Frequently Asked Questions - Colette CMC641 Schoeps
What is the Schoeps Colette CMC 641?
The CMC 641 is the amplifier/preamp section of the Schoeps Colette modular microphone system. It provides the necessary electronics (phantom-powered, transformerless) and includes a switchable low-cut filter and -10 dB pad. The attached capsule determines the polar pattern and frequency response.
Which capsules can I use with the CMC 641?
The CMC 641 is compatible with all Schoeps Colette series capsules, such as MK 4 (cardioid), MK 41 (supercardioid), MK 5 (switchable), MK 2 (omnidirectional), and others. Simply twist and lock the capsule onto the amplifier.
How do I power the CMC 641?
The CMC 641 requires standard 48V phantom power (P48) according to IEC 61938. It can be supplied by any mixing console, audio interface, or dedicated microphone preamp with phantom power. Current consumption is typical 4 mA.
What are the settings of the low-cut filter and pad?
The low-cut filter rolls off frequencies below 80 Hz with a slope of 12 dB/octave. The pad (attenuation) reduces the signal by 10 dB. Both are activated via small slide switches on the amplifier body.
How do I clean and maintain the CMC 641?
Use a soft, dry cloth to wipe the exterior. Avoid water, solvents, or compressed air. The capsule grille can be gently brushed. For deep cleaning, consult a Schoeps service center. Store in a dry, dust-free environment.
Can the CMC 641 be used outdoors?
Yes, with appropriate protection (e.g., a windscreen and shock mount). The operating temperature range is -10°C to +50°C. However, avoid direct exposure to rain or high humidity, as the electronics are not waterproof.
What is the expected lifespan of the CMC 641?
With proper use and care, the CMC 641 can last decades. Schoeps guarantees availability of spare parts for 10 years after discontinuation, and repairs are possible through authorized service centers.
Does the CMC 641 have balanced output?
Yes, the output is balanced via a 3-pin XLR male connector. The output impedance is 15 ohms, allowing long cable runs with minimal signal loss.
What is the difference between CMC 6 and CMC 641?
The CMC 6 is the standard amplifier; the CMC 641 is a variant with a different color (often matte gray) and may include slight design updates. Functionally they are identical, both offering the same electronic features.
How do I attach or remove a capsule?
Align the two index marks on the amplifier and capsule, then push and turn clockwise to lock. To remove, press the release button (if present) and turn counterclockwise. Do not force.
