Dual-Pattern Instrument Microphone

End-address condenser microphone with mechanically switching dual polar patterns.

 

Dual pattern instrument microphone offers transition between cardioid and omnidirectional patterns and features extended frequency response, pad for handling SPLs, a gold-layered Mylar diaphragm, and a subsonic filter for low frequency rumble.

 

  • A mechanical polar pattern switch for highly consistent cardioid and true omnidirectional polar patterns. Provides flexibility in a wide variety of recording applications
  • Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar® diaphragm for superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
  • Premium electronic components, including gold-plated internal and external connectors
  • Subsonic filter eliminates low frequency rumble (less than 17 Hz) caused by mechanical vibration
  • Three-position switchable pad (0 dB, 15 dB, and 25 dB) for handling extremely high sound pressure levels (SPLs)
  • Three-position switchable low-frequency filter to reduce background noise and counteract proximity effect

Performance Characteristics

  • Extended frequency response
  • Low self-noise
  • Exceptional reproduction of low-frequency sounds
  • Can withstand high sound pressure levels (SPL)
  • High output level
  • No crossover distortion
  • Uniform polar response
  • Superior common mode rejection and suppression of radio frequency interference
