The Listen Technologies Auri TX2N-D is a two-channel Auracast assistive listening transmitter in white, mounted on a wall or ceiling like a Wi-Fi access point. It broadcasts Bluetooth LE Audio that compatible phones, earbuds and hearing aids can receive directly, with Auri RX1 receivers available for guests without an Auracast device. This version adds Dante network audio. Typical uses are theatres, lecture halls, places of worship, council chambers, meeting rooms and conference venues.
