Line level is the specified strength of an audio signal used to transmit analog sound between audio components such as CD and DVD players, TVs, audio amplifiers, and mixing consoles.
As opposed to line level, there are weaker audio signals, such as those from microphones and instrument pickups, and stronger signals, such as those used to drive headphones and loudspeakers. The strength of these various signals depends on the output voltage of the source device, along with its output impedance.

Famous quotes containing the words line and/or level:
“Where were you when I laid the foundation of the earth? Tell me, if you have understanding. Who determined its measurements—surely you know! Or who stretched the line upon it? On what were its bases sunk, or who laid its cornerstone when the morning stars sang together and all the heavenly beings shouted for joy?”
—Bible: Hebrew, Job 38:4 -7.
God, to Job.
“Those who profess contempt for men, and put them on a level with beasts, yet wish to be admired and believed by men, and contradict themselves by their own feelings—their nature, which is stronger than all, convincing them of the greatness of man more forcibly than reason convinces them of his baseness.”
—Blaise Pascal (1623–1662)
