Theatre Concert Hall Conference Sound System Solution


Theatre music multimedia conference sound reinforcement system-scheme construction


System Overview:
Driven by the background of the times, the theater music multimedia conference sound reinforcement system integrates advanced audio and video processing technology, wireless technology and interactive functions to achieve high-quality, flexible and convenient music performance and conference experience. The application of these innovative technologies and features not only enhances the audience and speaker experience, but also promotes the development of the theater music and conference industry.
In order to ensure the best effect of the whole system, reliable and stable operation, the system design adopts advanced, mature and practical mainstream technology. It can realize various functions such as large, medium and small international conferences, general conferences, entertainment performances, multimedia screenings, reports, training, lectures, conference synchronization records, intelligent centralized control, etc.


Demand analysis:
The fullness of the sound: fullness refers to the enhancement and contrast effect of the direct sound due to the reflection of each interface when listening to the sound in the hall. An acoustically designed hall should feel thick, round, warm and elastic, with a sense of intimacy. Therefore, we strive to make the electric sound reinforcement system of the multi-function hall work in the full field, from the acoustic point of view, it should have sufficient loudness and brightness, medium and high frequency sound is appropriate, bright but not stinging, medium and low frequency energy is sufficient, and the transient response is good. What a great.
The bright and clear sound: the bright and clear sound mainly refers to the high-frequency components in the sound, and the attenuation is slow, and there are rich high-order harmonics. This is of great help to the expression of language and the level of music, giving the audience a feeling of clarity and transparency, just like a Tan Qingshui, looking to the end. What a great.
Sound energy distribution is uniform: the sound energy distribution of each point in the whole hall is uniform, that is, the sound field is evenly distributed, which can ensure that the loudness of the audience in each area is basically the same. In the hall with uniform sound field, the difference between the maximum sound pressure level and the minimum sound pressure level shall not exceed 6dB, and the difference between the maximum sound pressure level (or the minimum sound pressure level) and the average sound pressure level shall not exceed 3dB. In the sound quality design, the following measures can be taken to make the sound fully diffused, and the sound energy distribution is relatively uniform. And so much.
Appropriate reverberation time: the quality of the hall is very close to the reverberation time. Choosing the right reverberation time can improve the clarity of speech and the fullness of timbre. The near-reflection sound helps to strengthen the direct sound, especially the reflection sound from the side wall in the hall, which plays an important role in the sense of space and the sense of the sound. In large halls, near-subreflection sound can be used to make the sound field uniform. And so much.
Control of noise and feedback: in the design of the hall sound reinforcement system, the most headache is the background noise of the system and the feedback feedback of the microphone. In terms of sound construction, as the target place is irregular cuboid, it is easy to form the generation condition of simple standing wave. Therefore, we suggest that the owner should fully consider the design of sound construction materials and use surface decorations with appropriate sound absorption coefficient when decorating the hall, in order to obtain moderate early reflection sound, avoid harmful reflection sound, and reduce the sound field conditions of acoustic feedback.

 

Design ideas:
Equipment selection is based on the principles of international advanced, economically reasonable, safe and reliable use, convenient and fast maintenance. Ensure a good on-site sound reinforcement effect, ensure that the venue has a higher clarity, and provide more, more convenient and reliable expressions for the participants. We design the whole system with the idea of practicality, convenience, diversity, advancement, scalability, openness and security.
• Practicality:
To the maximum extent to meet the requirements of the actual work, to meet the user's business management as the first element of consideration, the use of centralized management and control mode. According to the actual needs to design the corresponding system, on the basis of meeting the functional requirements and technical indicators as far as possible to simplify the design, adhere to the practical, fully meet the needs of users.
• Expanding, maintainability:
To reserve space for the future upgrade of the system, system maintenance is the largest proportion of the entire system life cycle. It is necessary to fully consider the reasonable and standardized structural design. The maintenance of the system can be completed in a very short time. The project should have a good overall audio-visual effect, appropriate style and style, all products should be selected from domestic and foreign regular manufacturers, and accompanied by a product certificate.
• Economy:
Under the premise of ensuring the advanced, reliable and high performance price ratio of the system, the most economical goal is achieved by optimizing the design.
• Forward-looking technology:
Considering the future status of the system, forward-looking technologies and systems should be used in the design. The system structure is advanced, open system structure and the use of scientific system, the whole system can reflect the development level of today's sound reinforcement equipment.
• Availability and flexibility of system equipment:
It can meet the requirements of actual work to the greatest extent, consider meeting the owner's management as the first element, adopt the mode of centralized management and control, and meet the functional requirements on the basis of convenient operation, simple maintenance and simple management. Pursue the best investment effect ratio of less investment under the premise of satisfying the function.

 

Functional advantages:
-The speaker/performer's voice is amplified with high fidelity and clarity through the sound system to meet the standards and requirements of the sound pressure level for conference room meetings or hall performances;
• Through the LED display system, the speaker/performer's picture can be sent to the LED screen, so that everyone can see the venue;
• Stage lighting to meet the stage performance effect, according to different performances, showing different lighting effects, to meet the diverse needs of the venue.
• The central control system can realize matrix switching, power management, DVD player control, electric curtain control, air conditioning control, etc. It can manage all video and audio systems conveniently and quickly, so that the whole system can be managed conveniently and quickly;

 

Application effect:

Conferences and seminars: The theater concert hall can be used as a venue for large conferences and seminars, and the multimedia conference system can provide audio and video transmission and display functions to meet the communication and exchange needs of participants.
Academic lectures and lectures: The theater concert hall can hold academic lectures and lecture activities, and the multimedia conference system can be used for speakers to display research results, play audio and video materials, and interact with audiences.
Concerts and music education: The theater's concert hall can conduct concerts and music education activities, and the multimedia conference system can be used for live music playback and demonstrations, as well as providing interactive learning and educational content.
Corporate activities and celebrations: The theater concert hall can be used as a venue for corporate activities and celebrations. The multimedia conference system can provide audio and video playback, demonstrate company achievements and promotional materials, and realize interaction and communication with participants.
