CASTER

Bettear CASTER - professional Auracast transmitter, black

Bettear CASTER is a professional Auracast™ transmitter that samples analogue audio and broadcasts it live - for assistive listening in venues and for high-quality streaming to personal devices. Two balanced analogue inputs reach Auracast™-enabled hearing aids, cochlear implants and earbuds, as well as Bettear RTX receivers. Latency stays below 40ms, and the broadcast can be secured with AES128 encryption.

The transmitter carries one stereo programme or two independent mono programmes, while DSP processing (AGC plus high-pass and low-pass filters) keeps speech clear. PoE+ delivers power and network over a single cable, and the whole system is managed from the built-in web panel or the Hive Central platform. CASTER is a fit for theatres, cinemas, classrooms, meeting rooms, museums, courtrooms, places of worship, transport hubs and sports arenas.
