Ryuuji Kasuga, Panasonic System Solutions Marketing (PSSM); Nobuyuki Takezaki, PSSM; Shiyogo Hayashi, Bestec Audio; Yoshiteru Mimura, consultant; and Masaki Hara, Bestec Audio. Japan (August 21, 2007)–Nagai Stadium in Osaka recently became the first stadium in Japan with a fully digital audio network and control system following a major upgrade that included the installation of seven Dolby Lake Processors for speaker optimization. The project, under the auspices of consultant Yoshiteru Mimura of Archito Co. Ltd., based in Kyoto, with installation by Panasonic, provides control and EtherSound audio distribution via a Gigabit network in a redundant ring topology comprising 2.5 km of fiber.
Mimura remarked, “When passing digital audio through the Dolby Lake Processor the jitter performance improved by a significant amount, which has an important bearing on the overall audio performance. Everyone who tested it now knows why the system sounds so good,” he said.
The Dolby Lake Processors, accessed from a PC in the main control room and from a wireless tablet that also acts as a secondary controller, provide crossover and local delay control for the zoned L-Acoustics speakers and Crown amplifiers distributed around the stadium. “The Dolby Lake Processor provides very useful filters, especially the Mesa EQ, to really help in system tuning,” said Mimura.
Originally completed in 1996, the 50,000-seat Nagai Stadium is home to the Cerezo Osaka soccer club and will host the 2007 Athletics World Cup in August. The Dolby Lake Processors were provided by Dolby Live Sound’s Japanese distributor, Bestec Audio Inc.
