SCHOEPS Decca Tree Set

Product overview

The SCHOEPS Decca Tree Set is a complete set for stereo recording with a Decca Tree: three omnidirectional microphones, sphere attachments and miniature cable hangers.

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. Because the microphones of a Decca Tree often have to be suspended from above, the set is equipped with compact CCM microphones, or with CMC 1 L amplifiers and MK capsules in the modular version.

The KA 40 sphere attachments increase the directivity between 1 and 4 kHz, which in turn increases the differences among the signals picked up by each microphone. The original Decca Tree microphones of the 1950s were built on this same principle. Two of the three microphones are matched, with a certificate.

SCHOEPS Decca Tree Set: frequently asked questions

What is a Decca Tree?

A triangular arrangement of three omnidirectional microphones, left, centre and right, for stereo recording. The microphones should be at least 1.5 m apart.

What do the KA 40 spheres do?

They increase the directivity between 1 and 4 kHz, which increases the differences among the signals of the three microphones.

Which versions are available?

With three CCM 2S or three CCM 2H compact microphones, or in modular form with CMC 1 L or CMC 1 U amplifiers and MK 2S or MK 2H capsules.

Why compact microphones?

The microphones of a Decca Tree often have to be suspended from above, so the set uses compact CCM microphones or CMC 1 L amplifiers, hung with the included HC 3 miniature cable hangers.

Where can I buy the SCHOEPS Decca Tree Set in India?

The SCHOEPS Decca Tree Set is available from Shivansh Electronics, Kolkata, West Bengal, India, with delivery across India.

Workflow 1: Suspended Decca Tree over an orchestra

Classical recording engineers in concert halls.

Connections

Setup

1. Fit a KA 40 sphere to each microphone.
2. Hang left, centre and right microphones with the HC 3 hangers in a triangle.
3. Keep the microphones at least 1.5 m apart.
4. Route L, C and R to three channels and balance them in the mix.

Tip: Greater spacing reduces crosstalk and excessive correlation at low frequencies.

Workflow 2: Modular Decca Tree

Users who prefer the Colette modular system.

Connections

Setup

1. Order the set in modular form with CMC 1 amplifiers and MK capsules.
2. Screw the capsules onto the amplifiers and fit the spheres.
3. Arrange the three microphones as a triangle and record three channels.

Tip: The CMC 1 L version suits suspension from above.
