1. How do you use an Auracast receiver like the Infinium R1?

Users can listen to Auracast audio with headphones or earphones connected to the receiver via the 3.5 mm stereo jack, or through t-coil-equipped hearing aids using a compatible stereo neck loop connected to the receiver.

2. Can you use hearing aids with the Infinium R1 Auracast receiver?

Yes. The Infinium R1 works with t-coil-enabled hearing aids when used with a stereo neck loop connected to the receiver, providing a clear and accessible assistive listening experience.


3. What is the difference between open and secure audio on an Auracast receiver?

Open (public) audio allows anyone to access an Auracast broadcast, while secure (private) audio requires a PIN for access, enabling controlled or restricted listening.


4. How long does the Infinium R1 receiver battery last?

The Infinium R1 is designed for reliable, all-day operation on a single charge, supporting full-day events and continuous venue use.


5. How do you charge the Infinium R1 receiver?

The receiver can be charged using a standard USB connection or with an optional multi-unit charging dock for efficient charging and storage.


6. Does the Infinium R1 help meet ADA assistive listening requirements?

Yes. When used as part of a complete Infinium broadcast-audio system with receivers, the Infinium R1 supports ADA-compliant assistive listening, helping venues create a more inclusive experience.

7. Does the Infinium R1 receiver need to be AES67 compliant or connected to Dante Domain Manager (DDM)?


No. The Infinium R1 receiver connects to the system over Bluetooth® LE Auracast™, not the Dante network, so it doesn’t require AES67 compliance or DDM enrollment itself. AES67 compliance and Dante Domain Manager (DDM) management apply to the Infinium Controller and Transmitter, which handle the Dante audio network side of the system.
