Multimedia teaching system functions, with the continuous development of modern methods of teaching and training, a modern multimedia classroom in addition to the traditional simple meet teaching requirements, it must also have a beautiful sound, clear image presentation. It shows the large-screen projection, multimedia audio and video sources, audio, central switching and integrated control of several major components. Select with advanced features and DVD recorders and Real Video Showcase restore its image through the LCD screen splicing BC46AA-03 series of products, in order to be more efficient, real-time operational needs with a central control system (BC -DPRO913), all audio and video control room equipment, signal switching, screen movements, volume adjustment and so on, greatly improve teaching efficiency and simplify complex operations, suitable for all teachers to use without the need to have expertise.

       According to the needs in this area and our practical experience, we will be meeting the entire system into several subsystems.

A large screen display system

       Second, the meeting PA system

       Establish an audio environment is inseparable from the electro-acoustic device, which consists of the following three parts:

Sound source equipment - pickup equipment, audio and video signal playback device such as: Microphones (wireless microphone, wired microphone), CD, VCD or DVD and other equipment;

Amplifying device - through the regulation refers to equipment mix output signal after signal processing post-stage power amplifier device, in this case a power amplifier;

Reproducing equipment - through the power amplifier amplifies the audio signal electric - acoustic conversion and release manifested an audible audio signal device, in this case the speaker; the central integrated control systemic

As technology advances, the majority of customers for a variety of multimedia classrooms raised higher and higher requirements; advanced audio and video equipment, electronic equipment, etc. are used in many demanding customers, in order to achieve the desired effect. But as the number of devices increases, more and more remote control, the control method will be more and more, as people know what to do; at the same time to control the environment, it is difficult to change in a timely manner as needed to achieve the desired effect.

       Automatic intelligent central integrated control system can control all electrical equipment by touch keypad or computer software. You can control all electronic equipment in the classroom by a computer with video surveillance, including the projector, screen, lift, audio-visual equipment, signal switching, and volume adjustments. Chinese interface simple and clear, just hand touch on the control panel on the corresponding button, the system will help you achieve what you want to function, it can not only control DVD, video playback, fast forward, rewind, pause, selections and other functions, and you can control the switch, the switching signal, as well as the rise of the projector screen, down, etc. functions, eliminating the need for complex and extensive number of remote control.
