The Sennheiser e 604 Microphone is a rugged, cardioid instrument microphone that is specially designed to handle the high sound pressure levels of drums, percussion, and brass instruments without noise and peak distortion.
The e 604 features a cardioid polar pattern that is effective in minimizing noise and feedback at the off-axis sections of the capsule. The element features a neodymium magnet with boron, which yields a high output gain with low noise and reliable performance, regardless of climate. An integral stand mount screws directly onto mic stands and the included clip attaches the microphone to the rim of a drum.
