Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Line level is a term used to denote the 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, and sometimes MP3 players. In contrast 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 the various signals does not necessarily correlate with the output voltage of a device; it also depends on the source”s output impedance, or the amount of current available to drive different loads. Consumer electronic devices concerned with audio often have a connector labeled line in” and/or “line out”. Line out provides an audio signal and line in receives one. The connection is typically unbalanced using a TRS connector of 6.35 mm, 3.5 mm or 2.5 mm. For example, when recording from the ”line” output of a radio receiver, varying the speaker volume does not vary the strength of the ”line out” signal. ”
