ATUC-IRDU IR Discussion Unit

IR Discussion Unit


Whatever your conferencing or discussion needs, the ATUC-IR is designed to offer reliable, clear and intelligible communication to significantly increase meeting efficiency and effectiveness.

Voice is the quickest and most efficient tool for exchanging ideas - whether in meeting rooms, councils, classrooms or through videoconference, speech is the most direct way of communication and understanding.

In the digital era, the control of information is paramount. With an infrared conference system your wireless signal will not leave the room; it is impossible to capture from another building, for example. Compared to a UHF system (radio waves), which behaves in the same way a radio station transmitting over a broad area, the infrared system excels at protecting your information, since no leakage is possi

Via IR transmission, the ATUC-IRDU connects easily with the ATUC-IRCU (ATUC-IRCUDAN).
