PRACTICE

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. Therefore, the Decca-Tree set is equipped with compact CCM microphones or with a CMC 1 L amplifier and capsule. 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.
