CMC 6xt

Mikrofonverstärker HiRes


  • The CMC 6xt is the HiRes version of the CMC 6.
  • Using this amplifier, the frequency range of all axially-addressed capsules (MK 2 H/S, 21, 22, 4, 41, 5) can be extended up to 40 kHz
  • Especially useful when recording with a high sample rate, particularly with the intent to slow down the recording and reduce its pitch by one or more octaves at a later point (e.g. for sound design)

Order number

  • No. 132007


The CMC 6xt extends the frequency response of the MK capsules up to 40 kHz.

Attention was paid to a low self-noise above 20 kHz. This maintains a high level of dynamics when recording at high sampling rates. Thus, the often very small signal above 20kHz is not covered and the noise is still low even after the down pitching.
