Harman Professional Solutions, in collaboration with AV integration partner Ba Sao Audio, recently deployed one of the region’s first large-scale spatial audio deployments for live theatre.
Conceived by Nguy?n Kh?c Anh, CEO of Ba Sao Investment, with technical direction by Vu H?u Th?ng, CHÀO reimagines Vietnamese heritage through a compelling fusion of traditional music, dynamic visuals, and immersive sound design. The performance features an original orchestral suite with 30 traditional Vietnamese instruments, supported by a massive 150-square-metre LED screen and synchronised lighting.
From a technical standpoint, CHÀO posed a unique challenge. The performers and the audience occupy a shared acoustic environment, with no stage monitors or in-ear systems. This required precise spatial mixing and system tuning to maintain instrument fidelity while avoiding feedback.
Ba Sao Audio deployed a 20.4-channel immersive sound system to deliver a fully three-dimensional sound experience, anchored by Flux:: SPAT Revolution to provide precise spatial positioning and real-time control of sound sources throughout the venue.
Vu said: “This collaboration has enabled us to create a powerful and engaging experience for audiences. Working with Harman’s integrated solutions allowed us to meet the technical demands of the production while supporting its creative goals.”
The immersive system was supported by 20 JBL AC18/95 loudspeakers for full-range coverage and four JBL STX818S subwoofers for low-frequency response. Crown CDi Drivecore 4|600 and MA9000i amplifiers handled power and system control while 49 AKG microphones, including the C214, C519M, C411PP and C451B models, were chosen for their ability to capture the detail and texture of traditional Vietnamese instruments. Mixing and routing were managed using a Soundcraft Vi2000 digital mixing console paired with a 64-channel Dante stagebox. System processing and spatial audio rendering were handled by BSS Soundweb BLU-806 and BLU-BOB2 processors.
Amar Subash, VP & GM, professional solutions, APAC, commented: “This project exemplifies how our end-to-end solutions can elevate cultural storytelling. CHÀO is a model for how immersive technologies can preserve and amplify tradition in a way that’s both modern and moving.”
