Hikvision 1000W 4-Zone Network Amplifier DS-QAZ1A1000G1-VB4

The DS-QAZ1A1000G1-VB4 is a 1000 W network amplifier with four zones — the head end of a large audio system rather than a component of a small one. At this size the buying decision has stopped being about the box and become about how the power is divided, because 1000 W across four zones is not 250 W each, and treating it as though it were is how a design runs out of amplifier in the largest space.

Being a network amplifier, it sits on the data network, which means the zones are addressed rather than hard-wired.

Where it fits

A site that needs this much power has areas that are genuinely different from one another: a warehouse or a production floor that swallows sound, a hall or an atrium with a lot of air to fill, and offices or corridors that need almost nothing. The power follows the space, not the fairness — the loading bay may take several times what the whole office floor does, and the design should say so explicitly rather than divide the total by the number of zones.

So the honest sequence is the same as on any audio job, just with more at stake: list the zones, count the points in each, total the load per zone, then check that the sum sits inside the amplifier’s budget with headroom left. Do it in that order and the amplifier is the last decision. Do it backwards and the amplifier becomes a constraint that shows up during commissioning, when changing it is expensive.

Before you order — three things to confirm

• The load per zone, not just the total. A design can fit the overall budget and still fail because one zone alone needs more than its share. Total each zone separately.
• The rack, the supply and the heat. A kilowatt-class amplifier belongs in a rack with real ventilation and a supply sized for it, and it should be on whatever protected power the rest of the head end uses. Confirm the cabinet exists and has room before delivery.
• The network and who runs it. This is a networked device on somebody’s infrastructure. Agree addressing, segregation and who supports it with the client’s IT before the order, not on the day.

Compatibility

It is a network device, so it is configured rather than rewired when zones change — which is the argument for this architecture on a building that will be re-partitioned or extended. The management platform and protocol support for the shipping firmware are confirmed on the datasheet before we quote. On a site with a smaller, fixed set of zones and no structured cabling already going in, the analogue multi-zone amplifier usually costs less to install, and we will tell you when that is the better answer.

What’s in the box

The amplifier and the manufacturer’s documentation. Speakers, cable, rack hardware, microphones, network switching and source equipment are separate line items — contents for the current revision are confirmed on your order.

Common questions

Is 1000 W more than we need?
Possibly, and that is worth checking rather than assuming either way. Send us the zone list with the point count and ratings; if a smaller amplifier covers it with headroom we will quote that instead.

Can we add zones later?
Zones on a network system are a configuration matter, but the number of outputs and the power are not. Tell us the two-year picture and we will size for it.

What happens to the audio if the network goes down?
That is a design question worth settling in writing before commissioning, and the behaviour for this model and firmware is confirmed on the datasheet. Ask us and we will put the answer in the quotation.
