Hikvision 500W 2-Zone Network Amplifier | DS-QAZ1A500G1-VB2(B)
The Hikvision DS-QAZ1A500G1-VB2(B) is a 500 W, 2-zone network (IP) amplifier for public address systems. It plays audio from the network, USB, Bluetooth, microphones and RCA sources, and supports scheduled, live and emergency broadcasts with alarm linkage and text-to-speech (TTS).
Color: Black
Key Features:
Two Independent Zones: Volume and content can be set separately for each of the two zones, so one area can hear music while another gets an announcement. Each channel delivers up to 250 W when both run together.
Scheduled, Live and Emergency Broadcast: Run timed announcements and music, talk live, or send emergency messages. Alarm linkage and TTS let the amplifier play spoken text automatically when an alarm input is triggered.
Alarm Inputs and Output: One EVAC alarm input, one alarm input and one alarm output let you link the amplifier with fire, security or other systems.
Many Audio Sources: Four 6.35 mm microphone inputs, four RCA inputs, a USB 2.0 port (FAT32/exFAT drives up to 256 GB) and Bluetooth 5.0 (10 m), each with its own volume knob, plus bass and treble controls.
Built-in Storage: 4 GB of internal eMMC storage, with 1 GB for audio files, so you can keep regular announcements and music on the device.
Output Modes: Constant-voltage outputs (100 V / 70 V) for long speaker lines. Hikvision's datasheet for this (B) version also lists constant-impedance outputs (4 Ω / 8 Ω); the mode is set in the web interface and with a switch on the rear panel, and both must match.
Works with: Gigabit Ethernet (RJ45 10/100/1000 Mbps) and Hikvision's ISAPI and ISUP protocols plus RTP.
Good to know: Speakers and microphones are sold separately. Hikvision states the device is for use below 2,000 m altitude. In the box (per Hikvision datasheets): the device, a power cord and the regulatory compliance and safety information sheet.
