What is Line level?
'''Line level''' is the strength of an audio signal. An audio signal transfers sound, for example to CD players and cassette players. It is much higher than microphone level, which can be only a couple of milli[[volt]]s. A line level signal can be connected to an [[amplifier]] which sends the signal to [[loudspeaker]]s with much higher [[Electric power|power]]. A [[preamplifier]] is a device that can make the line level higher. It can boost a [[microphone]]'s weak audio signal. {{tech-stub}} [[category:Audio technology]]
