CCM 2XS

Compact Microphone

Features

  • omnidirectional pattern
  • diffuse-field equalised 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 stereophony and in Decca Tree arrangements

This microphone can also be ordered as a modular Colette microphone, where the CMC 1 L amplifier is combined with an MK microphone capsule. (CMC 1 L + MK 2XS)
This variant allows the capsule to be exchanged and has advantages in terms of electrical properties in combination with digital wireless transmitters.


Order number

  • No. 121013 CCM 2XS L (standard Lemo version)
  • No. 121014 CCM 2XS K (fixed cable version with XLR)

Description

The CCM 2XS (formerly 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...

The CCM 2XS (formerly 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. If this type of microphone is used close to the sound source, the emphasis of high frequencies for on-axis sound incidence would become clearly audible, producing an overly brilliant sonic impression.

Since most recording today is miked more closely than in decades past, microphones such as the CCM 2S or CCM 2H are a reasonable norm for the majority of spaced-omni and “Decca Tree” applications. But if miking distances more typical of the mono and early stereo era are to be used, a capsule such as the CCM 2XS, with its full diffuse-field equalization, may well offer the optimal balance of focus, depth and spaciousness – and the KA 40 accessory spheres can then add a further measure of presence to the sound at such distances, if desired. The CCM 2XS is also often used as an ambient room microphone.

Product History

  • 1994: Launch of the CCM, hybrid technology circuit. The capsule part is identical to the MK capsules from the beginning  
  • 2016: better RF filter to protect from interferences
  • 2017: Polarization voltage generator now with higher frequency above 200 kHz due to downpitching in sound design applications.
