M119 Electret Microphone The M119 microphone exhibits a broad, flat frequency response well suited to tape recording or speech reinforcement applications. The omnidirectional pickup pattern makes the exact placement of the mic less critical than directional types. 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. Typical Frequency Response Curve Relative Response dB +20 +10 0 -10 -20 -30 20 50 100 200 1k 500 Frequency Hz 2k 5k 10k 20k Sensitivity: -66dB ±3dB (0dB=1V/uBAR@1kHz) Impedance: Low impedance Polar Pattern: Omnidirectional Freq Range: See below Max Operating Voltage: 10V Standard Operating Voltage: 2.0V Current Consumption: 0.5 mA max Signal/Noise Ratio: More than 38dB 581 Laser Road, Rio Rancho, NM 87124 USA phone (800) 821-1121 or (505) 892-4501 fax (505) 892-6343 e-mail: [email protected]
