line level preampAn audio preamplifier that does not provide any compensation for phonograph or microphone input. Most preamps provide both line level and phono inputs. Extremely high-end audio preamps might eliminate a phono stage and require a separate device to equalize the LP signal (see phono preamp). See LP and preamplifier.
