and industrial facilities. This amplifier ensures high performance with both emergency mic and line inputs, offering excellent input sensitivity (5 mV/600 Ω for emergency mic and 1000 mV/10 kΩ for line) and maintaining harmonic distortion at less than 1% at 1 kHz. The frequency response range covers 80 Hz–15 kHz for the emergency mic and 50 Hz–18 kHz for the line input, providing crystal-clear, full-range sound reproduction. With a superior signal-to-noise ratio of >75dB (emergency mic) and >80dB (line), the PAVA8500E guarantees minimal background noise for crisp communications. The system features robust control capabilities, including system fault relay outputs, emergency mode relay outputs, and 8 dry contact inputs and outputs, all operating in a short-circuit, no-voltage mode for secure and reliable signal transmission. It also supports level mode inputs from 3.3V to 24V. Integrated voice message management utilizes WAV files stored on an SD card, with data retention exceeding 10 years, ensuring readiness in critical moments. Designed for resilience, the PAVA8500E operates on both AC 220–240V and DC 24V/30A, with low voltage protection (20±1V) to maintain system stability. Its battery system supports a rated charging current of 3.8A and a maximum amplified current of 5A, ensuring uninterrupted operation during power outages. The amplifier is housed in a durable and compact chassis (483×420×132mm) and is packaged securely (550×510×215mm) for transport and installation. Built to meet the demands of modern safety and communication standards, the DSPPA PAVA8500E provides an essential extension for comprehensive voice evacuation systems, combining power, clarity, and reliability in one integrated solution.
