Schoeps CMC 6 U | Microphone amplifier
637,81€

- constant frequency response
- Very low distortion
- for operation with 12 V or 48 V phantom power
- completely balanced signal routing, especially low impedance output
- safe against RF interference with “RFI Shield
The CMC 6 is Schoep’s most popular microphone amplifier. Its signal routing is completely symmetrical. The electrical characteristics of the CMC 6 set standards in terms of its low distortion and unbalance attenuation.
Microphone capsules of condenser microphones cannot be operated directly on microphone cables or inputs. This requires the interconnection of a microphone amplifier. Each MK capsule of the Colette series must therefore be screwed to a microphone amplifier and only together with it forms a complete microphone.
The CMC 6 U can be operated on 12V and 48V phantom power. The circuitry of the CMC 6 U automatically detects the supply and adjusts to it. Their properties remain essentially unchanged – only the current is adapted to the supply voltage. This is higher at 12V than at 48V. Nevertheless, the power consumption is lower at 12V, which is advantageous for battery operation.

CMC Microphone amplifier
In addition to the standard version of the CMC 6 U and 6 xt U, the following variants are available on request:
CMC 6 linear (No. 193002)
The CMC 6 microphone amplifier has a lower cutoff frequency of 20 Hz to keep infrasonic noise of various origins, e.g. due to air currents or vibrations, low. However, when using pressure receivers, there may be a desire to record frequencies below 20 Hz without attenuation. The CMC 6 linear allows this. On request, it can be supplied with a lower cut-off frequency of 10 Hz. Caution: Since pressure receivers also pick up infrasound down to very low frequencies, even noise from ventilation systems or rail vehicles can become problematic in large rooms, e.g. churches. The danger is even greater with pressure gradient receivers. Although they transmit the lowest frequencies from the sound field only weakly, they react all the more violently to other, undesirable stimuli such as air movements and structure-borne sound. Although these signals are outside the audible range, they can cause strong, audible distortion due to overdriving, especially of inputs with undersized transformers.
CMC 6 U +5 dB (No. 193001)
Microphones with such marked amplifier are 5dB more sensitive than the standard version. The limiting sound pressure level is reduced by 5dB and the disturbance-free voltage range decreases slightly. Using this version can still be advantageous if you need to boost the microphone signal above the noise level of the connected device, or if you usually record rather low levels. Otherwise, it is more likely to overload the input of the connected device or the microphone amplifier itself at high sound pressure levels.
