The ATUC-IRCUDAN infrared control unit is part of Audio-Technica's Hybird Infrared Discussion System. It's the Dante™-equipped version of the ATUC-IRCU (sold separately). It provides 24-bit/48 kHz digital signal processing power to both infrared and wired discussion units (additional units sold separately), for natural-sounding voice reproduction, and delivering reliable, clear and intelligible communication for significantly enhanced meeting efficiency and effectiveness. This 19", rack-mountable unit also includes automated gain control (AGC), mic gain and mic EQ for each connected discussion unit within its system. It operates via local Web Remote interface or over third-party IP control system. A variety of override settings and 3 conference modes are selectable to ensure smooth conferencing: Free Talk, Request to Talk, and Full Remote. It's conveniently equipped with an audio record function that can record MP3 or WAV files of 2 GB or less onto a connected USB mass storage device (2 TB maximum storage capacity). When the 2 GB limit is reached, a new file can be created to continue recording. Up to 4 channels are available for recording WAV files; up to 2 channels are available for recording MP3s.

Inputs/Outputs (I/O), including Dante

It features 4 balanced outputs and 1 unbalanced output, plus left/right AUX RCA inputs, (2) mic/line inputs, and (2) interpretation return inputs to provide simultaneous interpretation feeds in addition to the floor language feed, plus a Dante output with redundancy.
