Lead
Since a VU meter does not reflect the signal peaks for complex wave forms and for varying program material, it might be easy to overload a recording device or broadcast system. To protect against this, a lead or margin of safety may be inserted in the meter circuit. This consists, in effect, in an amplifier making the VU meter commonly 6 or 8 dB more sensitive.

Famous quotes containing the word lead:
“Those who follow where their genitals lead them often wind up in tedious company.”
—Mason Cooley (b. 1927)
“I also believe that few people remain completely untouched by the thought that instead of the life they lead there might also be another, where all actions proceed from a very personal state of excitement. Where actions have meanings, not just causes. And where a person, to use a trivial word, is happy, and not just nervously tormenting himself.”
—Robert Musil (1880–1942)
“I know what Germans are. They are a funny people. They are always choosing someone to lead them in a direction which they do not want to go.”
—Gertrude Stein (1874–1946)
