The SR30mp is a matched pair of directional pre-polarized condenser microphones with cardioid pickup pattern that are directly coupled to a dedicated wideband, low output impedance transformerless preamplifier. Mics feature a frequency response from 20Hz to 30kHz, fast impulse response, very low handling noise, uniform polar pattern, high SPL handling capabilities, and provide excellent uncolored rejection of sounds arriving off-axis.

Microphones are delivered with a calibration chart providing the individually measured frequency response curve. Mounting clips are included.


  • Extended frequency response to 30kHz
  • Multi-purpose cardioid microphone
  • More gain before feedback than other microphones
  • Less leakage
  • Textbook perfect cardioid polar pattern with natural on- and off-axis performance
  • Provides excellent results for both live performance and recording applications
  • Extreme accuracy in the time domain for faithful reproduction and no smearing or distortion
  • Transparent sound quality
  • Shorter diaphragm settling time to prevent quieter attacks from being blurred by earlier louder attacks
