CCM 4

Compact Microphone

Features

  • classic cardioid
  • suitable for the widest range of applications, either as a spot microphone or for stereo recording with coincident, ORTF or M/S microphone arrangements
  • consistent directionality throughout its frequency range
  • often preferred for singing or speaking voices and most instruments

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 4)
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. 121015 CCM 4 L (standard Lemo version)
  • No. 121016 CCM 4 K (fixed cable version with XLR)

Description

The CCM 4 is our best-selling compact microphone. It offers the highest sound quality, flat frequency response, optimal rejection of rear-incident sound, and a directional pattern that remains constant throughout the audio frequency range. In the diffuse sound field it shows only a mild rise around 10 kHz. The sonic impression is thus free of coloration whether sound is arriving at the front or at the sides of the microphone, as well as for diffuse sound (reverberation) in a room.

The CCM 4 is our best-selling compact microphone. It offers the highest sound quality, flat frequency response, optimal rejection of rear-incident sound, and a directional pattern that remains constant throughout the audio frequency range. In the diffuse sound field it shows only a mild rise around 10 kHz. The sonic impression is thus free of coloration whether sound is arriving at the front or at the sides of the microphone, as well as for diffuse sound (reverberation) in a room.

By design, the CCM 4 was optimised for rejection of rear-incident sound. As is typical of a classic cardioid, the attenuation at 90° incidence angle is 6 dB and at 180° it reaches 20-30 dB. Diffuse sound is reduced by 4.8 dB compared to frontally-incident sound - a value corresponding to the directivity index. The higher this value is, the less room sound the microphone picks up, thus lowering the risk of acoustic feedback.

Thanks to its directivity, the CCM 4 can achieve the same diffuse-to-direct sound balance from 1.7 times the distance to the sound source compared to a pure pressure transducer with the same sensitivity.

Practice

The CCM 4 is suitable for recording both speech and music. It is used equally often as a spot or studio microphone or as part of a stereo array. For example, the ORTF-Stereo technique with STC is realised using this microphone. Excellent results can be achieved with a CCM 4 as the mid microphone in a M/S arrangement or with two CCM 4 as a XY stereo pair.

This microphone type is exceptionally universal and thus most often used.

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.
