Experience the seamless integration of professional audio technology with the FM 557 Pro Plus Large Area Dual FM & Wi-Fi Assistive Listening System. This advanced system includes the FM T55 Transmitter, which combines the power of a professional WaveCAST Wi-Fi audio server with the convenience of a Williams Sound FM assistive listening system. This allows users to listen via an FM receiver or their own smartphone using the WaveCAST Listening App, offering exceptional flexibility and audio quality. The FM Plus is built on a professional digital audio (DSP) platform, ensuring superior sound quality. It 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. This system is designed to cater to those who prefer using their own smartphones and headphones for a discreet listening experience, as well as those who favor a traditional assistive listening system with a dedicated FM receiver and headset. The system also includes four 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 four EAR 022 Surround Earphones, designed to hang on the outside of the ear for excellent sound quality. These earphones are compatible with all Williams Sound receivers and Pocketalkers and have been rigorously tested for quality, reliability, and compatibility. 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. It also works with any audio device which has an 8-16 Ohm audio output through a 3.5mm jack. The CHG 3502 Body-Pack Charger is designed for charging and storing up to two Williams Sound T36, T46, R37, and Motiva products. 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 an RPK 005 Rack Panel Kit for mounting one transmitter or modulator. The FM 557 Pro Plus Large Area Dual FM & Wi-Fi Assistive Listening System is a comprehensive solution for superior audio quality and flexible listening options.
