AXIA | CONSOLES | APPLICATION ARTICLE 70 MULTILINGUAL, MULTI-STUDIO IP-AUDIO AT RADIO FREE EUROPE / RADIO LIBERTY In the decade since IP-Audio networking technology irst debuted to the broadcasting community, thousands of studios, from large to small, have been built around it. Still, in conversation, people not familiar with the technology still ask, “Is AoIP really robust enough for round-the-clock radio?” On those occasions, the exciting operation that is Radio Free Europe / Radio Liberty, located in the Czech Republic capital of Prague, comes quickly to mind as a shining example of just how robust Audio-over-IP is. The impressive new home of Radio Free Europe / Radio Liberty For more than 60 years, Radio Free Europe and Radio Liberty have been broadcasting news, information and discussion to millions of listeners throughout Europe and Central Asia. RFE/ RL, as it’s commonly known, originates more than 1,000 hours of programming per week, in 28 languages and broadcast to more than 20 countries. That’s a lot of programming, and it requires a stout infrastructure to keep it all running smoothly, hour after hour, 365 days a year. Originally headquartered in Munich, Germany, RFE/RL moved to Prague in 1995. For the next 13 years, they occupied what had been the Soviet-era Czech Parliament building in historic Wenc- eslas Square. It served its purpose, but the structure had been built to fulill a different kind of mission – one almost diametri- cally opposed to the one it now served, as a free disseminator of news and information. As the service approached its sixth decade and looked to its future, it was clear that to both grow and update, it would have to move to a new HQ. The plan, as it evolved, was this: relocate RFE/RL to a new, modern, purpose-built facility in Hagibor, outside of Prague’s bustling center. RFE’s new house would be big, with more than 200,000 square feet to contain the activities of over 500 employees daily. Bill Cline inspects RFE’s Axia “test studio,” September, 2007 RFE/RL’s Director of Broadcast Engineering, Bill Cline, was intimately involved in the new studios’ design. He liked the lexibility of networked audio, and oversaw the building of studios using Axia consoles and IP-Audio networking equipment in 2007; the success of those tests conirmed that Axia Livewire AoIP was up to the operational requirements of a large operation like Radio Free Europe’s.

In 2009, the new RFE/RL headquarters was placed in service. It is one of the largest radio origination facilities in the world; in addition to radio programming, the new facility houses an enormous news gathering organization and TV distribution facilities as well. The radio broadcasting “suite,” if something so large can be called that, consists of 49 on-air and production studios. Axia consoles and IP-Audio equipment are the basis for them all. While large, this is well within Axia’s system capacity, which is able to route and transport up to 30,000 stereo audio channels. Among RFE/RL’s unique operational requirements is the abil- SOFTWARE UPDATES AXIAAUDIO.COM/DOWNLOADS ity to monitor any of its programs from anywhere in the facility. With so many studios producing programs in so many languages, this may seem like no small undertaking! However, Axia and Telos technology and equipment make this easy and elegant. Banks of Telos iPort MPEG Gateways are employed to handle the task. These devices connect directly to Axia net- works; using iPort, RFE converts all of its audio programming directly from Livewire IP-Audio to Multicast MP3 streams, which are available at listening stations or on PCs anywhere in the facility. Each iPort is capable of encoding up to 16 MP3 streams at once. RFE/RL studio setup features super-redundant distributed core/edge architecture with multiple network connection paths.
