One of the problems with a wired PA (public address) system is that people who are mobile have no way to access it. With a wireless PA system interface device now people on two way radios or wireless intercom base stations can make pages over a wired public address system.
The Two Way Radio Wireless PA Interface receives transmissions from two way radios and then broadcasts those transmissions over a wired PA system. Now people can even be outside the building on a campus or property and still make announcements. This is an especially useful feature in emergency situations.
The Wireless PA Interface connects to the PA system either via RCA Phono Cables if it is located within six feet of the wireless PA system, or via the 600 ohm balanced MIC input on the PA system if it is further. A typical balanced cable contains two identical wires, which are twisted together and then wrapped with a third conductor (foil or braid) that acts as a shield.
The Wireless PA Interface will block out any signals that it receives that are not programmed with one of the selective signaling formats it uses. It can be paged with 2-way radios programmed for Quiet Call (CTCSS), Digital Quiet Call (DCS), 2-Tone Paging, or Selcall paging formats. Each format offers a unique method of paging the receiver and they ensure that not just anyone can use your PA system.
