The PPA T46 transmitter will broadcast a speaker’s voice or audio program on one of 17 available channels, 72-76 MHz, to listeners using PPA R38 or PPA R37 receivers. The unit features flexible microphone and auxiliary input jacks, push-button on/off/mute controls, channel lock and selectable compression. The T46 has the ability to operate in dual channel mode, allowing the user to easily switch between two different transmitting channels, each with its own set up parameters. An OLED screen displays current operating status and menu information. The PPA T46 operates up to 30 hours on two (2) AA Alkaline batteries, and up to 20 hours with two (2) NiMH batteries. It has recharge capability when used with Williams Sound drop-in chargers. Lightweight and portable, the PPA T46 will operate at a range of up to 150 feet (46m) from the listening audience. Ideal for providing hearing assistance to students in the classroom, tour group participants, employee training, business meetings and more.
Note: The Personal PA® system is approved by the FCC for operation in U.S. markets. The Personal PA® cannot be used in all countries. Check with your government´s radio regulations for 72 – 76 MHz operation.

The PPA T46 is FCC Part 15 compliant.
Effective July 11, 2016, the FCC has mandated tighter emissions limits on auditory assistance transmitters (72-76 MHz) manufactured or imported after this date to help avoid interference with and/or degradation of other airborne signals (All products manufactured prior to July 11, 2016, are compliant). Williams Sound FM transmitters – PPA T46, PPA T27 and PPA T45 (all models) – all have received a Grant of Certification from the FCC and are fully compliant/approved under this new mandate.
