ATUC‑50CU Wired Discussion System Control Unit
- 19" rack‑mountable control unit for wired discussion systems
- 24‑bit / 48 kHz DSP with 12‑band feedback suppressor
- Three selectable conference modes: Free Talk, Request to Talk, Full Remote
- Expandable system supporting up to 300 discussion units
- Built‑in WAV/MP3 recording to USB mass storage
The ATUC‑50CU is a powerful, rack‑mountable control unit designed to drive wired discussion systems in conference rooms, council chambers, and meeting spaces. It delivers crystal‑clear digital audio processing and comprehensive system control for professional discussion environments.
Featuring advanced 24‑bit / 48 kHz DSP, the ATUC‑50CU provides individual automated gain control (AGC), microphone gain, and EQ for each connected discussion unit. Operation is simple and flexible, with control available locally, via a web‑based remote interface, or through third‑party IP control systems.
Conference Modes & System Control
The ATUC‑50CU offers three selectable conference operation modes to suit different meeting styles and governance requirements.
-
Free Talk: Participants can activate microphones freely
-
Request to Talk: Microphone activation is managed through requests
-
Full Remote: Microphones are controlled centrally by an operator
Scalable & Expandable System Design
Each ATUC‑50CU can power and control up to 100 ATUC‑50DU discussion units and ATUC‑50IU integration units. Up to three control units can be cascade‑connected via Cat5e (or better) cable, enabling systems with up to 300 DU/IU units when used with link extenders.
Systems can be configured in either daisy‑chain or ring topology, offering flexibility for different room layouts and installation requirements.
Audio Inputs, Outputs & Recording
- Four configurable balanced matrix outputs
- One unbalanced output mirroring Output 1
- Two Mic/Line inputs
- Two AUX RCA inputs
- Two interpretation return inputs for simultaneous interpretation
The integrated audio recorder allows recording of WAV or MP3 files (up to 2 GB per file) directly to a connected USB mass storage device (up to 2 TB supported), providing simple archival and documentation of meetings.
User Interface & Monitoring
Front‑panel LED indicators allow quick monitoring of critical system functions, while the OLED display provides clear visibility of active system information and presets.
Settings and system operation can be handled directly from the control unit, through the Web Remote interface (no software installation required), or via compatible third‑party IP control systems.
Ideal Applications
- Conference rooms and boardrooms
- Government and council chambers
- Corporate and institutional meeting spaces
- Facilities requiring scalable, wired discussion systems
