This article mainly introduces what the line out interface means, it has a certain reference value, interested friends can refer to it, I hope you can learn a lot after reading this article, let the editor take you to understand it.

The line out interface outputs the analog signal processed by the sound card to audio devices such as speakers through the Line Out interface, and most of the sound output through Lineout can not control the volume through the machine itself.

Line out is to output the analog signal processed by the sound card to audio devices such as speakers through Line Out interface.

When Lineout first appeared, it was the output port of the transplanted desktop, purely for the purpose of external power amplifier and other sound amplification devices, so the raw data output by Lineout has not been filtered or rarely filtered by the chip, so the fidelity of sound is high.

But most of the sound output through Lineout cannot be controlled by the machine itself.

The impedance of the Lineout output is about 300ohm. If you connect it with a low impedance headset, you will feel that the sound is not full, full and inelastic. If you switch to a headset with high impedance, it is more full and transparent, although the sound is not loud. Generally, the output current is relatively small and will not cause overload.

Thank you for reading this article carefully. I hope the article "what is the meaning of line out interface" shared by the editor will be helpful to everyone? at the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
