Sonifex has announced a range of AoIP Talkback/Listening/Paging intercoms using Ravenna/AES67 networking.

Sonifex AVN-TB10AR intercom

The first intercom to be released is the AVN-TB10AR, a ten-button, ten-station device. Comms can be made as a Talk action, a Listen action or a duplex Talk/Listen action to/from each station. RGB LEDs in the key-cap 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, together with a Callback list on the front panel display. The stations can be anywhere on the AoIP network with auto-discovery of new stations.

Sonifex reckons these products to use new technology to their best advantage, offering solutions that are powerful and configurable with very simple Cat5e cabling. Each unit has both 4-wire and AoIP connectivity, with all audio transferred over a network, enabling it to be used in existing legacy systems, or in completely new AES67 AoIP networked audio infrastructure. With dual 1Gb LAN ports and a 1Gb SFP fibre port the products can be used in larger networks too

Advanced acoustic echo cancellation & built-in microphone AGC (automatic gain control) ensure that there’s no acoustic feedback between microphone and speaker. Additionally, all audio is at 48kHz sample rate, meaning that it’s broadcast quality audio as standard.
