Jakarta, Indonesia (October 13, 2020)—Nestled inside the Jakarta International Expo (JIExpo) centre for meetings, events and arts performances is the JIExpo Theatre, a brand-new venue seating 2,500. “The venue was originally specified to be just a theatre, but I saw the potential to make it also serve as Indonesia’s largest concert hall,” said managing director, Prajna Murdaya.
Key to the facility is its Meyer Sound Constellation acoustic system, provided through Meyer Sound national distributor Mega Swara and installed by Jakarta-based integrator Kairos Multi Jaya. A total of 285 small, self-powered loudspeakers (MM-4XP miniature and UP-4XP full range plus UMS-1XP subwoofers) are deployed throughout the auditorium to create natural acoustical environments uniformly throughout the large space. Processing is handled by Meyer Sound’s multi-module D-Mitri Digital Audio Platform, with 51 microphones distributed overhead for sensing the ambient acoustics.
For events requiring amplification, the JIExpo Theatre provides a direct reinforcement system anchored by LEOPARD line array loudspeakers, with arrays of 12 per side to cover the first two levels and an additional set of four per side for the uppermost level. Deep bass is supplied by a cardioid configuration of five 1100-LFC low-frequency control elements flown over center stage. Center channel loudspeakers are UPQ-1P, with UPJ-1P loudspeakers as side fills and UPM-1P loudspeakers for front fills as well as under- and over-balcony fills. The system can be used with Constellation off, or with acoustical enhancements added for a variety of pop, rock, jazz and musical theatre performances.
Among first events was a concert by cellist Yo-Yo Ma—his first in Indonesia—for which the Constellation system remained on throughout, extending the theatre’s RT60 baseline physical acoustic from 1.2 seconds to 2.2 seconds. The system allowed the theatre’s technical manager, Bayu Wicaksana, to customize the response for the cellist’s instrument. Ma’s rendition of six suites for cello by Johann Sebastian Bach drew extended standing ovations from the audience.
Other key contributors in the design phase were theatre consultants Philip Soden and WSDG acoustic consultants. The Meyer Sound contingent was led by Constellation Project Director John Pellowe with design and tuning of the direct reinforcement system supervised by Director of System Optimization Bob McCarthy.
JIExpo Theatre boasts one of the largest stages in Asia, measuring 48 m wide by 16 m deep and expanding up to 21 m deep following renovations with the orchestra pit covered. The theatre is the latest addition to the larger exposition complex, which first opened in 2010.
