| Overview |
Williams Sound
is ready to revolutionize the world of assistive listening
with the introduction of FM Plus Dante, the industry's
first dual-transmission system able to broadcast both FM
and Wi-Fi audio from a single device. It is also the first
with a Dante audio input
Often, the integrator's most difficult choice when
designing an assistive listening system is deciding
between an FM or Wi-Fi solution for their customer. With
FM Plus Dante, the customer gets both for little more than
the cost of an FM-only solution. The FM Plus Dante
integrates the new 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). With
this flexibility comes exceptional audio quality, as the
FM Plus Dante is built on a professional digital audio
(DSP) platform
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 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
FM Plus Dante is designed for 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. FM Plus
supports both the new iOS and Android WaveCAST Apps, in
addition to all current and legacy Williams Sound FM
receivers operating on the 72-76 MHz bandwidth |
