The Sennheiser E904 is a cardioid instrument microphone primarily designed to reproduce drums and percussion instruments with incredible richness and detail. The E904 features a dynamic element with a cardioid polar pattern that reduces off-axis signal and residual noise. The E904 provides high headroom and low distortion when capturing signals at excessive sound pressure levels. The element responds to very fast attacks with extreme accuracy, without distortion. The E904 is an excellent choice for capturing snare drums, toms, congas, and more.
