Opus AuraGate transmitter

General Description

The Opus AuraGate is an innovative Auracast™  broadcast transmitter designed to deliver a high-quality audio experience to compatible hearing aids, headphones, cochlear implants or dedicated receivers.

Auracast™ is a new standard for Bluetooth Low Energy audio transmission which enables one-to-many sharing of audio.

The two channel AuraGate terminal has a selection of audio inputs available. These include microphone level (with switchable phantom power), line level, 100v line loudspeaker level, SPDIF optical and USB-C.

System configuration is quick and easy via the intuitive AuraConnect app (Android and iOS available). The broadcast name, audio quality, range and, if required, access code can all be programmed. The code can then either be shared or a QR code can be generated.

The versatile bracket enables the AuraGate to be easily wall or ceiling mounted.

Auracast™ enables crowded public spaces to offer clear audio in concerts halls, theatres, universities, exhibitions spaces, stadiums, silent screens in gymnasiums, sport bars, airport lounges, waiting rooms, museums, music festivals and many other places where multi-channel BYOD (Bring Your Own Device) audio streaming is required.
