Intelligent digital audio matrix and control method therefor

Abstract

The invention discloses an intelligent digital audio matrix and a control method therefor, and the audio matrix comprises a PC terminal, a main control module, an audio processing module and an audioconversion module, wherein the PC terminal and the main control module are in communication connection through a network, and the audio processing module is composed of several IO processing cards, wherein each IO processing card is connected with the main control module in a point-to-point mode. The audio processing module and the main control module are connected with each other through a CPCI interface. The invention adopts the advantages of the IC technology, network technology and digital signal processing technology, and has the advantages of small size, high efficiency, high speed, convenient operation, and high stability. The audio matrix can achieve the advantages of network monitoring. The audio matrix is provided with an analog audio interface, a digital audio interface and a network audio interface, so the audio matrix is suitable for various types of audio signals. In addition, the audio matrix can also perform audio mixing, equalization, gain and compression processing ofthe audio signals, so that the quality of the output audio signal is better.

Description

technical field [0001] The invention relates to an intelligent digital audio matrix and a control method thereof, belonging to the field of network and data communication. Background technique [0002] Audio matrix is ​​widely used in various sound reinforcement systems, such as conference system, professional performance audio system, public address system, etc. Traditional audio matrix generally uses large-scale analog switching devices for matrix control, which has simple functions, poor performance indicators, and circuit Complicated shortcomings. The audio transmission systems of early radio and television stations used dedicated audio cables to centrally transmit the analog audio signals to the mixer or jack plate for signal switching. The routing switching of this matrix consists of many cross-point electronic switching circuits. Under system configuration, by controlling the on-off of a certain cross point, the corresponding input channel and output channel will be...
