M150 Electret Microphone
The M150 is a high performance microphone
with heavily suppressed mechanical noise for
critical applications. A wide, flat frequency
response is augmented by a 2 or 3 dB bump in
the upper octaves to add a crisper sound. The
mic capsule should be positioned in the center of
the talker’s chest, not to either side, as high up
as is practical. In windy conditions, it can be
placed underneath a collar or thin clothing to
reduce wind noise, although this will dull the
sound somewhat.
