The Audio Technica AT4051A-EL is the cardioid, condenser capsule for the AT4051 microphone. The AT4051A-EL handles sound pressure levels (SPL) up to 143dB at no greater than 1% THD, a suitable solution for percussion and drums as well as brass and other sources high in volume. The microphone features a frequency response of 20Hz to 20kHz an the cardioid polar pattern eliminates off-axis noise and feedback.
