Featuring easy-to-use, plug-and-play functionality, and the choice of a wired or wireless system (or combination of the two), the ATUC-50 and ATUC-IR Digital Discussion Systems offer reliable, clear and intelligible communication to significantly increase meeting efficiency and effectiveness. The systems provide 24-bit/48kHz uncompressed digital audio for natural-sounding voice reproduction, along with a 12-band feedback suppressor that enables higher volume levels. 

The ATUC-50CU rack-mountable control unit drives wired-only systems. It can power and control a total of 100 ATUC-50DU discussion units, ATUC-50IU integration units, and ATUC-50INT interpretation units. Up to three ATUC-50CU control units may be cascade-connected via Cat5e (or better) cable. And with the aid of link extenders, this cascade-connection enables the use of up to 300 DU/IU/INT units in one system.* 

The ATUC-IRCU rack-mountable infrared control unit drives wireless or wired-wireless hybrid systems. It can power and control a total of 200 ATUC-IRDU infrared discussion units and 100 ATUC-50DU/IU/INT wired units. Up to two ATUC-50CU control units may be linked off of the ATUC-IRCU via Cat5e (or better) cable, providing an additional 100 wired DU/IU/INTs per 50CU for a grand total of 500 DU/IU/INTs.* 

Both the ATUC-50CU wired and ATUC-IRCU infrared control units feature 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 optional ATUC-IRCUDAN infrared control unit includes these inputs/outputs, plus a Dante™ output with redundancy. The control units are 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). When the 2 GB limit is reached, a new file can be created to continue recording. Up to four channels are available for recording WAV files; up to two channels are available for recording MP3s.
