Multimedia classroom system device configuration large screen projection system: Japan "SONY" high brightness multimedia projector, the well-known ", as the United States and good" high-gain projection screen electric spheres intelligent electronic device centralized control system: the well-known "SVS" intelligent central control system computer network system: high-performance sound reinforcement system configuration compatible computer: joint venture "SVS" combos and one with two wireless handheld microphones and other combined into a multimedia sound system. PA system should include the following sections: the acoustic signals into electrical signals of the microphone multimedia teaching equipment, amplifying electronic equipment, electrical transmission lines and signal processing of the processing power of the electric signals into acoustic signals the speaker and the audience area acoustic environment. The main technical indicators PA system: Specifications grade sound system shall be determined by knowing and Hubei University School of multimedia classroom use, category, area standards, service target and other factors. Acoustic characteristics of indicators audiovisual place sound system design requirements can be designed in the following table: Composition of the multimedia computer multimedia PC machine (MPC) explained in a multimedia computer before, the traditional personal computer or information processing machines is often limited to text and digital, can only be regarded as the initial stage of computer applications, and multimedia lecture hall, way due to the interaction between man and machine only through the keyboard and display multimedia classroom design, so the exchange of information, lack of diversity. In order to change human-computer interaction interface, enables the computer to set the sound, text, graphics, image processing in one, the invention of the computer has multimedia capabilities of multimedia classroom | Multimedia | Wuhan Wuhan Jiuhua Jiuhua video provided by the video Engineering Limited .
