Ratchaburi Provincial Stadium’s new high-tech audio system


The Ratchaburi Provincial Stadium in Thailand has had its existing sound system upgraded to support the number of sporting and entertainment events it hosts at the 10,000-seat venue.

The former home of and the former home of the Ratchaburi Mitr Phol Football Club, the event facility, has deployed a state-of-the-art AV system for greater clarity for vocal announcements and music.

The stadium operators worked with audio installation experts Mahajak Development, who chose a system from Harman Professional Solutions.

Mahajak Development equipped the 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 down for live performances and playback. It also chose 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 Crown DCi 2|600N, DCi 2|1250N and DSi 2000 amplifiers, which were selected for advanced digital signal processing capabilities. Audio is routed throughout the facility using BSS BLU-100 and BLU-50 digital audio signal processors.

“The customer requested an audio system that could deliver crystal-clear sound during speeches, live performances and other live events,” said Mr. Pongsakorn Kanchanachayphoom, project director, Mahajak Development. “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.”
