The Largest Stage Tec NEXUS Network and 12 Mixing Consoles in Use in China
"CCTV has been one of Stage Tec's largest customers for audio consoles and NEXUS networks since 2007 and is very pleased with their reliability and redundancy capabilities, which are particularly important for live broadcasts," explains Zeng Dong, Managing Director of Stagetec Media Technology. "The audio quality and features of the mixing consoles are also convincing. And the possibilities offered by NEXUS in terms of network size and format conversion were clearly demonstrated at the celebrations marking China's 70th anniversary." For sound reinforcement and recording, a huge NEXUS network with three routers and 33 Base Devices as signal distributors was installed. The sounds of the various events were input via 592 TrueMatch microphone converters.
Powerful systems are needed for broadcasting major events, and the 12 consoles and I/O systems, which were distributed in four OB trucks and four sound studios, were well provisioned accordingly. Two UHD and one HD OB vans from CCTV were each equipped with two consoles: a 48-fader AURUS and a 12-fader ON AIR flex. The fourth OB truck belonged to the Communication University of China in Beijing, which had a 32-fader CRESCENDO console installed. The OB trucks were also equipped with large NEXUS I/O systems. Both UHD OB vans were equipped with 224 microphone inputs and up to 704 AES67 streams. In all four OB vans, individual programme sections of the all-day events were mixed, recorded and forwarded to studios.
Further signal processing and broadcasting of the events took place in four CCTV sound studios, where Stage Tec mixing consoles and NEXUS networks are also installed. Two 56-fader AURUS consoles broadcast the evening gala event from a recording studio. In a second studio, a 40-fader AURUS mixed various different parts of the programme, which were then streamed. In the third studio, the events were mixed and recorded during the day by a CRESCENDO with 56 faders, which were then broadcast throughout China. The mixing and recording of selected programme sections for international distribution was handled by a 40-fader CRESCENDO in the fourth recording studio.
