From June 9th to 10th, the much-anticipated 18th Meeting of the Council of Heads of Member States of the Shanghai Cooperation Organization was successfully held in Qingdao, Shandong. This was the first summit held after the expansion of the Shanghai Cooperation Organization and the second major home diplomatic event of the year following the Boao Forum for Asia. PCI Company, entrusted with a significant responsibility, once again successfully completed the audio system support task for this major international conference, using the Q-SYS™ network audio system processing platform as the core, following the Beijing APEC Meeting, Hangzhou G20 Summit, and Xiamen BRICS Summit.
Due to its powerful processing capability, simple and flexible system architecture, and stable and reliable operation, the Q-SYS™ system was once again chosen as the core audio system for this summit, responsible for the management, transmission, and control of audio signals. The summit had nearly 40 meeting areas, including 5 main venues, 25 listening points, and multiple bilateral and multilateral meeting rooms. The audio channels throughout the venue amounted to more than 400, with over 300 audio streams being transmitted and processed simultaneously during the summit. To meet such vast and complex audio processing needs, the Q-SYS Core1100 core processor stood out for its robust processing capabilities.
The Core1100 is tailor-made for large audio systems. Thanks to its IT-based hardware platform, it can achieve more than double the processing capacity without significantly increasing costs. It provides 256x256 low-latency network audio channels and 96 AEC processing channels, endowing the summit's audio system with powerful and stable processing capabilities.
The audio collection and distribution functions for the more than 40 meeting areas were completed by the Core510i and Core110f processors. Audio streams based on the AES67 standard were distributed to each listening point. According to the secrecy standards required on-site, the entire audio system was designed in a dual matrix mode, transmitting audio signals to corresponding listening points for different participating countries and content, allowing officials to eavesdrop on the conference content.
With the Q-SYS™ system's powerful software-based processing capabilities, staff in the central control room could monitor the working status of each device and even listen to the input and output signals of each terminal, allowing flexible routing and control of the system. This summit also posed extremely high demands on the stability of the conference system. The system design included a dual-main unit backup, consisting of two Core1100 core processors in a failover system, ensuring the stable operation of the entire audio system.
In addition to the outstanding performance of the Q-SYS™ system in audio transmission, the QSC KLA active line array speakers played a significant role as the main sound reinforcement system in the press conference hall during the summit. The KLA series is the line array product of the QSC K family of active speakers, and the global sales of the K family speakers have now exceeded 1,000,000 units!
