Cirrus Logic Inc. (Nasdaq:CRUS) The 15 million anticipated visitors
to the 2005 World Expo in Aichi, Japan, are experiencing superior
audio performances at the Expo Hall thanks to the teaming of
Yamaha's professional audio equipment and Cirrus Logic's
CobraNet(TM) digital audio over Ethernet technology. The CobraNet
digital audio system, adopted by the 2005 World Expo for
implementation in the Expo Hall, will provide an extremely clear,
high-quality acoustical environment for the daily Expo Hall
performances celebrating a wide variety of cultures around the
world. The Expo Hall is an interior hall accommodating 440 people
and was designed for a conventional all-in-one mixer at the center
of a cutting-edge sound system that networks the audio signals and
control signals via CobraNet technology, the leading standard for
delivering digital audio over Ethernet networks. "We are proud that
Yamaha chose CobraNet technology to create some of the most
powerful entertainment experiences, and especially honored to be
participating with Yamaha at the 2005 World Exposition Aichi," said
Keith Cheney, vice president and general manager, Cirrus Logic
Embedded Products Division. "Yamaha's selection of CobraNet
technology for its equipment at the 2005 World Exposition
underscores CobraNet's position as the leading standard for
delivering networked digital audio." CobraNet technology is being
used between front-of-house (FOH) and the stage-wing (stage right)
PM5D mixing consoles and DME64Ns Digital Mixing Engines from
Yamaha. The control room PM5D handles FOH duties, while the stage
wing right PM5D handles monitoring. Output processing is handled by
the Yamaha DME mixing engines. The audio mixed by the control room
PM5D and DME64N (which performs the PM5D's matrix extension) is
transmitted digitally via CobraNet to another DME64N (stage right).
The system utilizes an optical cable between the DMEs with a
secondary link for fault tolerance/reliability purposes, and
24-bit, 48 kHz digital audio is being transported with a low
latency of 1.33ms. The Yamaha system further utilizes an Expo Hall
installed wireless LAN, allowing the DME64N's to be operated by a
Tablet PC so that adjustments can be made while standing in front
of the monitor speakers, allowing for real-time tuning. In
addition, the PC-N series power amps (placed in the wings) can be
controlled and monitored at all times from the control room using
the ACU-16C amplifier control unit via CobraNet technology. With
Cirrus Logic's CobraNet Silicon Series of integrated circuits,
Cirrus Logic is enhancing CobraNet's position as the leading
standard for distributing uncompressed digital audio over Ethernet
networks. Devices that can now incorporate CobraNet technology
includes power amplifiers, self-powered loudspeakers, signal
processors, intercom systems, large facility audio distribution via
ceiling speakers, paging stations, broadcast equipment and home
automation consumer products. The 2005 World Exposition Aichi runs
through Sept. 25, 2005. Yamaha Corporation YAMAHA CORPORATION
