The Schoeps CMC 1 U is a Collette series miniature preamp for mic capsules such as the MK41 or MK8. Its discreet size means it is perfect for situations where size and weight of the microphones comes into play.
The CMC1U includes a premium case and an SG20 mic clamp.
CMC 1 U Uncompromising Quality
The CMC 1 U does not compromise on quality. Schoeps' promise of “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
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 Schoeps CMC 1 works with standard 12-Volt or 48-Volt phantom powering. Power consumption is lower at 12 Volts--an advantage for battery-powered operation.
