The Hikvision DS-QAZ1A1000G1-VB4 is a 1000W 4-zone network amplifier for large PA installations. Over Gigabit Ethernet it supports scheduled, live and emergency broadcasts, alarm linkage and text-to-speech (TTS) with SIP, ISAPI and ISUP integration, and it has a dedicated EVAC alarm input for evacuation messages.
Locally it accepts four microphones, four RCA line inputs, USB (up to 256 GB) and Bluetooth 5.0, with volume knobs for every input and output plus bass and treble. Four constant-voltage outputs (set to 100V or 70V, up to 250W per channel) drive the zones, and RCA and 3.5 mm outputs feed further equipment. It runs on 100–240 V AC.
Note: when the output is set to 100V, connect only speakers rated for 100V – connecting 70V-rated speakers can damage the device.
