II. function description
Function room equipped with professional sound reinforcement systems, advanced multimedia display system, rich in stage lighting lighting system and intelligent control system, to convene conferences, academic reports, watch movies, organised activities such as small and medium-sized theatrical performances provide excellent sound effects, clear screen display as well as simple and convenient centralized control.
In the function room of sound reinforcement systems, can be divided into conference system and sound reinforcement systems in two parts.
Conference system may have to speak, vote, simultaneous interpretation, and so popular in modern Conference and function. To speak of seats according to the scale of one¡¯s, up to several hundred people involved in the implementation of large-scale meetings. At the same time, the Conference system also has multiple statement mode, such as: first things first, way down the line is a plus, the President sole control, timing discussions, brainstorming, sound control, manual, etc., to provide more convenient for the participants of the meeting. Vote on features you only need to press to select, you can easily implement the voting results of the current statistics, shows, etc. for meeting efficiency greatly improved. Simultaneous interpretation system usually uses the wireless transmission mode, the maximum number of simultaneous translation in dozens of different languages, enabling hundreds of wireless viewing system.
The Conference system may also be additional video tracking, remote video conferencing feature will be meeting in the process of the sound and picture perfect combination. Video track is the use of camera and Conference system linkage, when he opened the floor microphones, the camera will automatically track the location of the speaker, and the picture is sent to the display device. Remote video conferencing through network technology and the related personnel in offsite news video conference discussions.
Sound reinforcement system within the multipurpose hall for playing movies, theatrical performances, good sound effects. Typically the size according to the size of the Hall, the function needs to choose a dozen or even dozens of speakers make amplification. In addition, the system should also include wired microphone, wireless microphone, DVD player, and other audio sources equipment and mixer, digital audio processor, equalizer, effects and control, handling equipment, according to the functional requirements of the appropriate function rooms.
If additional karaoke song VOD system, you can make the function room of richer entertainment features. If you make the entire system function better, you can also add related audio, video, and other devices.
Multi-purpose hall in video display systems are usually combined with the electric lift projector screen to achieve, in a movie or show other video information, lowering movements projector and electric projection screen to display the picture. In many such Auditorium will adopt hanging plasma TV to display video information.
From a technical perspective, multi-function Hall of systems in the design and construction has a certain complexity, especially on the user side of use also has certain technical requirements, this would require a technology to integrated management of the different features of the A/V equipment to coordinate work, this technology is the intelligent control technology. It can be controlled via the touchscreen to lighting, audio, and video display equipment, usage of the function rooms provide a more convenient way to manipulate.
Function room lighting, in addition to the daily needs of lighting, you can also add some appropriate, stage lighting as a theatrical performance increase and dazzling visual effects.

III. programme design
1. the Conference discuss the system
1) discussion system is a set of full-digital conference system, the entire system is used in all cables are connected, the hand-build, debug, the system is very simple. Conference system control host can be a variety of system preferences, including session mode, the venue layout settings, etc.
2) microphone unit has LED display screen, graphics and text will be unit settings and operation intuitive expression to the consumer. Separate floor units have different working patterns, through speaking unit setting, you can speak in different cell types (President, on behalf of the machine) to switch to change cell applications.
3) with smart IC cards, you can set the attendee information is stored in the card, you can also set up a separate unit of inventory, simply insert a floor unit with IC card, unit will automatically read the card settings information, set itself.
4) Chinese software interface, any of the four Conference mode options, including: brainstorming mode, automatic mode, timing discussion discussed model, the President sole control mode. Through the software's settings, you can achieve unit management, IC card information settings, session mode settings, audio settings, agenda setting,microphone grouping output function.
2, the Conference voting system
Adoption of conference management software meeting to vote on the software can achieve the Conference voting feature. Conference administrator through management software on the venue for this interface to set up a management that do not appear in the Conference Hall of the projection screen or other display device and the venue display interface, you can be the outcome of the agenda is the interface or interface, convenient use of the administrator and will not affect the participants of the Visual senses.
3. simultaneous interpretation system
In this simultaneous interpretation system uses a wireless digital UHF transmission technology, which uses double encryption technology means that the maximum guarantee of confidentiality and the stability of the system. Voice restoration and clarity with digital system mostHigh standard. RCF wireless technology uses a unique algorithm of dual antenna (multiple) manner, ensuring that transmission signal ideal and interference-free. The system can provide up to 10 languages for simultaneous interpretation.
4. camera with integrated system
Adoption of conference management software video tracking management software can implement video tracking capabilities. Automatic tracking of the so-called video is meeting system through the PC and camera connectivity, use video tracking software to adjust the camera's prefabricated, and store it. Again, when you press the microphone to speak the key, the camera will automatically track the location of the speakers and screen display to the venue of the projection screen or other display device. The system supports single or multiple cameras for video tracking.
5. video conference system
The system is configured with a supported remote video conferencing equipment.
6, conference recording system
System configured in the machine, CD/MD deck machine, multitrack hard disk recorder for recordingaudio signal.
7, language, music, film and sound reinforcement systems
1) system is configured with a professional DVD player to play all kinds of media files.
2) system sources section 2 set of wired microphone, 2 sets of wireless handheld microphone, 2 sets of wireless led clip microphone and 2 sets of wireless headset microphone for sound reinforcement, speaking in mobile.
3) system is configured with a set of independent karaoke song VOD system, including the popular in various types of music, songs.
4) system is configured with a 1-24-channel microphone or line input, 4 way grouping output, 6-channel mixer, sent aid to meet the needs of such places, enter the number of output channels.
Sound reinforcement system uses 5) digital audio system processor control, speaker entirely by 1 8 into 8 out digital processor-controlled, these processors set output level controller, filter, parametric equalizer, Extender, delay, such as functions, processor parameter is set to enter the speaker manufacturer-supplied data, both the greatest degree guarantee speaker performance play and simplifies audio system of control and debugging, but also on different use functions scene programming and storage, according to the site usage may be called at any time.
6) in order to meet the functional needs of optimization Auditorium sound system, the system is also configured with a graphical equalizer feedback suppressor. While configuring a computer effects, in theatrical performances.
