Schoeps CMC66G-SET

A microphone package that includes a CMC 6 amplifier, MK 6 three-pattern capsule, SG20 stand clamp, and a B5 popscreen. Available in gray.

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. It features a symmetrical class-A output stage with neither coupling condensers nor an output transformer. This design helps it to achieve extremely low distortion and light physical weight, while its very low output impedance helps make it insensitive to electrical interference. The CMC 6 works with both 12 V and 48 V phantom powering so long as the relevant standard is followed. In addition to the CMC 6's dual-voltage circuitry, the two amplifiers differ in their response at the very bottom of the audio frequency range. The CMC 6 is essentially flat to 20 Hz.

The MK 6 operates with a single diaphragm. When the ribbed cap of the capsule is rotated, a system of internal shutters alters the acoustic chambering around the diaphragm to change its characteristic from omni to cardioid to figure-8, then back through cardioid to omni. (There is no functional difference between the two available cardioid settings.) In the omnidirectional setting it is a true pressure transducer with flat response down to the lowest frequencies. In this setting the MK 6 shows an increasing directivity toward the high frequencies which is typical for such a transducer. As with the MK 8, the 0° axis is perpendicular to the body of the microphone and is indicated by a red dot at the lower rim of the capsule. A black dot marks the 180° direction. As with any microphone whose switchable patterns include the figure-8, the frequency response is neither as flat nor as extended in the high-frequency region as with the capsules described earlier. However, in the figure-8 setting, the MK 6 closely resembles the MK 8.

Note:
Though not specifically designed for such use, the MK 6 capsule can also be used on the RC Active Tube or the variable angle joint GVC; when fully tightened it will rarely be aimed where you intend. On request Schoeps will supply an elastic ring which can be slipped over the threads of the RC or GVC so that the final turn of the capsule will place it at the desired angle of rotation.
