Communicate your message without sacrificing security or sound quality. Infrared listening technology from Williams Sound ensures peace of mind, every time. From courtrooms to conferences, from retrofit to new construction, Williams Sound has complete, turnkey solutions to meet your facility’s needs for hearing assistance, simultaneous interpretation, audio description or secure listening services.
These wireless systems utilize infrared light to carry audio to individuals needing auditory assistance or language interpretation to overcome background noise, reverberation and distance from the sound source. Individuals use personal infrared receivers anywhere within the coverage area to hear crystal-clear sound directly from the sound source.
WaveCAST is a Wi-Fi platform designed for pro-audio applications where high-quality sound is required for streaming audio in real-time to smartphones and tablets. It is built on a hardware-based DSP audio system architecture, allowing system optimization to achieve the highest quality experience for the particular audio stream being delivered. Hearing assistance can be optimized for hearing loss, music can be optimized for high-fidelity playback, and voice can be set for maximum speech intelligibility. Custom presets can also be established for specific performance applications.
Professional audio inputs on the WaveCAST include 1/4” / XLR, phantom power and a line level output jack. In
addition to multi-stage gain control inputs, the DSP features include AGC, limiters, high and low pass filter, and adjustable range compressor control. The 16-bit DAC provides a 48Khz sample rate for a smooth digital stream and minimizes digital harshness. WaveCAST supports both unicast and multicast network configurations. Up to four
WaveCAST systems can be connected to the same Wi-Fi network to provide multiple listening channels — supporting up to 45 users in unicast mode or up to 1,500+ users in multicast mode.
The free WaveCAST listening app provides an easy-to-use, intuitive user interface and is available in iOS or Android. Listeners easily select channel and volume level once their personal device is connected to the Wi-Fi network.
WaveCAST Dante is the first Wi-Fi assistive listening system with Dante control. The WaveCAST Dante interface is based on the Audinate UXT Ultimo chipset. This chipset supports both AES67 and SMPTE 2110.
Ideal for use in: performance venues, houses of worship, public transportation terminals, education, gaming and fitness centers
Williams Sound is ready to revolutionize the world of assistive listening with the introduction of FM+ — the industry’s first dual-transmission system able to broadcast both FM and Wi-Fi audio from a single device.
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+, the customer gets both for little more than the cost of an FM-only solution.
The FM+ 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 own smartphone or tablet (via the free WaveCAST Listening app). With this flexibility comes exceptional audio quality, as the FM+ is built on a professional digital audio (DSP) platform. Added plus: Its optional Dante interface provides integrators with a full digital audio networking solution.
FM+ is designed for 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. FM+ supports both the new iOS and Android WaveCAST listening apps — in addition to all current and legacy Williams Sound FM receivers operating on the 72-76 MHz bandwidth.
FM+ Dante is the first FM / Wi-Fi assistive listening system with Dante control. The FM+ Dante interface provides integrators with a full digital audio networking solution. It is based on the Audinate UXT Ultimo chipset. This chipset supports both AES67 and SMPTE 2110.
