Audio-Technica ATUC-IRCU IR Hybrid Discussion System Control Unit

The Audio-Technica ATUC-IRCU is a 19-inch rack-mountable control unit designed for the ATUC-IR hybrid discussion system. This central unit enables the seamless integration of both infrared and wired discussion units, utilizing 24-bit/48 kHz digital signal processing to deliver high-fidelity audio. Each connected unit benefits from dedicated automated gain control (AGC), mic gain, and mic EQ to maintain consistent audio quality across the entire system.

Advanced Audio Processing

The ATUC-IRCU features a 12-band feedback suppressor that eliminates unwanted noise and interference. The 24-bit digital audio processing ensures crystal-clear communication during conferences. The system allows for precise adjustments of individual microphone parameters, ensuring every participant is heard clearly regardless of their environment.

System Capacity and Scalability

This control unit offers extensive scalability for large-scale installations. A single ATUC-IRCU supports up to 200 ATUC-IRDU infrared discussion units and 100 ATUC-50DU/IU wired units. For larger requirements, users can link up to two ATUC-50CU control units via Cat5e or better cabling. This configuration allows for a maximum of 500 discussion units in a single system. The architecture supports both daisy chain and ring topologies to provide flexible installation options and system redundancy.

Versatile Operational Modes

The ATUC-IRCU provides three selectable conference modes to accommodate various meeting structures:

• Free Talk: Allows open discussion between participants.
• Request to Talk: Manages speaker priority through a queue system.
• Full Remote: Provides total control over the discussion flow.

Various override settings allow administrators to manage the discussion effectively based on the specific needs of the session.

Comprehensive Connectivity

The unit includes a robust array of inputs and outputs for professional audio integration:

• Outputs: Four configurable balanced matrix outputs and one unbalanced output that mirrors Output 1.
• Inputs: Two Mic/Line inputs, two L/R AUX RCA inputs, and two interpretation return inputs.
• Interpretation: The return inputs facilitate simultaneous interpretation feeds alongside the floor language feed.

Integrated Recording and Monitoring

An onboard audio recorder allows for direct capture of proceedings to a USB mass storage device. The system supports both MP3 and WAV file formats with a maximum file size of 2 GB and a total storage capacity of 2 TB. For system monitoring, the front panel features an OLED display showing active system information and presets, while LED indicators provide real-time status updates for critical functions.

Flexible Control Options

Administrators can operate the ATUC-IRCU locally at the unit, through a Web Remote interface that requires no additional software, or via third-party IP control systems. This versatility ensures the system integrates easily into existing AV infrastructures and allows for efficient remote management.
