Designed for venues requiring assistive listening solutions, this compact server broadcasts synchronized audio to up to 500 listeners simultaneously using existing Wi-Fi networks. Integrators benefit from flexible input options—both consumer RCA and professional terminal block connections—allowing seamless integration into installed sound systems without additional analog-to-digital conversion hardware.

The platform scales horizontally by adding multiple units to increase channel count and user capacity, while optional LA-490 beacons enable location-based automatic channel switching throughout multi-zone facilities. Public address override capability ensures emergency announcements reach all connected devices instantly, regardless of selected channel.

Central management through Windows-based software allows complete control over server configuration, receiver checkout tracking, and mobile app customization including venue branding, channel graphics, and promotional content. The system supports both BYOD smartphone implementations and dedicated LWR-1050 receivers for compliance-mandated applications where personal devices cannot be guaranteed.
