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:
“But an old age serene and bright,
And lovely as a Lapland night,
Shall lead thee to thy grave.”
—William Wordsworth (1770–1850)
“For some years now, there has been proof that the devastating effects of the traumatization of children take their inevitable toll on society—a fact that we are still forbidden to recognize. This knowledge concerns every single one of us, and—if disseminated widely enough—should lead to fundamental changes in society; above all, to a halt in the blind escalation of violence.”
—Alice Miller (20th century)
“Learned researches lead to headaches, constipation, and befuddled quarreling.”
—Mason Cooley (b. 1927)
