Shanghai’s National Exhibition and Convention Center upgrades audio with Harman

Shanghai ACE, a branch of ACE International, has installed an end-to-end Harman Professional Solutions networked audio system at the National Exhibition and Convention Center (NECC) complex. The upgrade was part of extensive renovations in preparation for the inaugural China International Import Expo, an international trade fair proposed by Chinese President Xi Jinping.

To cover the entire complex sound, Shanghai ACE installed a wide range of JBL loudspeakers suited to different roles. The main sound systems in the exhibition halls comprise VRX and VTX series line array elements. Additional sound reinforcement is provided by JBL AM series loudspeakers. LSR series nearfield monitors provide sound for mixing and reference. For outdoor sound reinforcement, Shanghai ACE provided JBL EON 600 portable PA systems with Bluetooth connectivity.

To power the NECC’s sound system, Shanghai ACE provided 36 network-connected Crown I-Tech amplifiers and 26 DCi series models. Shanghai ACE also installed dbx loudspeaker management systems throughout the facility.

The entire system is connected by a network of BSS BLU-800 and BLU-100 signal processors, which perform signal routing via CobraNet and Dante protocols. A total of 18 Soundcraft mixers allow sound professionals to mix audio for large-scale events.

A spokesperson from Shanghai ACE commented: “Due to the rigid security of state leader conferences, there were strict requirements for the renovation project of the National Exhibition and Convention Center. We designed the Harman audio system to meet the toughest standards with excellent performance and high flexibility. Following the China Import Expo show, this audio system will continue to deliver premium audio quality for many more large-scale conferences and exhibitions.”
