Cardioid Pencil Condenser Microphone

The AT3031, a low-profile cardioid condenser microphone from Audio-Technica’s renowned 30 Series, is known for a flat, extended frequency response, high maximum SPL and wide dynamic range. Its low self-noise (16 dB SPL) is perfectly suited for the most sophisticated recording equipment. Its low-mass diaphragm improves transient response, increases response bandwidth and reduces handling and mechanical noise transfer.

  • High max SPL and wide dynamic range
  • Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source
  • Low self-noise (16 dB SPL) — perfectly suited for today’s most sophisticated digital recording equipment
  • Flat, extended frequency response
  • Lo-cut switch (80 Hz, 12 dB/octave) and 10 dB pad

See also the AT3032, which is the same mic with an omni pickup pattern.

These mics are reported to have been manufactured in Japan, and may have inspired the Chinese pencil condensers, which look much the same. See, for example, the Feilo CR1-14 and its clones.
