Shure SM93 Miniature Lavalier Condenser Microphone


Subminiature lavalier design; ideal size for theater, television broadcasting,
video, film, and sound reinforcement
Small, inconspicuous mounting hardware
Full, clear sound comparable to larger microphones
Smooth extended frequency response with presence rise specially
tailored for chest-worn microphone operation
Controlled low-frequency rolloff reduces low-frequency clothing and room noise
Low distortion, wide dynamic range
Versatile mounting accessories allow a variety of low-visibility applications
Preamplifier assembly can be pocketed, strapped to the body,
or clipped to belt or waistband
Wide-range phantom powering accepts all commonly used voltages


Type: Condenser (electret bias)
Frequency Response: 80-20,000 Hz, 12 dB/octave roll-off below 100 Hz
Polar Pattern: Omnidirectional, uniform with frequency
Output Impedance: Rated at 150 ohms (90 ohms actual)
Recommended minimum load impedance: 800 ohms (May be
used with loads as low as 150 ohms with reduced clipping level)
Output Level, Open Circuit Voltage: -43 dBV/Pa (7.0 mV)
Output Clipping Level (at 1,000 Hz): -18 dBV (0.13 V) minimum
Total Harmonic Distortion: Less than 1% at 120 dB
Maximum SPL: 120 dB
Dynamic Range (maximum SPL to A-weighted noise level): 98 dB
Output Noise (equivalent SPL): 22 dB typical, A-weighted; 26 dB,
weighted per DIN 45 405
Hum Pickup (electromagnetic): -4 dB equivalent SPL in a 1 mOe field (60 Hz)
Signal-to-Noise Ratio: 72 dB at 94 dB SPL (IEC 651)
Polarity: Positive pressure on microphone diaphragm produces
positive voltage on pin 2 relative to pin 3 of preamplifier output cable connector
Recommended Operating Voltage: 11 to 52 Vdc Phantom.
Protected against reverse voltage application
Current Drain: 0.33 mA
Environmental Conditions: Operating Temperatures: –18 to 57
degrees C (0 to 135 degrees F), Storage Temperatures:
–29 to 74 degrees C (–20 to 165 degrees F)
Cable: Black 1.27m (4.17 ft), attached, two-conductor, shielded,
 terminated by miniature connector type (TA4F)
Case: Microphone: Black ABS thermoplastic case with
stainless-steel-mesh grille, Preamplifier: Steel case with
non-reflective black finish, black-chrome belt clip
