Microphone Placement
---
Aim the microphone toward the desired source, such as the
talker.
Aim it away from any unwanted source, such
as
a loudspeaker.
Place
the microphone within 15 to
30cm
(6 to 12 in.) of the desired sound source.
Always
use the supplied
windscreen or
optional metal windscreen to
control
breath noise.
If
four or more microphones
will be open at the same time,
use of an automatic
mixer, such as the Shure SCM810
or SCM410,
is recommended.
