Auri Auracast™ Assistive Listening System
Auri is a professional installed assistive listening system using Auracast™ broadcast audio. It can serve an unlimited number of compatible receiving devices while venues can also provide dedicated Auri RX1 receivers for users who need them.
Direct answers
What Auri and Auracast mean for assistive listening.
Auracast™ is based on Bluetooth® Low Energy Audio and lets one broadcast reach many compatible receivers. Auri turns that capability into an installed Pro AV assistive-listening system with venue transmitters, dedicated receivers, docks and network management.
What is Auri?
A complete professional assistive-listening system powered by Ampetronic and Listen Technologies, designed for permanent venue installation and managed broadcast audio.
Can visitors use their own device?
Yes, when the personal device is compatible with the Auracast broadcast being provided. Venues can also issue Auri RX1 receivers so access does not depend on every visitor owning a compatible device.
Can broadcasts be private?
Auri supports open or encrypted broadcasts. Channel selection and system settings can be managed for the venue application.
How Auri works
Audio source → transmitter → listener.
Connect the audio source
Feed programme, microphone or system audio to the Auri transmitter.
Broadcast the audio
The installed transmitter sends one or two Auracast broadcasts, with mono, stereo or dual-mono routing options depending on the design.
Listen on a compatible receiver
Users select the broadcast on an Auri RX1 receiver or another compatible Auracast personal device.
System components
One installed platform, four practical building blocks.
System quantity depends on coverage, channel count, receiver provision and charging requirements. Multiple transmitters can be used to add channels or extend coverage.

Applications
Designed for public, education and professional spaces.
The brochure positions Auri for classrooms, lecture halls, boardrooms, houses of worship, performing arts centres and other venues where clear accessible audio is needed.
Auri Manager
Network configuration for one room or many locations.
Auri Manager for Windows supports discovery, configuration, control and software updates for network-attached transmitters, charging docks and docked receivers.
- Manage channel names and settings.
- Group transmitters for larger deployments.
- Password-protect audio channels.
- Download and install firmware updates.
Hybrid accessibility
Auri can complement an existing hearing-loop strategy.
The brochure states that Auri can be retrofitted into existing venues or combined with other assistive-listening technologies, including Ampetronic hearing loops. A transmitter line output can also feed a second assistive-listening system. PNSS can therefore assess Auracast, induction loop or a combined architecture based on users, venue coverage and project requirements.

Final Malaysia configuration, stock, approvals, receiver quantities and accessibility requirements should be confirmed for each project.
