The Decca Tree Set "2H / 2S" consists of the following items:

  • 3 * No. 121009: Compact Microphone CCM 2H (2S: No. 121011)
  • 2 * No. 191701: Matching incl. certificate
  • 3 * No. 169001: KA 40, sphere attachment
  • all in one wooden box

The Decca Tree Set "2S" contains three CCM 2S instead of the CCM 2H.


The Decca Tree is a triangular arrangement of three omnidirectional microphones. The microphones should be placed at least 1.5 m apart to reduce crosstalk and excessive correlation at low frequencies.

Often the microphones of a Decca Tree must be suspended from above. This is why the Decca Tree set uses our compact CCM series microphones. The KA 40 accessory mounting spheres cause increased directivity between 1 and 4 kHz, which in turn increases the differences among the signals picked up by each microphone. The M 50 microphones used in the original Decca Tree (1950s) were built on this same principle.
