| Overview |
The Williams
FM 558-12 PRO D is an FM Plus Large-area Dual FM and Wi-Fi
assistive listening system with Dante Input and 12 FM R38
receivers. It features Dante input, 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
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 Dante interface provides integrators with a
fully digital audio networking solution. It is based on
the Audinate UXT Ultimo chipset. This chipset supports
both AES67 and SMPTE 2110. Dante’s Ultimo UXT support of
AES67 and SMPTE 2110 allows integrators multiple audio
options to chose from for greater interoperability with
other audio equipment with their system design. This
allows the FM Plus Dante to be controlled by the Dante
Controller - the easy-to-use software from Audinate for
setting up and managing audio routing of Dante-enabled
products on an audio network
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
