The Schoeps CMC 6 Colette Microphone Amplifiers include the CMC 6, and CMC 6xt Microphone Amplifier. Schoeps CMC 6 Microphone Amplifier The CMC 6’s 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 recognises 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. Schoeps CMC 6xt Microphone Amplifier, HiRes The CMC 6xt extends the frequency response of the MK capsules up to 40 kHz. Attention was paid to a low self-noise above 20 kHz. This maintains a high level of dynamics when recording at high sampling rates. Thus, the often very small signal above 20kHz is not covered and the noise is still low even after the down pitching. Features: The CMC 6xt is the HiRes version of the CMC 6. Using this amplifier, the frequency range of all axially-addressed capsules (MK 2 H/S, 21, 22, 4, 41, 5) can be extended up to 40 kHz Especially useful when recording with a high sample rate, particularly with the intent to slow down the recording and reduce its pitch by one or more octaves at a later point (e.g. for sound design) CMC 6 MICROPHONE AMPLIFIER Frequency range 20 Hz – 20 kHz Sensitivity see corresponding capsule Maximum output voltage 1 V (0 dBV) with 1 kΩ load Low cut filter 20 Hz, 12 dB/oct.
