Overview
The Williams FM 558-12 PRO is an FM Plus Large-area Dual FM and Wi-Fi assistive listening system with 12 FM R38 receivers. It features coaxial cable and rack panel kit for professional installation. The new FM 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 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 new FM Plus is designed to support those who want to use their 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. The 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. The FM Plus uses the WaveCAST app to provide an easy-to-use, intuitive user interface. It is available on iOS or Android. Listeners easily select channel and volume level once their device is connected to the Wi-Fi network. The app does not work on FM Broadcasts
