The AT4021 Cardioid Condenser Microphone from Audio-Technica features a low-profile design and small-diaphragm condenser element. The microphone’s sensitivity, frequency response, and SPL capabilities are suitable for use with speaker cabinets, vocals, percussion instruments, drums, and spot placement on guitars, and stringed instruments. There is a cardioid polar pattern for minimizing noise and off-axis feedback and an 80 Hz high-pass filter switch for reducing low frequencies and associated noise. Additionally, a -10 dB Pad switch provides extra headroom and minimizes distortion when capturing transient (peaking) audio signals. The package includes a stand clamp, a windscreen, and a protective carrying case.

Cardioid Polar Pattern

The cardioid polar pattern minimizes noise and off-axis feedback.

Switchable 80 Hz High Pass Filter

The 80 Hz high-pass filter switch reduces hum, low frequency noise, and rumble.

-10 dB Pad Switch

A -10 dB Pad provides additional headroom for capturing peaking audio signals without distortion and noise.
