Cardioid Lavalier Mic with Preamp & Accessories. The Shure MX185 is a wired Lavalier electret condenser microphone designed for speech and vocal pickup, general purpose sound reinforcement, recording, and remote monitoring applications. It can be clipped to neckties, lapels, and other articles of clothing. The MX185 Lavalier microphone features a cardioid microphone cartridge and provides good rejection of ambient noise. Includes belt-clip preamp, rotatable tie clip, dual tie clip, and snap-fit windscreen. Features: Flat frequency response across the vocal range for uncolored sound Interchangeable cardioid, supercardioid, and omnidirectional cartridges that provide optimal choice for each application Sleek, low-profile design for unobtrusive appearance Balanced, transformerless output for increased immunity to noise over long cable runs Advanced RF filtering Specifications: Type: Condenser (electret bias) Frequency Response: 50 to 17,000 Hz Polar Pattern: Cardioid Pickup angle: 130 degrees Output Impedance: EIA rated at 150 ohms (180 ohms actual) Open Circuit Sensitivity (at 1 kHz, ref. 1V/Pascal*):-35.0 dB (17.0 mV) All settings -12 dB at 0 gain *1 Pascal = 94 dB SPL Max SPL: (1kHz at 1%THD, 1 k ohm load): 124.2 dB All settings +6 dB at 0 gain Equivalent Output Noise (A-weighted): 28.0 dB Signal to Noise Ratio (referenced at 94 dB SPL): 66.0 dB Dynamic Range at 1 k ohm load: 96.2 dB, 100 dB at 0 gain Power Requirements: 11 to 52 Vdc phantom, 2.0 mA Common Mode Rejection: 45.0 dB minimum Polarity: Positive sound pressure on diaphragm produces positive voltage on pin 2 relative to pin 3 of output XLR connector Environmental Conditions: Operating Temperature Range: -18 to 57 degrees C (0 to 135 degrees F); Storage Temperature Range: -29 to 74 degrees C (-20 to 165 degrees F) Cable: Shielded 1.2 meter (4 ft.) cable terminated with a 4-Pin Female Mini Connector (TA4F) Dimensions (length x diameter): 3.89 " x .79" (99 x 20 mm)
