Chen Chusheng is a well-known singer in China. During his 2023-2024 China tour, GAODIMIC AT210PG series digital audio UHF wireless system was used throughout the entire tour to complete the sound field test and concert sound field monitoring.

Chen Chusheng's tour is themed "Edges". The constantly changing light and edges after filtering and projection show the different perceptions flowing deep in his heart, and his music is like each side reflected by a prism. The style is diverse and each side is equally colorful. Break through the original positioning and explore yourself in music, showing the unique musical edges of the gentle singer!

Chen Chusheng's "Ling" Tour Concert Tianjin Station

The sound design of Chen Chusheng's "Ling" Tour Concert revolves around the overall theme and creative concept of the performance, breaking the stereotyped template sound production logic, and using sound and music to show multiple "Ling" colors.

The well-known sound engineer Lin Zhemin served as the sound director and FOH mixer for this tour

In this FOH sound system, in addition to using conventional digital mixing consoles, more than 32 channels of external hardware devices are also used to add more "artistic colors" to the live music in mixing. All external hardware devices with analog interfaces are connected to the console through the DirectOut ANDIAMO ADDA interface box to ensure the restoration and purity of the sound signal in transmission as much as possible, and also to ensure that the equipment connection is simple and efficient. Among the external hardware devices, equipment from multiple brands such as SSL, Rupert Neve, Harrison, API, PULTEC, RETRO, Little Labs, and Maag were used. Through equipment with different performances, different sound content can be used to achieve different sound production goals.

Li Hong and Xing Kui from the Sound Harmony Team served as system engineers. This tour used d&b audiotechnik's J series and V series line array systems. The system engineer obtained the CAD data of each venue in advance, completed 3D modeling in d&b's Array Calc simulation software, preset the speakers in the corresponding positions, and checked whether the frequency response and sound pressure of each audience area can meet the performance requirements with small errors. This is the basis for modern professional sound system design.

During the on-site work stage, in order to ensure that the actual design is consistent with the model, and to start on-site measurement and correction of the system, usually 6 to 7 infinite spectrum measurement microphones are used for the size of the stadium, with the analyzer software Smaart, to correct the frequency response of each group of speakers to each point one by one, and to align the time difference between different groups of speakers, and the phase alignment between the line array speakers and the subwoofer, etc. During the system calibration and rehearsal stages, system engineers can often be seen walking around the auditorium, testing the system's various parameters and actual listening experience.

In larger indoor venues, such as the stadiums in this tour, there will be acoustic problems that most simulation software cannot directly predict. For example, the audience close to the stage will hear the second sound bounced off the back wall of the venue, or the low-frequency reverberation length is too long, and the bass and bass have long tail sounds. This type of acoustic problem is mainly divided into two types: early reflection (ER=Early Refelection) and reverberation length (RT60).

Early reflection refers to the situation where the sound is bounced back to the front row by the back wall. In this regard, the system engineer said: "You can rely on experience to judge in advance and add delay compensation speakers on the upper floors in advance. The closer the system is to the audience to make up for the volume, the less likely it is to produce high-volume reflected sound. Or in the absence of delay speakers, separate the loop of the line array speakers hitting the wall to reduce the affected frequency, which can also achieve the effect of reducing early reflections." The problem of reverberation length is relatively difficult to have a direct solution. The reverberation length can almost only be determined by the overall building surface material design. It is obviously impractical to add a large area of sound-absorbing material to the wall to solve this problem. "So the method we use is to measure the reverberation length at each station while calibrating the system, and the system engineer will communicate this situation to the mixer, so that the mixer can find a way to compensate for this problem in the mixing content, such as using a tighter gate or EQ attenuation of some frequencies to offset the listening problem caused by excessive low-frequency reverberation." The engineering team said.
