Audio-Technica AT2031 - Cardioid Condenser End Address Microphone

The Audio-Technica AT2031 is a cardioid condenser end-address microphone designed for critical studio and live applications, particularly excelling in capturing the nuances of stringed instruments such as violins, cellos, acoustic guitars, harps, and pianos.

Key Features:

• Permanently Polarized Condenser Element: The AT2031 utilizes a permanently polarized condenser element, offering an extended frequency response with a slight rise in the high-frequency range. This design enhances the detail and clarity of the captured sound, making it ideal for intricate acoustic performances.

  
  

• Cardioid Polar Pattern: Its cardioid polar pattern improves isolation of the desired sound source by reducing the pickup of sounds from the sides and rear. This feature is particularly beneficial in live settings or untreated rooms, where ambient noise can be a concern.

  
  

• Low Self-Noise and High SPL Handling: The microphone boasts a low self-noise level, making it well-suited for digital recording equipment. Additionally, it can handle high sound pressure levels (up to 141 dB SPL), offering a wide dynamic range that accommodates both delicate and powerful sound sources without distortion.

  
  

• Switchable High-Pass Filter: A switchable 150 Hz 6 dB/octave high-pass filter is included to reduce low-frequency noise and rumble, ensuring cleaner recordings.
