Line In
Line-in symbol. PC Guide color Light blue.
Line in expects the kind of voltage level and impedance that line out provides. Typically, the line out connector of one device can be connected with the line in of another. However, doing this with a straight cable directly connected to both devices and having both devices on AC power may cause a ground loop, although some devices provide isolation.
A line input has a high impedance of around 10 kΩ, as is often labeled as "Hi-Z" input (Z being the designator for impedance).

Famous quotes containing the word line:
“What is line? It is life. A line must live at each point along its course in such a way that the artist’s presence makes itself felt above that of the model.... With the writer, line takes precedence over form and content. It runs through the words he assembles. It strikes a continuous note unperceived by ear or eye. It is, in a way, the soul’s style, and if the line ceases to have a life of its own, if it only describes an arabesque, the soul is missing and the writing dies.”
—Jean Cocteau (1889–1963)
“There’s something like a line of gold thread running through a man’s words when he talks to his daughter, and gradually over the years it gets to be long enough for you pick up in your hands and weave into a cloth that feels like love itself. It’s another thing, though, to hold up that cloth for inspection.”
—John Gregory Brown (20th century)
