Abstract

The invention discloses a controller of an audio and video media center system. The controller comprises a master control circuit, a logic gate control circuit, an audio and video input switching circuit, an input interface group, a video output interface, a balanced control amplification output circuit, a reverberation circuit, a frequency indicating circuit, a mode indicating circuit, a microphone input circuit and a power supply. The master control circuit is connected with the logic gate control circuit. The logic gate control circuit is connected with the audio and video input switching circuit and the mode indicating circuit. The audio and video input switching circuit is connected with the input interface group, the video output interface and the balanced control amplification output circuit. The balanced control amplification output circuit is connected with the reverberation circuit and the frequency indicating circuit. The reverberation circuit is connected with the microphone input circuit. The provided controller is advantageous in that the controller can control each device in an audio and video media center system at the same time, switching of control through line change is not needed, operation is simple, and function switching is easy.

Description

technical field [0001] The invention relates to a controller, in particular to a controller of an audio-video media center system. Background technique [0002] Existing audio and video media center systems generally include audio equipment, video equipment, and sound reinforcement equipment. In order to realize the use and switching of functions such as audio playback, video playback, and sound reinforcement, at present, multiple controllers are set in the audio-video media center system to control these devices separately, which leads to the following problems: When switching between the various controllers , The input and output of the signal are switched and controlled by changing the line, the operation is complicated, the function switching is error-prone, and the connection time is long. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a controller of the audio-video media center system, which can simultan...
