The Williams Sound FM 558 FM+ Assistive Listening System Package offers a complete turnkey solution. It includes 4 PPA R38 receivers with earphones and neckloops, and an FM T55 transmitter for both FM and Wi-Fi transmission from the same box.
This system features the cutting-edge PPA T55 transmitter (replacing the T45 FM transmitter) with multiple digital audio input options and an OLED display with easy-to manage navigation and network control features.
The PPA R38 is a multi-channel FM receiver with a high-resolution OLED screen. Each receiver comes with earphones and batteries. The R38 offers a quick view of receiver status and immediate entry to all user settings. On-screen channel selection offers easy access to 17 preset, wide-band frequencies (72 to 76 MHz). The system is expandable, accommodating any number of listeners. This system complies with 2010 ADA guidelines for hearing assistance.
The FM+ Assistive Listening System from Williams Sound integrates professional WaveCAST Wi-Fi audio server technology, allowing end users to listen with either an FM receiver or with their own smartphone (via the WaveCAST Audio Receiver app). Along with this flexibility comes exceptional audio quality, as the FM+ is built on a professional digital audio (DSP) platform.
The FM+ 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+ supports both the new iOS and Android WaveCAST Audio Receiver apps in addition to all of the current and legacy Williams Sound FM receivers operating on the 72-76 MHz bandwidth.
Most settings can be changed via the front panel interface, or over the hosted web interface. A remote programming guide is available upon request. The FM+ uses the WaveCAST app to provide an easy-to-use, intuitive user interface. You can easily select channels and volume level once your mobile device is connected to the Wi-Fi network. (The app does not work on FM broadcasts.)
