Schoeps Decca Tree Set 2 S

The Decca Tree Set consists of:

• three microphones for Stereo Recording with a "Decca Tree"
• sphere attachments
• miniature cable hangers

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

• 3 * No. 121009: Compact Microphone CCM 2H
• 2 * No. 191701: Matching incl. certificate
• 3 * No. 169001: KA 40, sphere attachment
• 3 * No. 161806: HC 3, Miniature cable hangers

The Decca Tree Set CCM 2S contains three CCM 2S (No. 121011) instead of the CCM 2H.

The Decca Tree Set CMC 1L + MK 2S contains three CMC 1 L (No. 132012) and three MK 2S (No. 131011) in place of the CCM 2H.

The Decca Tree Set CMC 1L + MK 2H contains three CMC 1 L (No. 132012) and three MK 2H (No. 131009) in place of the CCM 2H.

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.
