Professional Sound System Solution for Indoor Stadiums

To ensure the audience can receive information from the referee during games, the system must have a high sound transmission gain. Typically, the auditorium around the stadium is higher than the competition terrain. Speakers are suspended under the canopy for zone sound reinforcement, taking advantage of the directional characteristics of the speaker system to ensure sufficient sound pressure level and speech intelligibility in the auditorium. To minimize the impact of noise, the sound pressure level generally needs to be around 100 dB.

Design Objective

The primary objective of a sound system for a sports field is to amplify the speaker's voice in real time so that it can be heard by the listener in the same acoustic environment.  A successful sound reinforcement system must be loud enough (sufficient sound gain) and clear enough (low percentage of speech consonant articulation loss), as well as evenly cover the audience without covering areas where there is no audience.

Design Approach

We utilize decentralized sound reinforcement based on the outdoor arrangement and function positioning to achieve uniformity of sound pressure in the venue's sound field. The DSPPA conference system supplier speaker is designed to use for playground performances during ordinary times, while also meeting sound pressure requirements and usage suggestions.

According to the national acoustic characteristic index standard for outdoor sound reinforcement system design, the maximum sound pressure level in the open field quasi-peak state: 125-4000Hz, with an average greater than or equal to 98dB.  Our audio sound reinforcement system not only meets but exceeds this national standard, reflecting the superior performance of our system.  The professional sound system's sound effect meets the first-level standard of language and music in the GYJ125 Acoustic Characteristic Index for Outdoor Sound Reinforcement System Design, achieving clear language, no distortion, sufficient sound pressure margin, and uniform sound field distribution.

Professional Sound System - Configuration Solution for Indoor Stadiums

● Pickup part: Our audio setup includes both a true diversity wireless handheld microphone and a wired condenser microphone to ensure clear event broadcasting and leader speeches. Additionally, we utilize an antenna amplification system to prevent wireless signal loss or crosstalk.

● Regulation and Control Part: The whole system is regulated and controlled through the use of a digital mixing console, digital audio matrix, and feedback suppressor. The digital mixing console is user-friendly yet multifunctional, with various audio signal input and output interfaces to allow for connection to mobile sound reinforcement systems, radio and television broadcasts, large screen systems, recording and calling systems, press release areas, and background broadcasting systems. The console enables operators to perform quick mixing operations and can be easily expanded for future system expansion. The digital audio matrix has built-in peripheral modules for a range of processing operations and supports

● DANTE transmission, eliminating the need for long-distance wiring and ensuring a high signal-to-noise ratio. The feedback suppressor significantly reduces the occurrence of on-site sound howling for optimal system performance.

● Sound Reinforcement Reduction System: Our system utilizes highly directional dual 10" line array speakers for decentralized sound reinforcement. The line array speakers provide high sound pressure levels and can be adjusted vertically to accommodate different listening surfaces. Each group is equipped with an 18" subwoofer to compensate for lower frequency limits. An 800W constant resistance professional speaker supplements sound in areas that cannot be covered by the line array speakers while a monitor speaker helps the operator better understand the sound source.

● System Protection: To ensure the safety and reliability of the system, especially in the event of accidents, protecting the devices from damage and we also have equipped the system with power sequence controllers.
