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.
