The cornerstone of the PPA VP 37 system is the PPA T27 transmitter. It will broadcast a speaker’s voice, music program,or audio service wirelessly up to 500 feet to a listening audience. Audience participants use the PPA R37, R37-8, R38 or any wideband 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 front panel push-button channel selector. The speaker simply connects a microphone such as the MIC 100 into the 3.5 mm front panel jack to broadcast their voice. The T27 transmitter can also be used with up to five (5) daisy chained MIC049 conference microphones. This is particularly useful at large round table discussions where passing a microphone around would be impractical. Alternatively, the unit can be connected to a sound system through a line-level (RCA) jack to broadcast the audio service.
