Bettear B-CASTER-X Auracast Transmitter with Analog Input - White

The CASTER X is a professional Auracast™ streamer with a switchable internal or external antenna, so RF coverage can be tuned to the room rather than the other way round.

It takes two balanced analog inputs and broadcasts to Auracast™-enabled hearing aids, cochlear  implants and earbuds, plus RTX receivers. Managed from the built-in web panel or Hive Central.

Built for real-world deployments, it enables crystal-clear high-quality, low-latency audio broadcasting to unlimited listeners - from theaters and classrooms to museums and transportation hubs.

Flexible by design, CASTER supports both open and secure broadcasts, making it suitable for everyday use as well as sensitive and confidential environments.

With PoE in and PoE out, it enables clean installations and seamless cascading of power, audio, and control over Ethernet - combined with centralized management via Hive Central.

 

Suitable for cinemas, museums, music venues, classrooms, courtrooms, sports arenas, airports, houses of worship, and more.

 

Seamless Network Expansion: Seamlessly expand your Auracast™ network to cover larger distance or to increase audio stream capacity over a single Ethernet connection.
