Description The "Open Cardioid" pickup pattern was introduced by SCHOEPS in 2008. It lies between the classic cardioid and the wide cardioid, achieving both a fair amount of directivity and very natural sound quality. Many years' experience of professional recording engineers with the range of Schoeps cardioids has played a large role in the development process. Meanwhile the MK 22 has become a preferred soloist and spot microphone, thus becoming an alternative to the "classic" MK 4.
