I just wanted to put in writting my appreciation for everything your company has done for me recently. The replacement for my 664 mixer arrived today and is working perfectly. Please pass on my thanks to Matt for his patience, expert help and the guidance he has provided despite me phoning, in a panic, from various locations around the world. Thanks to you all for going beyond the call of duty, the level of service has been absolutely fantastic!
CMC 6 Ug Mic Amplifier
The capsules of condenser microphones (the only type which SCHOEPS manufactures) 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 Ug 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 provides the electrostatic charge which the capsule requires in order to produce a signal. Since only a miniscule amount of current is contained in this signal, amplification of the current is required. To avoid interference to the signal on the way from the microphone to the input of the mixer or preamp, the signal is conveyed at low impedance and in balanced form. The CMC 6 Ug amplifier offers a symmetrical, transformerless, direct-coupled Class A output stage with low impedance, low distortion, and high freedom from interference.
Please note:
The two amplifiers in a stereo pair of microphones should be of the same type.
