The Lectrosonics M152 Omnidirectional Lavalier Microphone is a highly sensitive, and features a wide frequency response that accentuates the presence and character of the human voice. The M150's frequency response is measured at 20Hz to 20kHz with a slight rise around 10kHz, resulting in a brighter, more airy response. A low frequency dip around 50Hz reduces noise caused by proximity effect and ambiance.
