The Americans with Disabilities Act (ADA) requires public facilities to provide equal access to people with disabilities, including those who are hard-of-hearing. The Williams Sound FM ADA Kit 1 is a convenient and economical solution for satisfying these requirements. This kit provides everything you need to accommodate individuals for hearing accessibility in large venues such as auditoriums, theaters, conferences and houses of worship. The PPA T27 transmitter broadcasts a speakers voice, music program or audio source wirelessly up to 1000 feet to a listening audience.
