For a comprehensive and advanced assistive listening solution, look no further than the FM 557 Pro Plus Large Area Dual FM & Wi-Fi Assistive Listening System. This high-quality system integrates the professional WaveCAST Wi-Fi audio server technology into a Williams Sound FM assistive listening system, offering exceptional audio quality built on a professional digital audio (DSP) platform. The FM T55 Transmitter, a key component of this system, provides flexibility for end users to listen with either an FM receiver or their own smartphone via the WaveCAST Listening App. This innovative feature supports those who prefer a more discreet assistive listening experience using their own devices. The FM Plus supports both iOS and Android WaveCAST Apps, in addition to all current and legacy Williams Sound FM receivers operating on the 72-76 MHz bandwidth. The system includes 24 PPA R37N Receivers, offering easy-to-use, seek-button channel selection with access to 17 pre-set wideband frequencies between 72-76 MHz. These receivers are compatible with a range of Williams Sound transmitters and are digitally synthesized for enhanced audio clarity and stability. The package also includes 24 EAR 022 Surround Earphones, designed for excellent sound quality and compatibility with all Williams Sound receivers and Pocketalkers. These around-ear speaker earphones hang on the outside of the ear, providing a comfortable listening experience. The NKL 001 Neckloop is designed to magnetically couple the audio output from a Williams Sound unit into a hearing aid equipped with a T-Coil, providing an additional listening option for those with hearing aids. The system also comes with a CHG 3512 12-Bay Charger, a multi-unit, drop-in style charger that can conveniently store and charge up to 12 Williams AV receivers or transmitters over a 16-hour time span. The ANT 005 Remote Coaxial Antenna, with a 22' overall cable length and an active antenna of the last 80 inches, is designed for use with large-area FM transmitters. The package also includes an IDP 008 ADA Wall Plaque, a self-adhesive wall plaque that alerts patrons to the availability of a hearing assistance system, and a RPK 005 Rack Panel Kit for mounting one transmitter or modulator. In summary, the FM 557 Pro Plus Large Area Dual FM & Wi-Fi Assistive Listening System offers a durable, comprehensive, and innovative solution for assistive listening in large areas such as auditoriums, lecture halls, and other public spaces.
