The PPA-T27 is a compact base station transmitter with ANT 021 Antenna, Ch. E, Tunes A-T. The PPA T27 transmitter will broadcast a speaker’s voice, music program, or audio service wirelessly up to 500 feet to a listening audience. Audience participants use the optional R35, R35-8, or any FM receiver operating on 72-76 MHz frequency to pick up the broadcast.

The PPA T27 has 17 available frequencies and features an LED display and push-button channel selector. The speaker simply connects a microphone with a 3.5mm plug into the unit to broadcast their voice. Alternatively, the unit can connect to a sound system through a line-level (RCA) jack to broadcast music or other audio service.
