The Listen Technologies Auri 2 Channel Transmitter transforms accessibility infrastructure for houses of worship, performing arts centers, conference facilities, and municipal venues requiring ADA-compliant assistive listening. Its dual-radio architecture enables simultaneous broadcast of two independent Auracast streams, each fed by balanced analog mic or line sources, optional Dante inputs, or Audio over IP from other networked transmitters. Built-in AGC and selectable sample rates ensure intelligible speech reproduction across mono and stereo formats. Repeater mode extends coverage into large or acoustically challenging spaces without additional cabling.

Integrators gain streamlined deployment through single-cable PoE connectivity that delivers power, control, and network audio over one Cat6 run. The low-profile enclosure mounts to standard electrical back boxes or VESA 75 patterns, blending into architectural environments while providing secure AES128-CCM encrypted broadcasts. Web-based Auri Manager software centralizes configuration and monitoring across distributed installations, eliminating the need for on-site adjustments after commissioning. Switchable phantom power and loop-through line outputs accommodate microphone systems and downstream mixers within a single rack-free workflow.
