The CMC 6 is Schoeps’ most popular amplifier.
Its electrical properties have set new standards in terms of low distortion levels and common mode rejection (i.e. suppression of interference induced in the microphone cable).
The capsules of condenser microphones can’t be connected directly to microphone cables or inputs; a microphone amplifier is required in between. Thus a complete microphone of the Colette series comprises any of the twenty available types of capsules combined with an amplifier. The CMC 6 U is designed for standard 48- and 12-Volt phantom powering. Its circuitry recognizes the supply voltage and adjusts itself automatically. Its performance characteristics remain essentially the same either way; mainly, the difference is that the current drawn at 12 Volts is greater than at 48 Volts. However, the 12-Volt mode consumes less power and might be preferred for battery-powered recording.
The microphone amplifier is responsible for providing the necessary electric charge to the capsule, without which it would be unable to generate a signal. Since the capsule’s output signal is very weak (Hi-Z), it must be amplified. In order for the microphone’s output to cleanly reach the next stage in the signal chain, it must undergo balancing and impedance matching before transmission. The CMC 6 incorporates a balanced, direct-coupled class-A amplifier, yielding a low output impedance, high RF shielding, and minimal distortion.
- flat frequency response
- very low harmonic distortion and noise
- works with 12V and 48V phantom power
- balanced, low-impedance output
- high suppression of interference on the microphone cable
- excellent protection against high-frequency radio interference with “RFI Shield”
- frequency-independent impedance
- signal transmission possible over very long cables
- reliable operation even with weak phantom power
- symmetrical, transformer- and capacitor-free output stage with a class-A amplifier
- above 20 kHz, the signal is attenuated for protection against interference in the ultrasonic range, e.g. through the ultrasonic autofocus of a film camera
- Includes SG 20 stand clamp
