specification
The M 900 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 colorless recordings of any sound sources with good selectivity. A distance of less than 8 to 12 inches, which is recommended as the minimum distance between lips and microphone, causes a coloration with an emphasis on lower frequencies, the proximity effect. An acoustic filter integrated into the protective basket reduces pop sensitivity.
