Line Level

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:

    Gascoigne, Ben Jonson, Greville, Raleigh, Donne,
    Poets who wrote great poems, one by one,
    And spaced by many years, each line an act
    Through which few labor, which no men retract.
    This passion is the scholar’s heritage,
    Yvor Winters (1900–1968)

    Ambivalence reaches the level of schizophrenia in our treatment of violence among the young. Parents do not encourage violence, but neither do they take up arms against the industries which encourage it. Parents hide their eyes from the books and comics, slasher films, videos and lyrics which form the texture of an adolescent culture. While all successful societies have inhibited instinct, ours encourages it. Or at least we profess ourselves powerless to interfere with it.
    C. John Sommerville (20th century)
