Line out意思

"Line out" is a term commonly used in audio technology to refer to an output connection that provides a signal that is suitable for driving another audio system or device. It is designed to deliver a strong, clear signal that can be used to connect to an amplifier, speakers, or another audio component.

The line out signal is typically a low-impedance signal, which means it can carry a lot of power without significant loss. This makes it ideal for sending audio signals over longer distances without the need for signal boosters or amplifiers.

In contrast, a "headphone out" or "line in" connection is designed to handle weaker signals and may not be able to drive another audio system as effectively as a line out connection.

You might find line out connections on a variety of audio devices, including computers, mixing consoles, and some portable media players. When using a line out connection, it's important to make sure that the input device can handle the level of the signal being sent, as line out signals can be quite strong and may need to be adjusted or attenuated to prevent distortion or damage to the receiving device.
