Cirrus Logic Takes CobraNet to Heathrow Airport, Olympics, Europe

1/29/2004 - The Commercial Audio Products business of Cirrus Logic Inc. (Nasdaq: CRUS) announced agreements with three companies — Netherlands-based Bosch Security Systems, U.K.-based Novar Intelligent Building Systems (IBS) and Atlanta-based Commentary Systems — to purchase and use Cirrus Logic's CobraNet technology in their products.

With these new agreements, there are now 41 licensees of Cirrus’ CobraNet technology, which is the professional audio industry’s leading technology for distributing uncompressed, real-time, digital audio over a Fast Ethernet network. CobraNet technology is being utilized in several prominent venues, including the Sydney Opera House, Wembley Stadium and several of the world’s largest theme parks and major sporting events venues.

For Bosch Security, the agreement enables the company to design a CobraNet interface into all of their products, starting with its Praesideo family of sophisticated digital emergency sound and public address systems used in medium to large public facilities. Scheduled for commercial availability in mid-2004, the Praesideo CobraNet interface will allow multiple Praesideo systems to be connected via Ethernet, increasing the total number of zones allowed or covering long distances. In addition, links between a Praesideo system and a third-party system can be created by using CobraNet technology.

Novar IBS will utilize CobraNet to distribute high-quality audio in the public address systems that it is installing in Heathrow Airport's prestigious new Terminal 5. The first product to feature CobraNet technology will be the integrated fire detection, voice alarm and public address system currently under development. "Incorporating some 30,000 fire detection points and 100,000 loudspeakers, Novar identified CobraNet as the ideal technology to provide deterministic audio distribution while allowing the use of industry-standard hardware to integrate third-party products," said Ian Archer, Novar IBS.

Atlanta-based Commentary Systems develops and manages broadcast sound systems for transmitting news coverage of international sporting events, including the Olympics and World Cup. It is integrating CobraNet technology into its latest digital broadcast solution, which gives an event commentator full level control and ear selection from up to eight audio sources. With CobraNet, the system offers digital audio transmission directly from broadcasters to their home-country destinations via ISDN.

"The use of the CobraNet technology in these applications demonstrates how CobraNet continues to meet large-venue demands for high-quality distributed audio," said Rich Zwiebel, vice president, Commercial Audio, Cirrus Logic. "From its selection for the new Heathrow Terminal, which is one of the U.K.'s largest construction projects, to its application in broadcasting major international events and use in Europe's hotels and railway stations, CobraNet is proving to be the distributed audio technology for the future."

Driving CobraNet’s success further, Cirrus recently introduced the CS18101 digital audio networking processor, the first release of CobraNet technology integrated into an IC. This single-chip solution enables Cirrus customers to implement CobraNet technology more cost effectively than previous methods that utilized more expensive circuit boards.
