The Williams AV IR SY22 D is an infrared (IR) assistive listening product, transmitting audio as modulated infrared light rather than radio waves. Because IR light can't pass through walls, these systems keep audio confidential room-to-room and are immune to RF interference, which is why they're the standard choice for courtrooms, legislative chambers, and other venues where audio privacy is required. The Dante-equipped (D) version networks the transmitter digitally over standard Ethernet for easier integration with house sound systems. Typical installations include courtrooms, legislative chambers, theaters, and classrooms needing ADA-compliant, interference-free listening.
