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.
