Professional audio system - Multi-function hall solution

The multi-function hall is mainly used to hold large and medium-sized meetings, as well as small and medium-sized artistic performances of various nature, and its sound reinforcement equipment meets the sound reinforcement requirements of various activities from the use of functions. In terms of audience listening, the sound quality of the auditorium mainly includes clear language, bright high frequency, powerful medium frequency and rich low frequency of the music, distinct levels of music, appropriate loudness and uniformity in all parts of the auditorium, high sound transmission gain in the sound reinforcement system, and the sound image of the sound reinforcement system and the performance of the stage should not have defects such as echo and sound focusing in any position without the audience. These indicators indicate the overall effect of auditorium acoustics. Therefore, we redesign the scheme and equipment selection to meet the use of versatility and meet the audio quality. The original intention of the redesign is to combine the use of functions and listening indicators to select materials;

1, sound quality optimization: sound quality as the core of the design. To achieve this goal must be the selection of equipment as the first condition, we choose here are high-fidelity products, and equipped with advanced and reasonable system design, to ensure the optimization of sound quality.

2, advanced: in the rapid development of science and technology today, the development of electro-acoustic technology is changing with each passing day, and the replacement of electro-acoustic system equipment can not be the same; At present, in the period of alternating development of analog equipment and digital equipment, new technologies and new equipment continue to appear. In order to make the system design scheme more perfect, the sound quality effect is more perfect, in the design of sound reinforcement system, its scheme must have a certain far-sightedness while ensuring practicability.

3, reliability: The system must be able to operate reliably. We apply mature and reliable products here, and reserve more power reserves.

4, humanization: Our audio system fully considers the user's requirements for the use of audio, colleagues to provide a variety of functions. Input and output port diversified design, can meet the requirements of different users.

5, scalability: Reserve a variety of lines and interfaces to facilitate future system upgrade, flexible increase system equipment.

6, practicality: In addition to meeting the functional requirements, the sound reinforcement system also has the characteristics of simple operation and easy maintenance.

7, consistency: sound reinforcement system requires that the selection of equipment should follow the principle of consistent technical indicators.

8, economy: sound reinforcement system requires a good cost performance, practical and not exaggerated, high-grade and not extravagant

In the design scheme, full consideration is given to the functional requirements of the Office and its use.

1. Design content: According to the use requirements of this multi-function hall for meeting and performing arts. I want to make the main sound reinforcement of the multi-function hall and the stage return sound reinforcement meet the sound quality and functional requirements of the multi-function performing arts and important conferences.

2, design basis: Since the multi-function hall needs to take into account the needs of holding various meetings and entertainment performances, we refer to the relevant national standard in the design of the sound system - the music/language dual sound reinforcement system level I standard stipulated in "GYJ25-86, the performance characteristic index of the Hall sound reinforcement system of the Ministry of Radio, Film and Television of the People's Republic of China".

The sound reinforcement system should have the following functions:

◆ It should meet the functions of holding meetings, lectures and comprehensive cultural and entertainment performances.

◆ The system has a stereo sound reinforcement mode, which must be able to cover the entire audience area.

◆ The sound pressure distribution in the listener area is uniform, and the system should have a satisfied sound amplification gain before feedback.

◆ The practicability, safety and stability of the system should be fully considered.

◆ The hall can amplify the sound source has digital conference microphone, wireless microphone and multi-function information audio interface;

◆ Large screen display, with high definition, high brightness, realistic display effect; 2 50-inch TVS are used as the backcourt video display;

◆ Computer images, camera images, etc. can be projected on the large screen, and the display switching control of the large screen is completed by the wireless touch screen of the central control system;

◆ Two multifunctional sockets are arranged in this hall, which can easily access the laptop to the network, and display the screen of the computer through the large screen;

◆ The hall is equipped with a central control system. The audio and video display equipment in the conference room can be controlled through the wireless touch screen of IPAD, and the equipment that needs to be controlled in the conference room can be remotely controlled through the IP network.

◆ Power management and control of AV equipment can be achieved through touch screen;

◆ Can control the dial-up, disconnection and video switching of the video conference terminal;

◆ The switch of display signal can be controlled by touch screen;
