When Failure is not an Option
Tiananmen Square is a huge open space and although there is a public address system on site, it is not going to deliver broadcastable quality audio or even something that can be followed by the symphony orchestra of 1,028 musicians and a chorus of 100,000. All important audio cues such as the sound of the salute, the orchestra and chorus of 1,000 and other key elements of the event were recorded three months before in DXD using Merging’s Pyramix. This was then replayed live with the sound effects on Merging’s Ovation system in CUE mode. This allows the live sound to be mixed with the pre-recorded for a vastly improved listening experience. If this sounds simple, it is not. Several hundred cues have to be programmed in advance and adjusted during rehearsals.
Two Ovation MassCore systems were responsible for this task and at the same time there were two Pyramix MassCore systems recording 128 channels over a 3-hour period. Using the RAVENNA network and optical fiber, it is easy to have these systems backing each other up. As may be imagined, there were a lot of microphones on site spread over a large area that needed to be mixed into the 128 channels and multiple Horus and Hapi units looked after this task. Even the new Merging+Anubis found a role to play in this impressive system.
All this audio information was being captured in surround and fed back to CCTV’s studios. Engineers there used Lawo consoles to mix the multiple live feeds and manage the various delays caused by the distances involved. The final results were broadcast to the mobile phones, tablets and televisions of the huge Chinese audience all over the country watching the parade and the evening party with fireworks.
An event of this magnitude needs the benefit of talent and experience to make it run smoothly and this was certainly the case here. The leader of the team was Li Dakang, the most well-respected recording engineer in China and a professor at the China Media University in Beijing. Among those helping him were various students and protégés of his. Cao Meng is a professor at the China Music Conservatory, Fend Hayang is now General Manager of Genelec’s office in China and Zhang Li Yong. From a technical perspective, the Merging equipment was supported by Dreamula under the leadership of Zhu Jie. Also in attendance was Merging Asia’s President, Weishen Xu. A number of other experts were also recruited by Li Dakang to contribute expertise to other aspects of the installation.
There are other statistics that need to be understood. The military parade involved 15,000 marching personnel, 600 vehicles and 180 planes in the flypast. There were also 110,000 in the civil parade with 70 floats, multiple guns firing a 21 shot salute and the President taking the parade salute from a moving car. All the audio had to be intelligible to those present as well as the TV audience. The event was on a truly epic scale but with Ovation being the perfect playout device for this situation, Pyramix being the only reliable high-track count recording and editing solution and the full range of networked audio RAVENNA/AES67 converters, it is hardly a surprise that this memorable celebration has joined the long list of mission critical events that have been powered by Merging.
