Audio-Technica AT4021

Ideal for critical studio and live applications, the low-profile AT4021 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. +2 Features Outstanding performance and rugged construction High SPL handling and wide dynamic range Flat, extended frequency response Switchable 80 Hz hi-pass filter and 10 dB pad High front-to-back rejection ratio—cardioid polar pattern improves isolation of desired sound source Low self noise perfectly suited for digital recording equipment Exceptional reproduction of low frequency sounds Low-mass element for superb transient response Specifications
