Schoeps CMC 1 L Miniature Microphone Amplifier, incl. K 5 LU (5 m cable with XLR-3M plug) and SGC stand adapter.

The Schoeps CMC 1 is the 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.

“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
