What does the DS-QAZ1A500G1-VB2 do?

The DS-QAZ1A500G1-VB2 is a 500W 2-zone network amplifier designed for public address systems. It distributes audio across 2 separate speaker zones and supports scheduled broadcast, live broadcast and emergency broadcast through a compatible network PA platform, making it useful for planned announcements, real-time paging and urgent alert messaging.

How much total power does this amplifier provide?

The rated output is 500W total. When planning the installation, the combined speaker wattage across both zones must not exceed this figure. Speaker impedance, cable length and zone load distribution should all be checked by a qualified installer before connecting speakers to the amplifier.

How many audio zones does the DS-QAZ1A500G1-VB2 support?

It supports 2 audio output zones. Each zone can be managed independently within a compatible network PA system, allowing different areas of a site to receive separate announcements or be addressed individually depending on broadcast mode and system configuration.

What types of speakers can be connected?

The amplifier is compatible with public address speaker types commonly used in commercial installations, including ceiling speakers, cabinet speakers, pendant speakers and horn speakers, subject to the speaker line design and wattage requirements of the specific site. Total speaker load across both zones must be calculated before connection.

Can scheduled announcements be automated without manual operation?

Yes. Scheduled broadcast support allows timed announcements to play automatically at set times within the compatible PA system. This is useful for recurring messages such as school bells, shift change alerts, routine safety reminders and daily operational broadcasts that need to run consistently without staff intervention each time.

Is the emergency broadcast function separate from scheduled and live broadcast?

Yes. Emergency broadcast is a distinct mode that supports urgent message delivery through the compatible PA system. It is designed for scenarios such as evacuation alerts and incident notifications where immediate audio output is required across connected zones. How emergency broadcast priority behaves in relation to other broadcast modes will depend on the wider system configuration and should be planned before installation.

What is the lead time for this product and how does it affect ordering?

A 70-day lead time applies to the DS-QAZ1A500G1-VB2. For projects supplied through Security Wholesalers, this amplifier should be ordered well in advance of the intended installation date. Confirming availability and factoring the lead time into the project schedule early will help avoid delays to system commissioning.

Description

Product Overview

For commercial and institutional PA installations requiring powerful zone-based audio distribution, the Hikvision DS-QAZ1A500G1-VB2 provides a 500W 2-zone network amplifier with scheduled, live and emergency broadcast capability in a single unit. Equipped with network amplifier architecture, it integrates into compatible public address systems for centralised audio control across 2 separate speaker zones. It also supports all three core broadcast modes: scheduled messages for routine timed announcements, live broadcast for real-time paging, and emergency broadcast for urgent site notifications. This makes it well suited to schools, warehouses, retail centres, offices, transport facilities, hospitality venues and multi-area commercial buildings where organised zone audio management is required. Please note a 70-day lead time applies to this product and should be factored into project planning before ordering.

Key Capabilities

500W Amplifier Output

With 500W total rated power, the DS-QAZ1A500G1-VB2 supports medium-to-large speaker layouts across a compatible public address system, providing strong audio output for sites where broad coverage across multiple areas is required.

2-Zone Audio Control

Two-zone output control allows the system to direct audio to separate building areas independently, giving operators the ability to manage announcements for different spaces without broadcasting across the entire site.

Scheduled Broadcast

Scheduled broadcast support allows timed messages to play automatically, which is practical for school bell systems, shift change alerts, recurring staff reminders and any routine announcement that runs on a fixed daily or weekly cycle.

Live Broadcast

Live broadcast enables real-time voice announcements from a connected operator position, supporting reception paging, control room communication, retail counter messages and site management workflows as they occur.

Emergency Broadcast

Emergency broadcast functionality allows urgent notifications to be pushed through compatible PA workflows, supporting evacuation messaging, incident alerts and safety announcements that need immediate delivery across connected speaker zones.

Best For

2-Zone Network PA Installations: Suited to sites where two distinct speaker areas need independent audio control through a compatible network public address system.
Schools and Education Campuses: The scheduled broadcast function supports bell-style timing, timed reminders and routine daily announcements without manual intervention.
Warehouses and Industrial Sites: Live broadcast and emergency broadcast together support both daily operational communication and urgent safety notifications across large work areas.
Retail Centres and Commercial Buildings: Suitable for customer announcements, staff paging and emergency messaging managed from a centralised network PA platform.

Why Choose the DS-QAZ1A500G1-VB2

The DS-QAZ1A500G1-VB2 brings together three broadcast modes and 2-zone output control in a single 500W network amplifier, which separates it from simpler amplifiers that support only live paging or fixed-output analogue designs. The 500W capacity makes it a practical choice for medium-to-large speaker deployments where a lower-power amplifier would fall short, and the network integration allows the unit to participate in centralised PA system management rather than operating in isolation. The combination of scheduled, live and emergency broadcast in one unit reduces the need for additional broadcast controllers in compatible system designs. Available through Security Wholesalers, the DS-QAZ1A500G1-VB2 should be specified after confirming speaker load, zone wiring, amplifier ventilation, rack space, network compatibility and broadcast workflow requirements. A 70-day lead time applies, so early project planning is essential.

Buyer Decision Tips

Zone and Power Planning: Before ordering, calculate the total speaker wattage across both zones and confirm it does not exceed the 500W rated output. Unbalanced zone loads or undersized speaker cable can affect performance. If the installation requires more than 2 zones, a different amplifier model with additional zone outputs will be needed.

Lead Time Consideration: This product carries a 70-day lead time. For projects with a fixed completion date, the DS-QAZ1A500G1-VB2 should be ordered well ahead of the scheduled installation date. Confirm stock availability and project timelines before committing to a site commencement date.
