Audio-Technica ATUC-IRCU Hybrid IR Control Unit

Overview of Audio-Technica ATUC-IRCU Hybrid IR Control Unit

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).

Features:

• Crystal-clear, 24-bit digital audio processing with 12-band feedback suppressor
• Easy plug-and-play operation for wired, infrared, and hybrid discussion systems
• Each ATUC-IRCU infrared control unit supports a maximum of 200 ATUC-IRDU discussion units and 100 ATUC-50DU/IU units (use of ATLK-EXT165 link extenders may be required)
• Up to 500 microphones can be cascade-connected from the control unit (300 50DU units and 200 IRDU units)
• Systems can be configured in either daisy chain or ring topology
• Three selectable operation modes (Free Talk, Request to Talk, and Full Remote), plus various override settings
• Built-in WAV and MP3 recorder lets you record to a USB mass storage device
• Four configurable balanced matrix output plus one unbalanced output that outputs the same audio as Output 1
• Two Mic/Line inputs, two AUX inputs, and two return inputs
• LED indicators on front panel allow for easy monitoring of critical system functions
• Front panel OLED displays active system information and presets
• Settings and operation can be handled locally at the control unit, through the Web Remote interface, or via third-party IP control systems
• Individual automated gain control (AGC), mic gain and mic EQ for each discussion unit
• Expandable and scalable system design
