Digital Conference System
Product Description
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.*
