The Lectrosonics M152 is a highly sensitive Omnidirectional Lavalier Microphone featuring a wide frequency response that accentuates the presence and character of the human voice. The sleeve is moisture resistant and compliments the water-tight characteristics of the SM series transmitters.
The M152'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. The omnidirectional polar pattern provides a generous response at the direct and off-axis sections of the microphone capsule.
