The performance scene adopts high-tech complex stage design, such as LED lifting module, water curtain imaging, holographic yarn, etc., and also includes various program forms such as ice and water projects. The environment of the performance venue is complex, how to use the AoIP system to deal with it easily?
With the theme of “Olympic City, Ice and Snow Invitation”, held at the Water Cube, the “four habitats stage” of water, land, air and ice staged an ice and snow fantasy show gathered by the world’s top artists. This audio-visual feast was recorded on December 18, 2016 and broadcast on Beijing TV on the evening of December 31.
In the system design, we have made a preliminary planning for the system from the early stage. and considered acoustically.
The front end of the audio system uses an almost all-digital approach. Including AES-3 and AoIP, we digitally connected everything with digital outputs to the mixer.
More and more wireless receivers use digital transmission or digital chips to process sound. If an analog audio cable is used to connect the signal from the wireless receiver to the digital mixer or interface box, it means that the digital signal inside the wireless receiver is First, it is converted into analog audio signal by D-A, and then A-D is converted into digital signal on the mixer or interface box. Such a process will not only introduce two D-A and A-D conversion noises, but also introduce analog transmission noise on the analog audio line, and the dynamic range of analog transmission is smaller than that of digital transmission, which will undoubtedly destroy the original characteristics of the sound. What you get on the mixer is not what the wireless receiver gets.
