About Audio-Technica AT4021

The Audio-Technica AT4021 Cardioid Condenser Microphone features a low-profile design and small-diaphragm condenser element. The sensitivity, frequency response and SPL capabilities make it a suitable choice for speaker cabinets, vocals, percussion instruments, drums and "spot" placement on guitars, stringed instruments, etc.

The cardioid polar pattern effectively minimizes noise and off-axis feedback. An 80Hz high-pass filter switch reduces low frequencies and all associated noise. In addition a -10dB Pad switch provides added headroom and minimizes distortion when capturing transient (peaking) audio signals.

Audio-Technica AT4021 Features

  • Outstanding performance and rugged construction
  • High SPL handling and wide dynamic range
  • Flat, extended frequency response
  • Switchable 80 Hz hi-pass filter and 10 dB pad
  • High front-to-back rejection ratio-cardioid polar pattern improves isolation of desired sound source
  • Low self noise perfectly suited for digital recording equipment
  • Exceptional reproduction of low frequency sounds
  • Low-mass element for superb transient response
