Overview

The 19" rack-mountable ATUC-IRCU allows for 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. It can be operated locally, through the Web Remote interface (no software required), or third-party IP control systems. Offers three selectable conference modes (Free Talk, Request to Talk, and Full Remote) and various override settings. Can record WAV and MP3 files onto a connected USB mass storage device. Includes two Mic/Line inputs, two AUX inputs and two interpretation return inputs. For wired or wireless systems.

Features

• Each ATUC-IRCU infrared control unit supports a maximum of 200 ATUC-IRDU discussion units and 100 ATUC-50DU/IU/INT units
• Systems can be configured in either daisy chain or ring topology
• Unlike typical UHF wireless systems that broadcast through walls, the ATUC-IR infrared transmission keeps your signals safe and secure, with no information leakage
• IR transmission does not require any form of frequency coordination
• Built-in WAV and MP3 recorder lets you record to a USB mass storage device
• Control available through Web Remote interface and third-party IP Control Systems
