Professional Sound Sytsem Solutions for Multifunctional Hall

Solution Overview

Design Objectives

● In any corner of the function room, you will hear clear, bright, rounded, full, thick and powerful sounds.

● The equipment needs to be stable, reliable and easy to operate. There will be no frequent failure and interference.

Design Method

● According to the location of the multifunctional hall and its functions, we adopted the centralized + decentralized sound reinforcement. We set the design standard of the sound reinforcement system of the multifunctional hall (multi-purpose class) as the national first-class standard, that is, the average maximum sound pressure level needs to be 103dB, the steady-state sound field unevenness is 6-8dB, and the sound transmission gain is -8dB. The fluctuation of the transmission frequency characteristic curve does not exceed 4dB.

● We design audio sound reinforcement systems to meet and exceed national standards to reflect the superior performance of the system. The sound effect of the sound reinforcement system conforms to the above level I standard of both language and music in the acoustic characteristics index of the GYJ125 multifunctional hall sound reinforcement system design, and achieves clear language, no distortion, sufficient sound pressure margin, and uniform sound field distribution.

 500㎡-Multifunctional Hall Configuration Solution

● Pickup Part: We adopt the true diversity wireless handheld microphone, collar clip microphone and wired condenser microphone to ensure the speeches of speakers and leaders, at the same time, the antenna amplification system is equipped to ensure that the wireless signal will not appear cutoff frequency and crosstalk and other failures.

● Regulation and Control Part: The 8-channel mixing console and digital audio processor are selected to regulate the entire system. The analog mixer is simple to control and has sufficient functions. It has a variety of audio signal input and output interfaces, which can output multi-channel audio signals to meet the connection of various audio source inputs and outputs. The digital audio processor and feedback suppressor are built with rich peripheral modules, which can carry out various processing operations on the whole system while ensuring the signal-to-noise ratio and reducing the failure rate. It not only provides stable performance and diversified modes, but also supports hot-plug function. The failure of one channel will not cause other channels to be unavailable, enhancing the entire system’s stability.

● Sound Reinforcement Reduction System: It adopts 4+1 line array speakers and 2 line array full-range speakers as the main speakers, and the combination of woofer and full-range speakers allows for better sound and coverage. According to the venue, it is equipped with 4 stage monitor speakers and 4 apron stage speakers to fill the sound gap of the stage and front row audience. Four 350W two-way speakers are used to assist in supplementing the sound pressure level in the midfield; The entire system provides a more balanced sound without a frequency band being too prominent or insufficient, allowing listeners to hear a more natural, realistic sound. It also meets the national standards for average sound pressure level and sound field unevenness and is suitable for different performance activities.

● Central Control System: With central control host,  the power switch, volume level, screen switching, lighting, etc. can be controlled centrally on the wireless tablet PC to improve the operability of the meeting and create a high-tech intelligent conference room.

● System Protection: Mainly equipped with power sequence controller, in order to prevent the safety and reliability of the system equipment in use, especially in the event of an accident, but also to protect the equipment from damage.
