The M152 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.
The "SM5P" designation indicates it has the standard Lectrosonics 5-pin TA5F connector and is intended to work with most modern Lectrosonics bodypack transmitters that use the 5-pin input.
Compatible transmitters include:
SMV series transmitters
SMQV series transmitters
SMDB series transmitters
SMWB series transmitters (same TA5 wiring standard)
LMa beltpack transmitters
LMb beltpack transmitters
LT plug-on/bodypack transmitters that accept the Lectrosonics 5-pin input standard
UM400a and other Digital Hybrid transmitters using the Lectrosonics TA5 audio connector
