A wireless PA system is a one-way receiver that receives transmissions from handheld 2-way radios or fixed base station intercoms, and then broadcasts them out over a loudspeaker. It can be used in both noisy or quiet environments.
The PA receiver receives transmissions from radios in a variety of frequencies: VHF, UHF, MURS, GRMS and FRS so it’s very flexible. The receivers can be field programmed to frequencies listed in the built-in frequency tables, or you can get a PC programming kit to program it to any frequency within its legal range. Or we can program them for you.
Business band VHF and UHF require an FCC license, however there is a set of VHF frequencies that do not. These are called MURS. There are 5 MURS channels that are license free.
There is also a wireless PA interface that enables you to use 2-way radios to broadcast to your existing wired PA system.
