Schoeps CMC 1U Miniature Microphone Amplifier

The CMC 1 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.

Features

• Complete 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.

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

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 works with standard 12-Volt or 48-Volt phantom powering. Power consumption is lower at 12 Volts--an advantage for battery-powered operation

Alignment of vertical capsules with the CMC 1/6:

The CMC 1 U can be used in many suspensions (e.g. OSIX) that have a rigid orientation of the XLR connector and thus the amplifier. Also in the compatible MS and dual MS setups (for example, Cyclone), the alignment is fixed. As a result, the microphone cannot be rotated arbitrarily in such a suspension. For axially aligned capsules like the MK 4 this is not important, but a vertical capsule like the MK 8 has to be aligned radially.
