Command Hall

The audio reinforcement system of the command center of this project adopts Soundking's latest independently developed surround-screen array speakers (the number of speakers reaches 28), specially tailored for the command center LED screen (pixel pitch 1.25mm, total area of 120 square meters), audio and video integration of the LED special surround-screen coaxial adjustable beam array audio system. After more than 5 years of research and development, testing and various high-intensity testing, Soundking has successfully completed the LED surround-screen surround-sound system solution, and won 10 international technology patents. LED special surround-screen coaxial adjustable beam audio system, become a combination of audio and video integration, the end of the LED screen in the market alone, to solve the technical problems of audio and video playback can not be synchronized, can not be integrated with the same frame. The speaker system technology is successfully put into use in the project of Liangshan State Emergency Command Center, with a number of significant industry innovations, filling the industry gaps at home and abroad, and won the praise of industry experts and owners during the project acceptance.

Innovation 1: the speaker and LED display to achieve the "same frame" - change the traditional speaker partition management, multi-point distribution of the layout, to achieve the sound of the scene without the cabinet, does not affect the original layout of the decoration, the overall appearance, neat, with a sense of technology, mystery;.

Innovation 2: audio and video signals achieve "synchronization" - sound and image synchronous transmission, all audio sources from the same direction, sound image overall consistency, sound and image synchronization and meet the direct sound technology requirements, beam horizontal coverage width angle of 90 °, vertical coverage angle can be freely adjusted between ± 45 °, electronic beam adjustable directivity technology, the perfect solution to the sound field coverage uneven and other issues.

Innovation 3: the speaker is concentrated on the "same plane " - sound field concentration control, with plane wave, beam adjustable algorithm, the same plane, accurate sound directivity, sound field distribution.

Innovation 4: sound broadcast with the “same plane” of the LED screen around - the use of plane wave acoustic design, changing the traditional audio sound reinforcement technology phase interference, reduce room reflection, reduce reverberation, improve the overall sound clarity, to achieve point, surface, array of integrated full coverage, to achieve sound waves adaptive technology.

Innovation 5: the entire command center using the "same specifications " of the speaker - speaker array to form a line of sound sources can make the sound wave radiation farther, high utilization of sound power, strong interoperability, high compatibility.

Innovation 6: each speaker installed " same kind " of 16 one inch, 8 four inch hi-fi speaker - each hi-fi speaker has 16 independent bandwidth amplifier DSP processing, the same specifications, the same model, digital DANTE signal, array of two-way coaxial design, HF transducer of high-frequency mixing frequency. There is no sound interference and there is no need to worry about meeting interruptions.

The above six "same" technology, composed of a new, professional, complete, independent, synchronous, perfect command center innovative sound reinforcement system, from the traditional "engineering to engineering" design model, and the use of "engineering to art" design concept, the perfect combination of technology and art, the combination of humane and technology, the maximum to meet the "humane" use needs, for the existing huge stock of market transformation and the development of emerging output has created an unpredictable bright market prospects.

As the core of the sound reinforcement system, the choice of mixer is particularly important. Soundking's British mixer brand Cadac has been the embodiment of high-quality audio mixing consoles, known as the mixer "Rolls-Royce". The use of the mixer is CADAC's CDC5 digital mixer, favored by many high-end art performance venues, such as the British National Theatre, Shanghai Grand Theatre, Hebei Arts Center, etc., but also for the APEC meeting in Beijing, Xiamen BRICS Summit, etc. to provide security. High-quality amplifier input and unique parameters of equalization, with similar mixers can not be compared to the outstanding sound quality and stability, good performance and compact size can easily cope with a variety of occasions.

Digital conference unit selected for the latest development of Soundking, repeatedly used in government meetings, digital-mode dual display, digital-mode dual backup digital conference system, using international patented technology, analog lines and hand-held lines dual pickup design, two lines completely independent, non-interference, mutual backup, super anti-mobile phone RF interference, to protect the high reliability of the meeting. High-sensitivity microphone core provides high-quality sound pickup; high-resolution capacitive touch screen can receive short messages and send commands to the backstage to achieve front and backstage communication; with sign-in, voting, scoring and other functions.

Paperless: high precision and confidentiality, efficient conference

Paperless conference system, optimize and transform the traditional conference process, reduce the use of paper documents through IT technology, and realize the basic functions of conference. For emergency rescue meetings of production safety and natural disasters, work meetings of major disasters headquarters, work meetings of fire, drought and flood disasters, geological disaster prevention and control meetings, etc., the paper-free electronic office system and a large amount of cloud storage space are provided. At the same time, the meeting can be emptied at the end of one-click to ensure the safety of the meeting and realize the double advantages of environmental protection and safety.

Conference recording: HD recording, record the excitement

Conference recording system, through the deployment of conference recording server to achieve the conference process of live broadcast, HD recording, scheduling and decision review, large-capacity storage and other functions. It supports multiple video formats input, solves the demand of recording and broadcasting with HD and SD video coexistence in conference rooms, and provides comprehensive recording and internal live sharing for emergency command center to prepare emergency plan planning meeting, disaster prevention and mitigation meeting, training meeting, etc.

60-person conference room

Audio amplification system The main amplifier uses a sound column system with high sound clarity. By switching the audio system, it can be used as a conference room alone, for video conferencing, and for audio interconnection with the command hall, as a branch office.
