CCM 2H

Compact Microphone

Features

  • omnidirectional pattern
  • mild high-frequency rise to compensate for losses at medium recording distance
  • often chosen for spaced stereophony and 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 2 H)
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. 121009 CCM 2H L (standard Lemo version)
  • No. 121010 CCM 2H K (fixed cable version with XLR)

Description

If this microphone is used indoors at medium recording distances (i.e. where direct sound energy is similar in amount to reflected sound energy), its overall response will be linear. Its extended frequency response and low noise make it appropriate for the most demanding applications.

The sound inlet of the CCM 2H is narrower than that of our other pressure transducers, causing a slight, purely acoustic response elevation above 6 kHz. This reduces the high frequency loss for diffuse sound, thus helping to preserve natural sound quality.

Practice

The CCM 2H, like the CCM 2S, is ideal for natural-sounding pickup of instruments and orchestras in spaces with well balanced reverberance. The choice between the two capsule types is essentially a matter of personal preference. At a given miking distance the CCM 2H might be described as more ”balanced and round” sounding while the CCM 2S would give a slight additional brilliance. However, one might also choose the CCM 2H for slightly closer placement or the CCM 2S for slightly more distant placement – and then these two capsule types would have...

However, one might also choose the CCM 2H for slightly closer placement or the CCM 2S for slightly more distant placement – and then these two capsule types would have very similar sound quality, with the main difference then being in the balance of direct to reverberant sound which is picked up.

For spaced microphone (A/B) stereo recording and especially the Decca Tree method, KA 40 accessory spheres are recommended.

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.
