Concealing a lavalier microphone — In some productions, it is neces-
sary to conceal the microphone. It is important to prevent both the micro-
phone and the first few inches of cable from rubbing against either the body
or clothing, which will cause noise. Here are some options:
•
Under the shirt collar. The mic is lightly taped to the inside of a dress
shirt collar, near the opening in front. The cable can be routed around
to the back of the neck, over the collar and under the shirt.
•
On eyeglasses, on the inside of the temple. The cable is routed over
the ear and down the back.
•
On the forehead or cheek, secured with medical tape or gum.
A disadvantage of this method is that the microphone is directly
exposed to perspiration and makeup.
•
On the chest, secured with double-sided tape to both the skin and the
inside of the shirt. Try to avoid placing the mic behind any material
having more than one layer. This reduces pickup of high frequencies,
which results in a flat, “muddy” sound.
Double-miking — In some cases, even a remote chance that the
microphone might fail during a live event constitutes an intolerable risk. For
this reason, a news anchor or key presenter may wear two lavalier
microphones for redundancy.
Only one mic is used at a time;
if the primary mic fails, the
backup mic channel can be
turned up immediately.
A lavalier microphone should be positioned six to eight
inches below the wearer’s chin (Shure WL93 shown).
