B-CASTER
The »B-CASTER« Auracast™ streamers represent an innovation in audio streaming technology: Auracast™ broadcast audio allows wireless transmission to an unlimited number of Auracast™-enabled receivers. These include hearing aids, cochlear implants (CI) or headphones. People with hearing loss can experience significantly greater speech intelligibility and sound depth with Auracast™.
The streamers are characterised by reliable, stable audio delivery over long distances. They can be easily and conveniently integrated into a wide variety of environments and applications. Typical areas of application include conference rooms, theatres and other cultural venues, cinemas, educational institutions, and transport applications such as airports, railway stations, trains, and more.
All »B-CASTER« models, available with either a white or black housing, can be operated independently in plug-and-play mode.
The „CASTER-S license“ is available as an add-on for B-Caster models. Among other things, the use of models with a »CASTER-S license« enables the implementation of streaming structures in hybrid mode with the »B-SHOW« Wi-Fi streaming server (Wi-Fi streaming product group). Hybrid operation ensures compatibility with modern and many classic hearing aids.
