DS-QAZ1A500G1-VB2 - 500W 2-Zone Network Amplifier

The Hikvision DS-QAZ1A500G1-VB2 is a high-capacity, commercial-grade 500-watt 2-zone network audio power amplifier designed to centralize, manage, and automate public address (PA) broadcasting over an IP network. Operating as an intelligent, smart network appliance, this robust 5.6 kg device features flexible audio outputs supporting both 70 V / 100 V constant-voltage configurations and 4 Ω / 8 Ω low-impedance loops, delivering up to 250 W per zone when both channels run simultaneously, or a full 500 W on a single zone. It hosts a broad range of physical and wireless inputs—including multiple 6.35 mm microphone connections, standard analog RCA line-ins, a local USB 2.0 playback port, and Bluetooth 5.0 connectivity—complete with onboard manual mixing knobs for total, bass, treble, and independent channel volume adjustments. Built with 4 GB of internal eMMC storage (with 1 GB dedicated for local media files) and robust circuit protections, the amplifier seamlessly integrates with network security software via ISAPI, ISUP, and SIP protocols to manage scheduled chime/bell tones, real-time live paging, prioritized emergency mass overrides, direct text-to-speech (TTS) synthesis, and automated security event alarm linkages.
