Large sports center

—— Luzhai Sports Park sound expansion system

Luzhai Sports Park in Liuzhou, Guangxi, is one of the major projects in Luzhai County, with a total construction area of 42,500 square meters, built in two phases. The national fitness center in the first phase has a total construction area of 2684.5 square meters, including 2 standard basketball courts, and various sports events such as basketball, air volleyball and badminton; the second phase has a total construction area of 42525.7 square meters, including 34670 square meters, 7855.7 square meters, mainly building natatorium, track and field field, gymnasium, commercial street, basement, AAA level tourist toilet, decoration, equipment purchase and installation, landscape greening etc.

The sound expansion system of Luzhai Sports Center is equipped with JSL professional audio equipment, including LA series array, GL series array, MH series power amplifier, audio processor, feedback suppressor, power timing device, wireless microphone and other products, to help Luzhai Sports Center to better carry forward the spirit of sports!

Track and field

The track and field field is 18,070 square meters, with a standard 400-meter track and an 11-a-side football field. The east and west stands can accommodate 10,000 spectators at the same time, and will be the home of the Luzhai Grand Games. The sound expansion requirements of track and field field are as follows:

1. The sports field is an outdoor space, with a large area and a large number of spectators. Focus on the uniformity of the speaker's sound field and sound pressure and the clarity of the long-distance sound.

2. Sound equipment should provide enough microphone and background music entrance to meet the sound expansion needs of holding large-scale sports events, leaders' speeches, speeches, report meetings, large-scale performances and other activities.

3. Sound system equipment should provide various options, such as volume adjustment, sound color beautification, effect enhancement, and sound field processing, so as to facilitate the tuning personnel to debug according to various types of activities.

4. Cooperate with different sports venues (grandstands), install speakers, to meet the requirements of long outdoor sound expansion range, uniform sound pressure coverage, high clarity, and avoid echo generation.

The whole sports field is mainly expanded to large-scale sports events, performances and celebrations. According to the characteristics of outdoor space and the positioning of the use function, using centralized sound expansion, using line array speakers, grouping multiple superposition ways installed in the platform (stand), facing the sound of the field. In this way, the field range is enough, to meet the front field to the back field to have a uniform and stable sound pressure level coverage, with the stability and high definition of the expanded sound quality.

Indoor swimming pool

The newly built indoor natatorium covers an area of 5,900 square meters, and has built two-storey stands that can accommodate 3,000 spectators, and has dressing rooms, washing rooms and other facilities to host high-level events. In addition, the natatorium also built a small pool for citizens of different age levels. To make the indoor swimming pool with good amplification sound quality, JSL team for its built to give priority to with LA series line array speaker amplification system, LA series line array large sound pressure level, uniform coverage, uniform diffusion, strong directivity, near volume difference, due to multiple line array speaker superposition effect, range is far, the front and the audience heard the volume is very close, avoid the front feel sound too loud to hear, fit the indoor swimming pool amplification requirements.

Basketball stadium

The new basketball stadium, measuring 4,960 square meters, has 3,000 seats, with plenty of space under the stands, and vents behind each seat, so spectators don't have to worry about sweating at the ball in the summer. The sound expansion requirements of the basketball gymnasium should mainly have the appropriate reverberation time, and have a certain early reflected sound, the sound field distribution is uniform, no echo and sound focus and other sound quality defects, and no noise interference. According to the acoustic line analysis of the body shape and building structure of the stadium, the space in the museum is relatively high, which is easy to have sound quality defects such as echo and tremor echo. The top sound absorption body and la series line array expansion sound built by the JSL team can bring shocking and synchronous audio-visual experience to the audience, and also meet its acoustic requirements and standards as a sports venue.

Assembling site

JSL engineers develop a number of technical solutions according to the different characteristics of the sports center venue building structure. From the selection and collocation of the speaker equipment to the system wiring installation, debugging and optimization of every detail, the JSL team tracked the construction, debugging, training and acceptance of the project, to ensure that the sound expansion system of Luzhai Sports Center is scientific, reasonable, accurate and reliable, showing the best effect of the sound expansion system of the sports center.

With professional and quality to provide customers with satisfactory service experience, is the unremitting pursuit of JSL!

After two months, the sound expansion system of Luzhai Sports Park was built and successfully accepted. A complete set of sports center expansion sound system scientific and reasonable, simple and practical operation, officially put into use, can boost the overall level of local sports facilities, better undertake city, county comprehensive mass sports events, and provincial, autonomous region level and even national individual sports events, Luzhai sports park expansion project perfectly ended.
