  • Schoeps CMC 1 U Preamp Body in stock! We ship fast!

  • No cable supplied with this version of the CMC1.  Conventional XLR output.
  • Complete compact alternative to the renowned CMC 6
  • Fully compatible with all existing MK capsules and Colette active accessories such as the CUT 60 and RC tubes
  • Suitable mounting accessories are already available, such as the CINELA E-OSIX-CMC1U and the Rycote INV-6 elastic suspensions.

The CMC 1 U is our new, small Colette microphone amplifier, about one-third the length and 53% lighter than the CMC 6. It is compatible with all components of the Colette system and can be used in place of the CMC 6 without compromise, for all applications in which the size and weight of the microphone play a role.

At SCHOEPS, “uncompromising miniaturization” means that the electrical characteristics of the CMC 1 are equal to, or even better than, those of the CMC 6. Through modern electronic design, these outstanding electrical properties have been achieved:

  • high maximum SPL: 135 dB-SPL with the MK 4 (0.5% THD or less)
  • very low current consumption: 2.0 mA at 48 Volts
  • operates on 48 V or 12 V phantom power, reliable operation even if powering is somewhat marginal
  • very high immunity from RF interference with the SCHOEPS RFI Shield; high immunity to cable-induced hum and other interference (field tested with Audio Limited A 10, etc.)
  • flat frequency response
  • very low distortion constant output impedance across the audio frequency range
  • balanced, direct-coupled, class-A output circuit
  • output is filtered in the ultrasonic range to prevent interference, e.g. from camera autofocus
  • Includes mic clip for easy attachment to a mic stand

A complete Colette-series microphone consists of an MK capsule and a CMC amplifer. All capsules and active accessories of the Colette system are compatible with the CMC 1.

The CMC 1 U operates with standard 12-Volt or 48-Volt phantom powering. Power consumption is lower at 12 Volts--an advantage for battery-powered operation
