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:
“Methods of thought which claim to give the lead to our world in the name of revolution have become, in reality, ideologies of consent and not of rebellion.”
—Albert Camus (1913–1960)
“We have been educated to such a fine—or dull—point that we are incapable of enjoying something new, something different, until we are first told what it’s all about. We don’t trust our five senses; we rely on our critics and educators, all of whom are failures in the realm of creation. In short, the blind lead the blind. It’s the democratic way.”
—Henry Miller (1891–1980)
“The whole theory of modern education is radically unsound. Fortunately in England, at any rate, education produces no effect whatsoever. If it did, it would prove a serious danger to the upper classes, and probably lead to acts of violence in Grosvenor Square.”
—Oscar Wilde (1854–1900)
