AT4021 - Overview

Ideal for critical studio and live applications, the Audio-Technica AT4021's low-profile offers a flat, extended frequency response, high maximum SPL and wide dynamic range. Its low self-noise is perfectly suited for the most sophisticated recording equipment. Its low-mass diaphragm improves transient response, increases response bandwidth and reduces handling and mechanical noise transfer. The microphone offers outstanding reproduction of low-frequency sounds.The AT4021 is intended for use in professional applications where remote power is available. It requires 48V DC phantom power, which may be provided by a mixer or console, or by a separate, in-line source such as the Audio-Technica AT8801 single-channel or CP8506 four-channel phantom power supplies.
