An FM system consists of 2 parts:
1. The Transmitter and Microphone. The transmitter and microphone are worn by the teacher or parent. This portion of the FM System picks up the voice from the microphone and transmits it to the childs ears. There are two different types of microphones available. The first is the lapel microphone which is clipped to the shirt, approximately 6 inches from the mouth. The second type is the boom microphone which is worn approximately 3 inches from the mouth. The transmitter also comes with audio cable to enable connection to audio devices such as a television, CD player, MP3 player, or computer.
2. The Receiver. The receivers are attached to the hearing aids and receive the sound from the transmitter and deliver it to the hearing aids. The receivers are small, lightweight and easy to use. Receivers are also available for children or adults who do not wear hearing aids such as the Phonak Edulink.
