• omnidirectional pattern
• diffuse-field capsule
• for miking distances at which the predominant sound is no longer direct
• useful for relatively distant placement in reverberant environments – as a room microphone, for “spaced microphone” stereo pickup and in “Decca Tree” arrangements

Compact Microphone CCM 3

The CCM 3 is designed for placement in a diffuse sound field, i.e. at distances in reverberant environments where the greater portion of arriving sound has already been reflected from various room surfaces. In such placement the integrated frequency response of this capsule is essentially flat; the on-axis high-frequency response elevation shown in the graph below is not heard as such. It is remarkable how well-focused a recording can be made with omnidirectional microphones at such distances, when the microphones have been designed and placed appropriately.

But when sound arrives from nearby sources in front of the capsule, high frequencies are distinctly accented, leading to a sound image with special brilliance.
