When installing a wireless PA system, the single biggest expense is usually the wiring. Its not the cost of the wire, but rather the installation cost. As in the diagram below, there is often concrete or asphalt between locations where the public address system is to be installed. Trenching through that is both expensive and messy. The expense doesn’t stop once you get inside the building and you have to start running wires through walls too.
Going with a wireless PA system instead can save you money. The PA system consists of receiver unit with antenna that receives transmissions, amplifies them, and then sends them to an attached PA horn speaker. Up to two speakers can be attached to a single receiver. As shown in the diagram below, each zone can be set to different volume levels depending on the environment.
One benefit of a wireless PA system over a wired system is that you can use handheld two-way radios to make pages. So no matter where you are, you can page someone or make announcements. Even if you are up to two miles away!
One more benefit is that these units can also be programmed to receive transmissions from NOAA Weather Radio so employees will know instantly when bad weather is approaching.
