Ratchaburi Provincial Stadium, Thailand

The Opportunity

Ratchaburi Provincial Stadium is a world-class stadium and the former home of the Ratchaburi Mitr Phol Football Club. With over 10,000 seats, Ratchaburi Provincial Stadium is Thailand’s premier live event facility for sporting events, performances and more. To deliver clear, intelligible sound for announcements and music throughout the stadium, Ratchaburi Provincial Stadium required a comprehensive networked AV system.

The Solution

Mahajak Development equipped Ratchaburi Provincial Stadium with JBL PD566 full-range loudspeakers to deliver clear, intelligible sound with broad, even coverage. JBL PD525S high-output subwoofers provide deep, powerful low end for live performances and playback. Mahajak Development selected JBL AWC129 all-weather coaxial loudspeakers for their compact, weather-resistant design and high SPL capabilities. JBL LSR305 studio monitors were installed in the control room to deliver neutral, accurate sound for critical listening.

The system is powered by industry-leading Crown DCi 2|600N, DCi 2|1250N and DSi 2000 amplifiers, which were selected for their unparalleled efficiency and advanced digital signal processing capabilities. Audio is routed throughout the facility using BSS BLU-100 and BLU-50 digital audio signal processors.

The Impact

“The customer requested an audio system that could deliver crystal-clear sound during speeches, live performances and other live events,” said Pongsakorn Kanchanachayphoom, Project Director, Mahajak Development Co., Ltd. “Mounting a speaker on the roof of the stadium proved to be a bit of a challenge, as it needed to be specifically positioned for maximum impact throughout the seating area. But, after careful and precise measurements, we were able to achieve the desired result.”

“We required a customized audio solution for the new stadium that would deliver consistent coverage and vocal clarity for announcements and live performances,” said a spokesperson from Ratchaburi Provincial Stadium. “We were confident that Mahajak could design a system that met our requirements, and they have definitely lived up to our expectations. We’re highly satisfied with our new HARMAN system, which delivers exceptional audio quality and complete coverage.”
