B-SHOW

Bettear B-SHOW - Wi-Fi audio streaming server for hearing assistance, compatible with Auracast, up to 1000 users (multicast)

Clear, understandable sound delivered straight to the listener. Bettear B-SHOW is a professional low-latency Wi-Fi audio streaming server designed for personalized listening and event accessibility for people with hearing impairments. The device transmits sound directly to hearing aids, cochlear implants, or headphones. One B-SHOW supports up to 1000 users in multicast mode or up to 100 in unicast mode. The system can be expanded with additional Wi-Fi access points. In addition to audio, B-SHOW provides listeners with dynamic visual and textual content, including live transcription and multilingual subtitles, created in real-time by a human or prepared in advance. This solution is for AV integrators who equip theaters, cinemas, concert halls, and classrooms.

B-SHOW works with the Bettear Auracast™ ecosystem and supports hybrid deployments combining Wi-Fi and Auracast™, allowing for full coverage of the venue. The audio signal can be fed through two combo XLR/TRS inputs or terminal blocks, and the built-in DSP processing with automatic gain control (AGC) and low- and high-pass filters ensures clarity of the message. The device can be managed locally or in the cloud, and the included 1U rack adapter facilitates installation in a cabinet.
