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.
NOTE: M150 lavalier microphone with TA5F 5-pin connector for Lectrosonics belt-pack transmitters is specified with model number M150-5P.
