The 19" rack-mountable ATUC-IRCU control unit enables the use of both infrared and wired discussion units, providing 24-bit/48 kHz digital signal processing (with 12-band feedback suppressor), automated gain control (AGC), mic gain and mic EQ for each connected discussion unit. The control unit can be operated locally, through the Web Remote interface (no software required), or third-party IP control systems. It offers three selectable conference modes (Free Talk, Request to Talk, and Full Remote) and various override settings.
The ATUC-IRCU can power and control a total of 200 ATUC-IRDU infrared discussion units and 100 ATUC-50DU/IU wired units. Up to two ATUC-50CU control units can be linked from the ATUC-IRCU via Cat5e (or better) cable, providing an additional 100 wired DU/IUs per 50CU for a grand total of 500 DU/IUs.
The control unit features four balanced outputs and one unbalanced output, plus left/right AUX RCA inputs, two mic/line inputs, and two interpretation return inputs to provide simultaneous interpretation feeds in addition to the floor language feed. The control unit is equipped with an audio recorder that can record MP3 or WAV files of 2 GB or less onto a connected USB mass storage device (2 TB max. storage capacity).
