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:
“A true proposition is a proposition belief which would never lead to such disappointment so long as the proposition is not understood otherwise than it was intended.”
—Charles Sanders Peirce (1839–1914)
“When one has come to accept a certain course as duty he has a pleasant sense of relief and of lifted responsibility, even if the course involves pain and renunciation. It is like obedience to some external authority; any clear way, though it lead to death, is mentally preferable to the tangle of uncertainty.”
—Charles Horton Cooley (1864–1929)
“The wolf also shall dwell with the lamb, and the leopard shall lie down with the kid; and the calf and the young lion and a little child shall lead them.”
