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:
“There is a lot of difference between tempting and leading into error. God tempts but does not lead into error. To tempt is to provide opportunities for us to do certain things if we do not love God, but putting us under no necessity to do so. To lead into error is to compel a man necessarily to conclude and follow a falsehood.”
—Blaise Pascal (1623–1662)
“I love all men who dive. Any fish can swim near the surface, but it takes a great whale to go down stairs five miles or more; & if he don’t attain the bottom, why, all the lead in Galena can’t fashion the plummet that will.”
—Herman Melville (1819–1891)
“Wine does not intoxicate people—they do it themselves; beauty does not lead men astray—they lead themselves astray.”
—Chinese proverb.
