AT4022

Audio-Technica AT4022 – Small-diaphragm omnidirectional microphone for acoustic instruments

The Audio-Technica AT4022 is a small-capsule microphone designed to capture acoustic instruments such as piano, guitar and percussion with precision and natural detail. Its omnidirectional polar pattern preserves the ambience and tonal character of the recording environment, delivering a faithful and well-balanced reproduction.

With its flat and extended frequency response, wide dynamic range and ability to handle up to 156 dB SPL (with attenuator), the AT4022 excels both in studio and live settings, even in the most demanding situations.

Its low-mass capsule ensures an excellent transient response while minimizing mechanical noise transfer. The microphone also features a switchable 80 Hz low-cut filter and -10 dB pad, further enhancing its versatility for powerful and percussive sources.

Thanks to its very low self-noise and Japan-made construction, it delivers outstanding reliability and consistent sonic performance. Supplied with the AT8405a shock-mount clip, a windscreen and a semi-rigid protective case, it integrates seamlessly into any professional setup.
