Audio-Technica AT4021 Small-Diaphragm Cardioid Condenser Microphone

The low-profile AT4021 is the mic you'll want when it comes to your critical studio and live audio capture applications. That's because it offers a flat, extended frequency response, high maximum sound pressure level (SPL)-handling capabilities, a wide dynamic range and outstanding reproduction of low-frequency sounds. It features low self-noise, making it extremely suitable for even the most sophisticated recording equipment. It comes equipped with a low-mass diaphragm for enhanced transient response and bandwidth. It also provides reduced handling and mechanical noise transfer as well.
