Sonifex TB10AR

Sonifex Announce Talkback Intercoms Using AoIP, RAVENNA/AES 67

 

The new range of Sonifex AVN (Audio/Video/Network) talkback/listening/paging intercoms aid communication between studios, stages, theatres, offices and different areas in a facility or building complex. RAVENNA (of which AES67 is a subset) allows for the distribution of audio across a network. The AVN range use RAVENNA as the communication method providing compatibility with other AES67 systems and allowing simple CAT 5 cabling and expansion.

 

The AVN-TB products are IP audio based talkback intercom units with an advanced feature set, allowing them to be used in multiple applications. With both 4-wire analogue inputs and outputs, as well as AoIP network audio connectivity, the AVN-TB units can be used with existing legacy 4-wire systems and with new AES67 AoIP networked audio infrastructure. Additionally, all audio is at 48kHz sample rate, meaning that it’s broadcast quality audio as standard. With dual 1Gb lan ports and a 1Gb SFP fibre port the products can be used in larger networks.

 

The first intercom to be released is the AVN-TB10AR, a 10 button intercom meaning that 10 other ‘stations’ can be defined, one per button, for communication. Comms can be made as a Talk action, a Listen action or a duplex Talk/Listen action to/from each station. Coloured LEDs in the buttons help to show which action is being used and there is also a Callback button for when you’re unavailable to receive a call.

 

The stations can be from anywhere on the AoIP network and the use of Bonjour Device Discovery means that other stations can be found quickly and easily.

 

Advanced acoustic echo cancellation & built-in microphone AGC (automatic gain control) ensure that there’s no acoustic feedback between microphone and speaker.

 

Each unit has a built-in webserver which is where the majority of settings and configurations are made. The front panel OLED display can also be used to configure the unit, although more functionality is available by using the webserver. The webserver is a responsive design meaning that it can be used with small screens on smartphones and tablets.

 

The unit has a front panel power button and dual power connectors - an IEC mains input and a 12V DC input, which allows the AVN-TB10AR to be used for both studio and mobile installations. Also, a secondary power source reduces the effect of power down events. In any case, the unit monitors the status of both power sources and displays this on the front panel.
