904 High-quality dynamic microphone with cardioid pick-up pattern. Due to its compact design, the microphone is ideal for use with drums (toms and snares). It can easily be positioned in cramped space conditions (e.g. below the cymbals) and the supplied MZH 604 microphone clamp allows to precisely attach it to the rim of the instrument. The 904 is also suitable for miking guitar amplifiers, percussions as well as brass and woodwind instruments.
