Line Out
Line-out symbol. PC Guide color Lime green.
The signal out or line out remains at a constant level, regardless of the current setting of the volume control. Recording equipment can be connected to line out without having to monitor it through the device's speaker, and without the loudness of the recording changing if the volume control setting of the device is modified whilst recording.
The impedance is around 100 Ω, the voltage can reach 2 volts peak-to-peak with levels referenced to -10 dBV (300 mV) at 10 kΩ, and frequency response of most modern equipment is advertised as 20 Hz - 20 000 Hz (although other factors influence frequency response).

Famous quotes containing the word line:
“A line in long array, where they wind betwixt green islands;
They take a serpentine course—their arms flash in the sun—hark to the musical clank;”
—Walt Whitman (1819–1892)
“The real dividing line between early childhood and middle childhood is not between the fifth year and the sixth year—it is more nearly when children are about seven or eight, moving on toward nine. Building the barrier at six has no psychological basis. It has come about only from the historic-economic-political fact that the age of six is when we provide schools for all.”
—James L. Hymes, Jr. (20th century)
