The sound reinforcement system for a conference room is a precise and scientific system with high stability and reliability. It should be combined with the actual situation of the entire venue to achieve the desired effect.
Therefore, in the design of the conference room, we have fully considered the sound reinforcement requirements of music, conferences, reports, and speeches before adopting a digital conference system integrating concise and advanced processing technology control, and high-level transmission of language, music and video. The entire system can ensure the uniform sound pressure in the venue, and provide high-quality music and speech intelligibility.
Venue information as shown below:
Venue area: 15m in length, 8m in width, with an area of 120㎡.
Number of participants: 17.
Main purposes: exchange meetings, training, information release.
Main functions: display system, conference sound reinforcement, digital discussion system, simultaneous real-time display of multi-channel video signal/VGA/HDMI signal/composite video signal.
Digital conference system: It is composed of conference control host D6201, speaking mic D6221/D6222 and other related equipment to meet the requirements of conference functions such as speech and discussion of participants in each conference room. Configure the tracking camera D6283II. When a conference mic is turned on, the tracking camera will track the position of the speaker for close-up, and transmit the signal to the matrix or directly to the display device for viewing.
Video system: It is composed of 8-channel plug-in host D6108, 1 HDMI input card (4 channels), 1 HDMI output card (4 channels) to meet the needs of camera tracking, video playback, work report presentation, etc. in the meeting. The HDMI matrix forms a central signal management system for the signal processing part to achieve powerful signal switching, scheduling and other tasks.
Sound reinforcement and audio processing equipment: It is equipped with a MG12 mixer for audio access in the meeting room. In addition, D6643 is used as a professional audio processing equipment to make the voice clear, distortion-free and no feedback howling, 6 full-range wall mount array speakers D6072B and 2 12" woofers D6073B are used in the conference room to meet the sound field requirements of the venue, and 4 dual-channel amplifiers are used to promote sufficient on-site sound pressure margin, uniform sound field, accurate sound image positioning, etc.
Solution Highlight Functions
System Connection Diagram
1. Sound reinforcement system
In terms of sound reinforcement, it focuses on the clarity of speech sound reinforcement, sound transmission gain, sound pressure level, sound field uniformity, and music playback sound quality, which can be achieved through digital audio processing. The whole system is mainly composed of conference system D6201, video matrix equipment D6108 and professional sound reinforcement system equipment. Among them, the audio sound reinforcement system is mainly composed of speakers, power amplifiers, mixers, microphones, audio sources and other equipment, which can realize simple meetings, speeches, special topic seminars and others.
2. Conference speech and discussion function
The chairman unit has the priority to speak, which supports four conference speech modes: FIFO mode, NORMAL mode, FREE mode, and APPLY mode.
3. Video signal processing function
It adopts a 120" projection screen, an engineering projector with a brightness of 6500lux, a camera D6283II and other display devices to realize the coordination, processing, and switching of input and output signals. The input signal can be switched and combined at will for a flexible central signal processing function.
4. PC and mobile phone control function
It supports TCP/IP protocol, and all functions of the system can be remotely controlled through the PC software and mobile phone software for the efficiency of the system.
5. Speech timing and system recording function
The administrator/secretary sets the display of a certain unit to display the speaking time (the speaking time of the microphone, which can be used as a timing reminder). Plug a USB flash disk into the host D6201 to record the whole conference audio for later archiving.
6. Audio and video switching system
The D6108 video matrix system can switch any camera video signals, video conference terminal signals, computer signals of information points, and various types of external signals to the corresponding display terminals as needed to ensure the orderly progress of the conference. It adopts a matrix signal switcher with flexible configuration, high-performance hardware, without black screen and crack during the switching process, to perfectly support various high-definition digital/analog signal switching processing. Combined with wiring engineering to embed various cables in the conference room, the matrix in the system is equipped with high-definition cables to achieve lossless signal transmission, ensure signal transmission quality, and improve transmission distance; as well as achieve seamless connection, conversion, switching, and transmission of various video signal sources in the system, and centralized and unified management of all information access points and other signal sources in the conference room.
