Mono microphone kit including CMC 6U amplifier MK 5 Switchable capsule SG20 stand clamp B5 popscreen


  • flat frequency response
  • very low harmonic distortion and noise
  • works with 12V and 48V phantom power
  • balanced, low-impedance output
  • high suppression of interference on the microphone cable
  • excellent protection against high-frequency radio interference with "RFI Shield"
  • frequency-independent impedance
  • signal transmission possible over very long cables
  • reliable operation even with weak phantom power
  • symmetrical, transformer- and capacitor-free output stage with a class-A amplifier
  • above 20 kHz, the signal is attenuated for protection against interference in the ultrasonic range, e.g. through the ultrasonic autofocus of a film camera

The capsules of condenser microphones can't be connected directly to microphone cables or inputs; a microphone amplifier is required in between. Thus a complete microphone of the Colette series comprises any of the twenty available types of capsules combined with an amplifier. The CMC 6 U is designed for standard 48- and 12-Volt phantom powering. Its circuitry recognizes the supply voltage and adjusts itself automatically. Its performance characteristics remain essentially the same either way; mainly, the difference is that the current drawn at 12 Volts is greater than at 48 Volts. However, the 12-Volt mode consumes less power and might be preferred for battery-powered recording.

The microphone amplifier is responsible for providing the necessary electric charge to the capsule, without which it would be unable to generate a signal. Since the capsule's output signal is very weak (Hi-Z), it must be amplified. In order for the microphone's output to cleanly reach the next stage in the signal chain, it must undergo balancing and impedance matching before transmission. The CMC 6 incorporates a balanced, direct-coupled class-A amplifier, yielding a low output impedance, high RF shielding, and minimal distortion.


January 2019 New Gear Thread

two months ago i got a matched pair of mk4 cardioid capsules, and now i have finally completed the stereo setup with pair of cmc6 preamp bodies. mostly for recording nylon acoustic, violin, clarinet, basoon and possibly cello (haven't tried that in my space yet).

$5k for microphones. one "flagship" or a collection?

Could probably get: Schoeps CMC6 X 2 Gefell UMT 70s x 2 For the budget. Then rent a tuber if I have mission critical vocal recording session.

Upgrade Stereo pair

IMHO, a pair of Schoeps CMC6's with the MK5 (switchable omni and cardioid) caps would be your best bet. The only other combo would be the a pair with MK21 caps.
