With the FM 557 Plus Large Area Dual FM and Wi-Fi Assistive Listening System, you can experience the perfect blend of cutting-edge technology and exceptional audio quality. This system integrates the professional WaveCAST Wi-Fi audio server technology into a Williams Sound FM assistive listening system, offering users the flexibility to listen with either an FM receiver or their own smartphone via the WaveCAST Listening App.
The FM T55 Transmitter, a key component of this system, is built on a professional digital audio (DSP) platform, ensuring superior sound quality. Its optional Dante interface offers a comprehensive audio networking solution for integrators. This transmitter is designed to cater to those who prefer using their own smartphones and headphones for a more discreet listening experience, as well as those who favor a traditional assistive listening system with a dedicated FM receiver and headset.
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. Users can easily adjust settings via the front panel interface or the hosted web interface. The WaveCAST app, available in iOS or Android, provides an intuitive user interface, allowing listeners to easily select the channel and volume level once their device is connected to the Wi-Fi network.
The package also includes 12 PPA R37N Receivers, which feature easy-to-use, seek-button channel selection with access to 17 pre-set wideband frequencies between 72-76 MHz. These receivers are compatible with various Williams Sound transmitters and offer digitally synthesized audio for enhanced clarity and stability. A versatile 3.5mm stereo/mono jack allows for a variety of earphone and headphone options, and is neckloop/telecoil-equipped-hearing-aid compatible.
The 12 EAR 022 Surround Earphones included in the system offer excellent sound quality and can be used with all Williams Sound receivers and Pocketalkers. These around-ear speaker earphones are rigorously tested and approved for quality, reliability, and compatibility with Williams Sound systems.
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 features an integrated safety breakaway device for user safety.
Finally, the package includes an IDP 008 ADA Wall Plaque, a self-adhesive wall plaque that informs patrons of the availability of a hearing assistance system in your establishment. Ideal for theaters, auditoriums, and more, this plaque is large, easy-to-see, and a testament to your commitment to accessibility.
