The PPA T27 compact base station transmitter will broadcast a speaker's voice, music program or audio service wirelessly up to 500 feet to a listening audience. It is designed for hearing assistance in places of public access to help overcome background noise, reverberation or distance from the sound source. Use it with a microphone as a stand-alone system, or integrate it with your existing sound system.

Audience participants can use an optional FM receiver operating on 72-76 MHz frequency to pick up the broadcast (FM receiver not included). 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 to audience listeners up to 500 feet away. Alternatively, the unit can connect to a sound system through a line-level (RCA) jack to broadcast music or other audio service. Five year warranty.
