    FM T55 - Overview

    The WILLIAMS AV FM T55 Plus integrates professional WaveCAST Wi-Fi audio server technology into a Williams Sound FM assistive listening system. End users can now listen with either an FM receiver or with their own smartphone (via the WaveCAST Listening App). Along with this flexibility comes exceptional audio quality, as the FM Plus is built on a professional digital audio (DSP) platform. Added plus: Its optional Dante interface provides integrators with a full audio networking solution.

    The FM Plus is designed to support those who want to use their own smartphones and headphones for a more discreet assistive listening experience. Simplicity is also available for those who want a more traditional assistive listening system with a dedicated FM receiver and headset. Venues no longer need to choose between providing FM or Wi-Fi assistive listening systems. FM Plus supports both the new iOS and Android WaveCAST Apps -- in addition to all of the current and legacy Williams Sound FM receivers operating on the 72-76 MHz bandwidth.

    The FM Plus can have most settings changed via the front panel interface, or the hosted web interface.
    A remote programming guide is available upon request.

    This version is not Dante compatible. For Dante compatibility, see the FM T55 D.

    The FM Plus uses the WaveCAST app to provide an easy-to-use, intuitive user interface. It is available in iOS or Android. Listeners easily select channel and volume level once their personal device is connected to the Wi-Fi network. The app does not work on FM Broadcasts.

    Note: The FM + connects to the installation location's Wi-Fi Network. It does not provide a network on its own. The Wi-Fi network will need to be installed and established before the FM + can be used.
