Audio-Technica ATUC-IRDU Overview

  • 1Description

The Audio-Technica ATUC-IRDU is an IR discussion unit serving as a portable and flexible communication hub for ATUC-IR conferencing systems in academic institutions, corporate facilities, government buildings, conference spaces, and more. Its two multifunction talk buttons with multicolor LED bars, two 3.5mm headphone output with independent volume controls, and convenient built-in speaker make the ATUC-IRDU ideal for two-person conversation configurations.

Connect a gooseneck microphone (available separately) to the 3-pin XLR mic input, then position the ATUC-IRDU between two persons or place it in front of a chairperson. It can be powered by an AC adapter or via one or two rechargeable batteries for truly portable operation. An LED screen allows easy volume adjustment and channel selection, and other LEDs indicate power, battery, and talk status.
