Harman Raises The Roof At Nakhon Ratchasima Sports Complex

Home to the Nakhonratchasima Mazda Football Club, the Nakhon Ratchasima Sports Complex is the fourth biggest stadium in Thailand and hosted the Southeast Asian (SEA) Games in 2007.

That same year, King Rama IX bestowed the complex’s name during an overlap between the SEA Games and the king’s birthday.

The stadium area comprises the Nakhon Ratchasima FC football field, which is surrounded by a grandstand with a single roof on one side. The facility currently has a seating capacity of 25,000, but will be upgraded to 45,000 in the future.

Recently, the complex’s organisers requested a new high-output audio system capable of providing clear, intelligible sound with reduced reverberation during games and events.

The main challenge was that the audio system needed to be installed on the roof, which only covered one side of the complex, but also had to deliver sound coverage to every seat in the stadium.

To meet these challenges and requirements, Mahajak Development Co., Ltd deployed dynamic and weather-resistant JBL Professional speakers, Crown audio amplifiers, Soundcraft consoles and BSS signal processors for wide coverage, ample output and easy-to-use controls.

For speakers, the Mahajak team selected JBL PD500 Series loudspeakers to cover the roof side of the grandstand and JBL Variable Line Array Compact Series line array loudspeakers to cover the rest of the venue.

In addition to the under balcony, the Mahajak installation team also installed JBL Control 29AV-1 speakers powered by a Crown CDi series amplifier (configured using a dbx VENU360 signal processor) in the corridor outside of the stadium for clear and high-quality background audio.

“A unique, historical venue like Nakhon Ratchasima Sports Complex requires powerful audio systems to enliven the fan experience and create an exciting atmosphere during sports events, competitions and concerts,” said Amar Subash, director, channel management and audio solutions, Harman Professional Solutions, APAC.

“We would like to thank our partner Mahajak Development for delivering yet another successful project and resolving the challenges with innovation and proficiency.”
