Audio-Technica AT4021 UNIDIRECTIONAL CONDENSER MICROPHONE

Audio-Technica AT4021 Unidirectional Condenser Microphone

Description
The Audio-Technica AT4021 is a professional small-diaphragm, end-address condenser microphone designed for critical studio recording, broadcast, and live sound applications. Its cardioid (unidirectional) pickup pattern provides excellent isolation of the desired sound source while minimizing off-axis noise. With low self-noise, high SPL handling, and an extended frequency response, the AT4021 delivers detailed, natural audio reproduction for acoustic instruments, percussion, piano, overhead drum recording, stringed instruments, and other demanding recording situations.
