The chief task of a CMC microphone amplifier is to convert the extremely high-impedance signal from the capsule to a very low-impedance one suitable for transmission through a microphone cable. Several versions are available which differ only in their powering, connectors, output levels and surface finishes. They all feature a symmetrical class-A output stage with neither coupling condensers nor an output transformer. This design helps them to achieve extremely low distortion and light physical weight, while their very low output impedance helps make them insensitive to electrical interference.
On the choice of amplifier type:
If a recording device has balanced inputs but lacks phantom powering, it may be possible to add 12 Volt powering rather easily by using a supply voltage that is already present internally. In most cases 48 Volts would need to be generated with a voltage multiplier circuit, which is more difficult to implement. That is why we recommend the CMC 6, which works with both 12 V and 48 V phantom powering so long as the relevant standard is followed.
MK 41 Modular Capsule: The MK 41 is strongly directional. Sound arriving from off axis is attenuated even more than with a cardioid. The pickup is ‘drier’ and less susceptible to acoustic feedback than any other SCHOEPS microphone type, provided that a loudspeaker is not located directly on the rear axis of the microphone.
Close-speech Guard B 1: Very thin foam cover for CCM Compact Microphones. When picking up violins with the VA 1 violin adapter, it serves as a protection of the microphone against rosin deposit.
SGC: Clamp made of gray plastic material – the unobtrusive, esthetic standard version
