Whether it is a huge stadium where thousands of people are shouting and celebrating, or a small sport center for practice or leisure, TOA always pursues the qualities of the sound to create dynamic sound spaces for participants to enjoy the excitement.
Gelora Bung Karno Stadium – Indonesia
When Jakarta’s Gelora Bung Karno Stadium opened in 1962 it was one of the largest sports stadiums of its kind in the world, and for decades it has remained familiar as the home of the Persija Jakarta professional football club. In 2016 and 2017 the stadium was treated to a major renovation, both to repair its aging facilities due to safety concerns and to refurbish it as a central venue for the 2018 Asian Games.
Among the renovations was the installation of a powerful sound system capable of delivering announcements clearly audible over the roar of 90,000 cheering fans. TOA brought in technology and expertise from Japan, but also worked with local Indonesian partners to create and build this sound system.
To achieve good sound reproduction in the higher frequency ranges—usually considered difficult with horn speakers—TOA developed a unique driver unit employing a ring-shaped diaphragm, which is the first of its kind in the world. We also improved the driver’s overall durability by incorporating a radiation fin with a new shape, and installed 8-horn speaker arrays utilizing these new drivers in twelve locations around the stadium. In addition, combining each horn array with a Line Array Speaker Type C subwoofer ensures adequate coverage in the lower frequency ranges, thus achieving both the level of sound pressure and good sound quality required in such a large, open outdoor space.
This sound system is the largest TOA has ever installed in a stadium of this scale. It’s clear, uniformly distributed sound and acoustic environment delivering realism and power will be relied upon to convey the excitement of sporting matches, and its high-definition sound quality will undoubtedly be utilized for all manner of musical performances and other live events in the future.
Wimbledon Tennis Courts – United Kingdom
London's Wimbledon Tennis Court is the U.K.'s largest tennis venue and home to the Wimbledon Championships, where players of the highest caliber battle it out in one of the world's most prestigious annual tournaments. Here, a public address system based on TOA's SX-2000 Series Smart Matrix System and digital power amplifiers helps ensure the smooth progress of every match.
This system allows free selection of multiple broadcast areas within the facility, including courts, restaurants, and museum, directing the right information wherever it's needed. Built-in redundancy quickly handles any potential malfunction, and in the event of fire or other emergency, the system switches to deliver evacuation and information announcements from the emergency center. Speakers lining the walls of the court areas are designed to harmonize with the elegant, relaxed atmosphere, while delivering clear, high-quality sound to match.
Cartoon Network Amazone – Thailand
Cartoon Network Amazone – Thailand is one of the largest family-oriented water parks in Asia with Cartoon Network as theme; located in Pattaya, Thailand. TOA supports the establishment of a broadcasting system, including line array speakers on the main stage.
Beijing National Stadium - China
Beijing National Stadium - China, also popularly known as the “Bird’s Nest,” was the main stadium of the 2008 Beijing Olympic Games. During the games, football and track and field events were held in this stadium, as well as the spectacular opening and closing ceremonies. The biggest issue in the installation of TOA’s systems was how to provide correct and accurate broadcasting that would allow for smooth game operations in a gigantic stadium boasting a seating capacity of as many as 91,000 spectators.
A combined broadcast system composed of the SX-2000 Series Matrix system and the VX-2000 Series Integrated Emergency Public Address system provides background music and general announcements. It also offers easy selection of multiple sound sources for free broadcast to multiple areas through a combination of HX-5 Series Variable Dispersion speakers and ceiling mounted speakers for smooth sound distribution. In case of fire or other emergencies, the system instantly connects to external public address equipment for evacuation announcement to ensure the safety of both spectators and participants. Additionally, extensive failure detection functions programmed into the system ensure that system troubles and failures can be quickly remedied. After the Olympic Games were completed, the stadium was remodeled and the installed TOA systems are expected to be used in a wide assortment of future applications ranging from sports to music concerts and other entertainment events.
