The PPA T27 is a compact FM transmitter that broadcasts a speaker’s voice, music program or other audio wirelessly up to 1000 feet to a listening audience. The speaker simply connects a microphone with a 3.5mm plug into the unit to broadcast their voice. The PPA T27 compact FM transmitter also can connect to a sound system through a line-level (RCA) jack to broadcast music or other audio service. Audience participants can use an optional R37, R38 or any FM receiver operating on the 72-76 MHz frequency to pick up the broadcast.
