Williams Sound FM Transmitters

  • There are 2 types of FM Transmitter. We call them Portable Transmitters and Table-Top Transmitters.
  • Portable transmitters are also called Body-Pack, Whisper or Tourguide Transmitters.
  • Portable transmitters are mostly used for Tourguide and Translation purposes. Table-Top Transmitters are used for Assisted Listening or Translation.
  • For Translation or Tourguide use, you will need to add a microphone. For Assisted Listening, you generally will not need a mic.
  • You will need to buy receivers to go with the transmitter.
  • A Transmitter can serve any number of Receivers, as long as they are within range.
  • Portable Transmitters have a range of about 150ft. Table-Top Transmitters have a range of up to 1000ft.
  • Some Williams Sound Table-Top Transmitters now include the ability to transmit to smartphones over your wi-fi system!
  • Williams Sound transmitters are covered by a limited lifetime warranty. Microphones and other accessories are warrantied for 90 days.


All the equipment we sell is FCC approved for translation and assistive listening in the USA. Please call us if you need equipment that can be used overseas.
