These systems deliver audio directly to a person’s ear through an earphone. This earphone can be used in conjunction with a hearing aid or placed directly on the ear. The earphone is connected to a receiver, which picks up a broadcast transmission of an audio source. Volume can be adjusted by the user. Audio originates from a person speaking into a microphone or sound system. Assistive Listening Devices are commonly available in facilities such as places of worship, stadiums, arenas, meeting rooms, schools, etc. In various public facilities in the U.S.A., assistive listening device accessibility is mandated by the Americans with Disabilities Act, and must be provided by the facility for the hard of hearing. Listen’s FM Assistive Listening Systems, in particular, are extremely versatile, durable and easy to set up and use. 100% compatible with all major manufacturers of FM assistive listening products, Listen products offer access to 57 channels at 72MHz or at 216MHz. This means that if you have a Listen receiver and walk into a facility, simply press “SEEK” to find the transmitting channel. 57 channels also more likely guarantee that a facility manager can find a clear transmission channel to broadcast on or can easily change channels if interference becomes a problem. Also, Listen’s receivers and portable transmitter feature high performance NiMH batteries which allow for hassle- free, long battery life. Another unique feature is Listen’s LCD Display, which communicates battery level, channel and RF signal strength. Listen is dedicated to whatever-it-takes customer support. We even offer a Limited Lifetime Warranty that assures maximum performance and no hassle. Contact Listen; we’ll be happy to assist you.
