Harman Pro AV systems equip Thai Defense Ministry

Thailand’s Office of the Permanent Secretary for Defense equips multipurpose hall with end-to-end Harman Professional Solutions AV, lighting and control systems.

Thailand’s Office of the Permanent Secretary for Defense has upgraded its HQ with Harman Professional Solutions AV, lighting and control systems.

Part of Thailand’s Ministry of Defense, the Office of the Permanent Secretary occupies a grand, nine-story building with multiple wings outside Bangkok. The organisation’s HQ includes a multipurpose hall that seats 1,500 and can be divided into two separate spaces on demand. 

“The client needed cutting-edge AV and stage lighting systems for the multipurpose hall that seats 1,500 people,” said Pongsakorn Kanchanachayphoom, director of project, Mahajak Development. “A robust and flexible solution was necessary to facilitate different types of events. Evaluating these requirements, we designed a system with Harman’s industry-leading networked AV and lighting solutions, providing the client with the required flexibility and allowing them to upgrade the platform in the future.”

To achieve the desired sound reinforcement in multiple room configurations, the Office of the Permanent Secretary installed a range of JBL loudspeakers in the main hall. When the hall is divided, 15-inch JBL AM7215 speakers serve the larger half, while 12-inch AM7212 models serve the smaller half. The speakers can be combined for maximum coverage across the entire hall, and the entire system is backed by STX828S dual 18-inch bass reflex subwoofers. JBL PRX800-Series monitors feature onstage, while JBL Control 328CT eight-inch coaxial ceiling loudspeakers provide additional coverage outside the hall.

Crown amplifiers were chosen to power the sound system, including the XTi 2 Series and the CDi 1000. Two Soundcraft Si Expression 3 digital mixing consoles were also installed. Networked together via a BSS Soundweb London BLU-100 signal processor, the two consoles can be configured to function independently or together, depending on the room configuration. 

Meanwhile, Martin MAC Quantum Series LED lighting fixtures were specified, with the MAC Quantum Profile serving as a main spotlight, and the MAC Quantum Wash providing washes of colour. Both fixtures feature Precise CMY color mixing and a variety of effects controlled by DMX. The hall also features 350- and 300-inch screens as well as 4K HMDI projectors equipped with projector lifts for positioning and stowing when not in use. To control the integrated AV and lighting systems, the facility is equipped with AMX touch panels. The control room, located next to the stage, features a 4.3-inch AMX wall-mount touch panel, while the facility’s main meeting room features a 9.7-inch panel.

“We wanted a system that would enliven the atmosphere of the multipurpose hall during seminars, performances and other events for our guests,” said a spokesperson for Office of the Permanent Secretary for Defense. “Harman’s diverse portfolio of products are easy to learn and manageable to support. They fulfilled every criterion of our request.”

“Harman is honored to be associated with the Office of the Permanent Secretary for Defence, and to be able to extend customised, multifaceted solutions through a unified platform,” said Ramesh Jayaraman, VP and GM Harman Professional Solutions, APAC. “We thank Mahajak for providing exceptional audio-visual and lighting solutions, and for creating an exceptional space that heightens the audience experience while encouraging participation.”
