Receiver with on/off/volume control. High level of sensitivity allows audience members to sit wherever they choose, even in large auditoriums or stadiums. Small, elegant design enables the listener to focus on the content of the presentation, not the assistive listening device. The attractive design is accentuated by its ease of use. Especially useful for the elderly or those with physical disabilities. The receiver is tunable to any FCC approved assistive listening channel, allowing you to stock only one type of receiver instead of separate receivers for each channel. Gentner also provides a variety of accessories for the receiver that can be used with or without a hearing aid.
