- Set with three CCM microphones for Stereo Recording with a "Decca Tree"
- includes sphere attachments
- No. 129002 Decca Tree Set 2H
- No. 129001 Decca Tree Set 2S
The Decca Tree Set "2H / 2S" consists of the following items:
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.
