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:
““Yet let him keep the rest,
But keep them with repining restlessness:
Let him be rich and weary, that at least,
If goodness lead him not, yet weariness
May toss him to My breast.””
—George Herbert (1593–1633)
“Persons who insist to themselves that under one set of conditions only can they lead interesting and satisfying lives lay themselves open to bitter disappointments and frustrations.”
—Hortense Odlum (1892–?)
“Many of us, whether in the jungles of Asia or on the streets of Chicago, had discovered that noble causes can lead to ignoble actions and that we were capable of sacrificing honor to a sense of efficacy.”
