Longgang Children's Park is located on the north side of the intersection of Yanlong Avenue and Aixin Road, Longgang District, Shenzhen. It covers an area of about 320,000 square meters and is located in a U-shaped forest valley with beautiful natural environment. As the largest children's park in Shenzhen, it anchors the goal of "international standards and domestic first-class", and will build a Greater Bay Area that is "based on the mountains, ecologically integrated, IP empowered, leading public welfare, close to nature, and entertaining" The benchmark for child-friendly parks.
As one of the four core buildings in the park, the Comprehensive Service Center contains a forest theater with more than 260 seats, providing visitors with rich stage performances and immersive holographic sound and light animation experiences. It aims to bring interactive viewing effects that perfectly integrate hearing and vision to the young children who come to play, making them immersed in it.
The Forest Theater uses holographic projection for visual presentation. In order to create an integrated audio-visual and synchronous auditory effect experience, the sound design team specially used 30 small-sized coaxial speakers UT-06 from MotiVity, 10 each on the left, right and rear. In conjunction with the main amplification system, it is designed as a four-sided immersive sound system.
The UT-06 coaxial speaker, with its coaxial sound emission characteristics of the high and low frequency units, can more realistically simulate the sound characteristics of natural sound sources, and there will be almost no phase problems in the high and low frequency connecting frequency bands. Different from traditional point-source speakers with separate tweeter and bass units, the coaxial design (which saves space for the tweeter) also brings unique advantages in volume to this immersive live application.
"The speakers can be hidden as much as possible so that the picture can be as immersive as possible," said Mr. Gou Qi, IMMERSHOW brand manager and EVIM technical consultant.
In the design of the main sound reinforcement system, taking into account the surround feeling of the immersive sound system and the operability of sound and image control for live performances, the design team chose a left-center-right layout, leaving it to the scene. The mixer's different sound images create space and possibilities.
The three sets of main amplification loudspeaker groups are also responsible for the sound source playback of the main performances, conferences, and activities in the stage area. MotiVity's dual 8-inch full-range array SLA208 with super live sound quality performance is used. Each group has 4 hanging installations. Above the main stage entrance, there are a total of 6 SLA subwoofers SLA10-18B of the same series (2 units in a group), which are also embedded under the stage entrance according to the layout of left, center and right.
We believe that as the sound source moves with the sound image, its low-frequency energy distribution changes must also be felt, and this is indeed the effect.
In order to reduce the line resistance and power loss caused by long-distance wiring, the design team specially designed two audio machine rooms for the main and control rooms, which are located in the back area of the stage and the main control machine room.
All sound sources for stage performances and signal distribution of the main system and return system are completed in the power amplifier room behind the stage, while all speaker amplification of the control section and surround section are returned to the master control room for unified management.
The Stride network audio transmission and processing system is used to realize the distributed system data optimization of all audio equipment.
The core of immersive sound computing and broadcast control comes from the IMMERSHOW immersive show control system. The IMMERSHOW system is a sound-light-electric linkage master control system with music playback logic programming as the core line, developed specifically for live performances, outdoor light and shadow shows, indoor shows, cultural tourism night tours, theme parks, exhibitions, etc. .
IMMERSHOW® can edit different playback methods such as multi-track synchronization, multi-track asynchronous, single-track multicast, and multi-site terminal simulcast according to the needs of different performing arts forms. Users only need to log in to the iPad control interface to achieve one-click performance management, and even Automatic triggering, timed triggering, etc. are used as needed to achieve an unattended, fully intelligent performance experience.
According to the program format requirements of the main creative team, the IMMERSHOW design team cooperated with them to create four application scenarios of spring, summer, autumn and winter. The program broadcast content will change according to the changes of the current season.
In each scene, there will be corresponding sound effects, such as the chirping of birds in spring, the chirping of cicadas in summer, the rustling of fallen leaves in autumn, and the sound of howling wind and snow in winter, which make the sound immersive. These different special effects sounds may appear faintly at a specific location against the backdrop of background music, or may move with the holographic projection screen.
In the opening film of a children's drama, what kind of sound effects appear at what time and where, how to synchronize with the picture, and how to synchronize with the lighting test the rigor of the backstage source broadcast control logic, and what scene is before the show starts. , where to jump after the show is over, these are the interpretation and application of IMMERSHOW system in Longgang Children's Park Forest Theater.
After careful sound data measurement and optimization calibration, as well as linkage and running-in with various professional systems, Longgang Children's Park Forest Theater has successfully completed the production of its immersive program content. We look forward to the official opening of the park and bringing richer entertainment to children. Repertoire performance.
