Audio-Technica AT4021 End-address cardioid condenser microphone
Product Overview
The Audio-Technica AT4021 is an end-address cardioid condenser microphone in a compact pencil form, built for detailed capture of acoustic instruments, overheads, and ensembles. Its cardioid pattern and fast transient response make it a precise cardioid condenser microphone for broadcast studios, auditoriums, and houses of worship. A switchable 10 dB pad extends its high-SPL capability.
Product Description
The AT4021 delivers accurate, transparent reproduction with a focused cardioid pattern that rejects off-axis sound, which suits acoustic guitar, piano, strings, and drum overheads. The pencil body mounts easily on stands and overhead arrays.
Frequency response runs 20–20,000 Hz with a 19.9 mV output sensitivity, and a switchable 10 dB pad raises the maximum SPL capability to 156 dB for loud sources. The microphone requires 48V phantom power.
For an omnidirectional pencil in the same family, see the AT4022; for a matched stereo pair, the AT4041SP studio pack is a complete option.
