The Microtech Gefell M 900 cardioid condenser microphone has been developed for recordings of instrumental and vocal soloists in the professional market. Its well balanced frequency response in the free-field as well as in the diffuse-field and the appropriate distinct characteristics ensure clean and colourless recordings of any sound sources with good selectivity.

A distance of less than 8 to 12 inches, which is recommended as minimum distance between lips and microphone, causes a coloration with an emphasis of lower frequencies, the proximity effect.

An acoustic filter integrated in the protective basket reduces the pop sensitivity. The direction of maximum sensitivity is axial, i.e. endwise to the microphone. This fact and the ergonomic design make these microphone the right choice for live performance of soloists.
