What is a Lavalier Microphone
(More)?
A lavalier microphone or lavalier (or lav or lapel mike) is
a small electret or dynamic microphone used for television,
theatre, and public speaking applications, in order to allow
hands-free operation. They are most commonly provided with
small clips for attaching to collars, ties, or other
clothing. The cord may be hidden by clothes and either run
to a radio frequency transmitter in a pocket or clipped to a
belt (for mobile work), or directly to the mixer (for
stationary applications).
These miniature mics are often supplied with a choice of
push-on grilles of differing lengths which provide gentle
high-frequency boost by forming a resonant cavity. A peak of
around 6 dB at 6-8 kHz is considered beneficial for
compensating loss of clarity when chest mounted, and a peak
of a few decibels at 10-15 kHz when mounted in the hair
above the forehead. This method of boosting high frequencies
does not worsen noise performance, as electronic
equalization would do. |
