In 2003, Axia Audio, the studio audio division of the Telos Alliance, invented Audio-over-IP for broadcasting. We did what no one had ever done before: created professional radio gear that networks, using standard Ethernet, for use in digital audio routing, mixing and distribution systems for broadcast and other pro-audio applications.


The foundational technology in all Axia products is Livewire+, a patented AoIP protocol that enables high-reliability, low-delay uncompressed digital audio over Ethernet. Axia Livewire+ has built in compliance with the AES-67 standard. Axia and its parent company, The Telos Alliance, are committed proponents of AoIP interoperability -- first as charter, supporting members of the X192 Working Group which defined AES-67, and now as members of the Media Networking Alliance, a group of prominent broadcast equipment manufacturers formed to actively promote the adoption and implementation of the AES67 standard.


Every Axia product is networked using Ethernet - including audio, logic, control and program associated data, or "PAD". Devices connect together using standard Ethernet cables; audio and control routing is accomplished with off-the-shelf Ethernet switches.


Today, Axia mixing consoles, digital audio routers, broadcast intercom systems and routing control software are the world's standard in networked broadcast studio technology, with more than 5,500 mixing consoles and over 50,000 networked audio devices - many from Axia Livewire+ Partners - powering broadcast studios around the globe. There's also an Axia Users Forum where Axia fans can ask questions, share tips and ideas.


Marty Sacks, Vice President of Axia Audio, about RAVENNA:

"Ever since we launched Livewire in 2003 as the first IP audio protocol for broadcasting, we’ve been dreaming of the day when every piece of broadcast equipment is connected to the network. After all, a network that connects only to itself is not very useful! With 34 Livewire partners and 32 RAVENNA partners now on board, broadcasters will benefit immediately from a dramatically expanded universe of networked pro audio products that can work together. And even more partners and products will become available over time.


Now that Axia and RAVENNA developers are working together, the broadcast world is now one giant step closer to that networked vision becoming reality."
