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:
“I have no scheme about it,—no designs on men at all; and, if I had, my mode would be to tempt them with the fruit, and not with the manure. To what end do I lead a simple life at all, pray? That I may teach others to simplify their lives?—and so all our lives be simplified merely, like an algebraic formula? Or not, rather, that I may make use of the ground I have cleared, to live more worthily and profitably?”
—Henry David Thoreau (1817–1862)
“My Vanquisher, spoild of his vanted spoile;
Death his deaths wound shall then receive, & stoop
*nglorious, of his mortall sting disarm’d.
I through the ample Air in Triumph high
Shall lead Hell Captive maugre Hell, and show
The powers of darkness bound. Thou at the sight
Pleas’d, out of Heaven shalt look down and smile,”
—John Milton (1608–1674)
“Many will come in my name and say, I am he!’ and they will lead many astray.”
—Bible: New Testament, Mark 13:6.
