Schoeps CMC 1U – Small Colette microphone amplifier + Schoeps MK4 Cardioid Mic Capsule

The CMC 1 is a 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

A complete Colette-series microphone consists of an MK capsule and a CMC amplifier. 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.

Schoeps MK4 Cardioid Mic Capsule

Features

• classic cardioid
• suitable for the widest range of applications, either as a spot microphone or for stereo recording with coincident, ORTF or M/S microphone arrangements
• with consistent directionality throughout its frequency range
• often preferred for singing or speaking voices and most instruments

The MK 4 is our best-selling capsule. It offers the highest sound quality, flat frequency response, optimal rejection of rear-incident sound, and a directional pattern that remains constant throughout the audio frequency range. In the diffuse sound field it shows only a mild rise around 10 kHz; the sonic impression thus remains free of coloration even when sound is arriving from all sides at once. The sonic impression is thus free of coloration whether sound is arriving at the front or at the sides of the microphone, as well as for diffuse sound (reverberation) in a room.

For those who dare to use their ears rather than just their eyes when choosing a vocal microphone, a Colette microphone using the MK 4 capsule can be a remarkable instrument.

• Although our normal production tolerances are very close, we can deliver specially matched capsule pairs for a small extra charge.

Application

The MK 4 is often preferred by opera singers and other trained vocalists. But its natural, transparent character also suits it very well for use in pop and rock applications, on stage or in the studio, where equalization is a part of the plan. A microphone with a clear, neutral sound quality provides the ideal point of departure whenever special “coloring” is needed.
