 Talkback Intercoms Using Audio Over IP, RAVENNA/AES 67
Our new range of AVN (Audio/Video/Network) talkback/listening/paging intercoms aid communication between studios, stages, theatres, offices and different areas in a facility or building complex. They have both 4-wire and AoIP sources and destinations, and use RAVENNA/AES67 as the audio transport mechanism, allowing simple CAT 5 cabling and expansion.

 

Webserver Software

Each AVN-TB talkback unit has a built-in webserver for setup and configuration. The webserver is responsive, and resizes depending on the size of your screen, meaning that it can be used on large monitors or small handheld devices such as smart-phones. Help information is shown on the right hand side of the screen so it?s a good place to go to find out how the unit operates.
