Delivering a total output of 500W across two independent audio zones, this amplifier enables users to broadcast different audio content or adjust volume levels separately for each zone. Its intelligent network functionality makes it an ideal choice for schools, offices, shopping malls, factories, hospitals, hotels, warehouses, and transportation facilities where flexible audio management is essential.
Smart Two-Zone Audio Control:
Designed with advanced zone management, the amplifier supports independent volume adjustment and content distribution for two separate speaker zones. Each channel provides up to 250W constant-voltage output, allowing efficient operation with both 100V and 70V speaker systems. This flexibility simplifies installation in medium and large-scale public address systems while ensuring clear and balanced audio coverage throughout the facility.
Multiple Audio Input Options:
The DS-QAZ1A500G1-VB2 offers versatile connectivity with multiple audio input sources. Users can play audio through USB storage, Bluetooth 5.0, RCA inputs, or connect up to four microphones using dedicated 6.35 mm microphone inputs. This wide range of input options makes the amplifier suitable for announcements, background music, emergency broadcasts, meetings, classrooms, and live presentations without requiring additional external equipment.
Intelligent Network Broadcasting:
As part of Hikvision’s IP audio ecosystem, this amplifier supports scheduled playback, live broadcasting, emergency announcements, alarm linkage, and Text-to-Speech (TTS). It communicates through standard network protocols including IPv4, HTTP, HTTPS, SIP, RTP, TCP/IP, UDP, DHCP, DNS, SSH, SSL/TLS, and more. Compatibility with ISAPI, ISUP, and SIP allows seamless integration into Hikvision security and building management systems for centralized audio control.
High-Quality Audio Performance:
Engineered for professional sound reproduction, the amplifier delivers a frequency response of 50 Hz to 20 kHz, providing clear speech and balanced music playback. With less than 0.5% Total Harmonic Distortion (THD) and a Signal-to-Noise Ratio exceeding 90 dB, it ensures clean, distortion-free audio even during continuous operation. Support for G.711 μ-law, G.711 A-law, MP3, and AAC audio formats further enhances compatibility with modern IP broadcasting systems.
Reliable Protection and Stable Operation:
The Hikvision amplifier incorporates multiple hardware protection mechanisms to ensure dependable long-term performance. Built-in safeguards include short-circuit protection, overcurrent protection, over-temperature protection, anti-static protection, surge protection, and electrical shock protection. These features help protect both the amplifier and connected speakers from unexpected electrical faults while improving operational reliability in demanding installations.
User-Friendly Front Panel Design:
Operation is simple thanks to the intuitive front panel controls. Separate knobs allow independent adjustment of total volume, microphone inputs, RCA inputs, bass, treble, and each output channel. LED indicators provide instant status monitoring for power, Bluetooth mode, USB playback, microphone activity, emergency alarm status, overload, clipping, and signal presence, allowing technicians to monitor system performance quickly.
Flexible Storage and Connectivity:
The amplifier includes 4GB built-in eMMC storage, with 1GB dedicated to audio file storage, enabling playback even without external media. A USB 2.0 port supports FAT32 and exFAT storage devices up to 256GB, while Bluetooth 5.0 provides wireless streaming within a range of approximately 10 meters. Gigabit Ethernet connectivity ensures stable communication across modern IP networks.
Ideal for Professional Public Address Systems:
With its high output power, advanced networking capabilities, multiple audio inputs, intelligent scheduling, and robust protection features, the Hikvision DS-QAZ1A500G1-VB2 is an excellent choice for professional public address and voice evacuation systems. It combines reliable persformance, flexible installation, and centralized management, making it suitable for organizations seeking a scalable and dependable IP audio broadcasting solution.
