The Audio-Technica ATUC-IRD is a compact IR distribution unit designed to extend the infrared transmission area of a wired or wireless ATUC-IR conferencing system in academic institutions, corporate facilities, government buildings, conference spaces, and more. Connect the antenna output from your ATUC-IRCU or ATUC-IRCUDAN control unit to the single BNC input on the ATUC-IRD, then route its two BNC outputs to separate ATUC-IRA transceivers (available separately). Multiple ATUC-IRDs can be used to accommodate up to four transceivers per TX/RX terminal on a control unit. The ATUC-IRD's integrated mounting bracket enables easy installation to a wall, ceiling, or desk via two optional screws.
