INDONESIA: From 3rd to 5th October, the Gambir Expo in Jakarta came alive once again with the pulsating sounds of the Synchronize Festival — one of Indonesia’s most eagerly awaited annual music events. Showcasing an eclectic mix of traditional, indie, and contemporary pop artists, the festival’s District Stage drew large crowds with standout performances from Efek Rumah Kaca, Barasuara, Bernadya, 2000s icons Kangen Band and Letto, and the highly anticipated Guruh Gipsy, whose intricate 96-channel blend of traditional and modern instruments made for one of the weekend’s most technically complex setups.

Tasked with delivering pristine sound across this dynamic stage, Jakarta-based DSS Rental deployed an all-NEXO loudspeaker system powered by a Yamaha RIVAGE PM7 digital mixing console, with technical support provided throughout by Yamaha Musik Indonesia Distributor (YMID).

The main system comprised a stereo line array system spotlighting 12 units of the GEO M12 line array modules per side, reinforced by 14 units of the MSUB18, 4 units of the RS18, and 4 units of the LS18 subwoofers. 6 units of the PS15R2 point source speakers handled front and side fill duties, ensuring full-range coverage across the performance area.

Operating in passive mode and driven by NEXO NXAMP Powered TD Controllers, the GEO M12 rig achieved exceptional clarity and uniform coverage, with the main arrays projecting cleanly to approximately 70 metres. Measurements taken at the Front of House position — located 35 metres from the stage — averaged between 98 and 103 dBA, delivering an impactful yet controlled sonic experience for both artists and audiences.

System design and tuning were led by Ahmad Yusuf Ardisasmita and Ryan Andriesyah, working closely with Edmonds Angkawijaya, Gabriel Gunawan, and Dwivaldo Desprialdi from YMID’s technical team to ensure optimal system performance throughout the three-day festival. Their detailed preparation and collaborative effort ensured that the NEXO system delivered a natural, powerful, and immersive sound field across the venue.

According to Ryan, NEXO’s NS-1 simulation software proved remarkably precise when compared with on-site measurements, requiring only minimal EQ adjustments to achieve the desired target curve. “The GEO M12 system proved its versatility, providing even coverage and natural sound reinforcement that met the demands of every act performing on the District Stage,” he affirmed.
