The difference between AV matrix and VGA matrix

The AV matrix switcher is a switching device for the audio to synchronize the composite video signal, ie, an audio and video switcher. Its input and output interfaces are standard BNC or RCA interfaces, and audio and composite video signals can be switched to the audio system and display device at the signal output terminal by software control, panel buttons, and remote control.

AV matrix switcher

AV matrix switchers can be widely used in large-screen projection display engineering, audio-visual teaching, command and control centers, multimedia conference rooms and other occasions. The traditional AV matrix is ​​analog signals. In recent years, with the continuous development of the market and demand, the digital matrix has been Began to use a large number of applications and more and more projects, digital matrix is ​​divided into DVI digital matrix, HDMI high-definition matrix. Among them DVI can't transmit audio, HDMI can transmit audio.

The VGA matrix switcher is specifically designed for switching and distributing computer monitor signals. It can switch multiple channels from the input channel to any channel in the output channel, and the output channels are independent of each other. In simple terms, it is possible to display any of the incoming multiple input signals to any one of the displays you specify. The “matrix” itself is a mathematical concept. It is an abbreviation for electronic products in the electronics industry. The name is "matrix switcher." The word "matrix" in the matrix switcher refers to the concept of matrix in advanced linear algebra. Specific to the matrix switcher in this electronic product, generally refers to multiple output options in the case of multiple inputs to form a matrix structure. In production and life, the wisdom of the broad working people is strong, so it is abbreviated as a "matrix."

VGA matrix switcher

In general, a matrix switcher is a type of device that switches input and output of multiple signals. In a general sense, the matrix switcher actually transmits one or more audio and video signals to one or more display devices. For example, two computer hosts share a single display, and the matrix switcher can use two computer hosts. Content is arbitrarily switched to the same monitor or multiple monitors. Matrix switcher, according to the signal source can be divided into: VGA, AV, DVI matrix switcher and so on. At present, the main application of matrix switcher is large screen splicing, video conference engineering, audio and video engineering, monitoring, etc., which need to use multi-channel audio and video signals to alternately use the project.
