Overview

The AT4022 is a low-profile omnidirectional condenser microphone designed for high-performance recording in both studio and live settings. Its omnidirectional polar pattern captures sound uniformly from all directions, providing maximum ambient pickup and freedom from proximity effect. This microphone is equipped with a low-mass diaphragm that enhances transient response and reduces mechanical noise transfer, making it ideal for recording a wide range of acoustic instruments. With features like a switchable 80 Hz hi-pass filter and a 10 dB pad, the AT4022 is a versatile and reliable choice for professional audio applications.
