The Two-Way Radio Wireless PA Bridge receiver allows someone on a two-way radio or base station intercom to send an announcement to all the wired speakers in a PA/Intercom system. The Wireless PA Interface receiver can be connected to an existing wired system and it can receive transmissions from up to a mile away. Radio range can be extended with the use of an external antenna.
The Wireless PA Bridge 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.
The Wireless PA Interface connects to the Aux Input of the PA system via RCA Phono Cable if it is located within six feet of the wireless PA system. Or it connects via the 600 ohm balanced MIC input on the PA system the distance it is further than 6 feet. 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.
