Listen Technologies AURI-RX1 – Auracast Assistive Listening Receiver

Product Overview

The Listen Technologies AURI-RX1 is an Auracast assistive listening receiver for venues deploying Bluetooth LE Audio broadcast rather than RF or infrared. It receives an Auri transmitter broadcast and feeds wired headphones or an inductive neck loop from either of two 3.5mm TRRS outputs. Over 20 hours of battery life on a field replaceable cell suits a venue that issues receivers across a full day of sessions. It is the hardware option for patrons who do not want to use their own phone with a commercial assistive listening system.

Product Description

Auracast is the broadcast profile within Bluetooth LE Audio, and it changes the shape of an assistive listening deployment: instead of a dedicated RF or IR distribution layer, the venue broadcasts and any compliant receiver joins.

The AURI-RX1 is Listen's dedicated receiver for that broadcast, running Bluetooth 5.3 in Auracast compliant, broadcast receive only mode with the LC3 codec and AES128-CCM encryption. Two 3.5mm TRRS connections let a listener choose headphones or a neck loop for telecoil-equipped hearing aids, with 16mW maximum output into 32Ω. Latency sits between 29 and 45 ms, low enough that lip sync holds in a room where the listener can see the talker.

An OLED display with automatic brightness handles channel and battery indication without a backlight that distracts in a darkened auditorium. The lithium polymer battery is field replaceable, which matters over a multi-year deployment where a sealed unit would become disposable. Charging runs from any USB-C PD compliant supply or from a docking station, so a venue can standardise on one charging method across its receiver fleet.

For fleet charging and storage, pair with the Auri Docking Station 4 or the Auri Docking Station 16. Single-unit charging uses the 1-port USB-C charger. Telecoil users need the Auri earphone and neck loop lanyard, and replacement lithium polymer batteries are stocked separately for fleet maintenance. Venues are required to signpost the service; the Auri assistive listening signage kit covers that.

Frequently Asked Questions

Does the AURI-RX1 work with any Auracast broadcast?
It operates in Auracast compliant, broadcast receive only mode, so it receives compliant broadcasts. Confirm the transmitter side of the design with your Listen representative before mixing manufacturers on a compliance-critical installation.

Can patrons use their own phones instead?
Auracast is designed so compliant consumer devices can receive the broadcast. The AURI-RX1 exists for patrons who do not have a compliant device, which is what an accessibility obligation generally requires the venue to provide.

How does it serve hearing aid users?
Through an inductive neck loop on either 3.5mm TRRS output, which couples to the telecoil in a hearing aid. The neck loop lanyard is ordered separately.

What is involved in charging a fleet?
Docking stations are available in 4-unit and 16-unit configurations for charging and storage. Single units charge from any USB-C PD compliant supply in under 4 hours from flat.

Is the battery replaceable?
Yes. The lithium polymer cell is field replaceable and stocked as a separate part, which keeps a receiver fleet serviceable rather than disposable.

How does latency affect a live event?
Latency is 29 to 45 ms. That is low enough for lip sync in a room where the listener can see the presenter, unlike Wi-Fi based systems which typically run higher.

What warranty and support apply?
Warranty duration and technical support terms are set by Listen Technologies. Contact Creation Networks for current terms, RMA handling and pre-sales design support.
