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.
