Schoeps CMC65 ST Colette Modular Microphone - U.S. Stereo Set. (2) CMC6 with MK 5 Omni/Cardioids, A20 or A20S Suspensions, B5 Popscreens. Matte gray (g) or nickel (ni) finish.
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.
Schoeps CMC6 Features :
- Balanced, very low-impedance output
- Can be used with very long cables (several hundred meters)
- Can be used with Active Accessories for miniaturization and special applications
- Collette modular microphone system amplifier.
- 12V-48V Phantom Power and Balanced Output.
- Surface finish in Matte gray (g) finish.
Schoeps Microphone Capsule MK 5 Features :
- Omni and cardioid patterns for lateral pickup thats very well maintained throughout the frequency range
- Mechanically switchable pattern selector
- Slight high-frequency boost for emphasis and to help improve intelligibility
- Broad range of applications - Ideal for music, speech, and universal applications
- Surface finish in Matte gray (g) finish.
The MK 5 operates with only one membrane, but offers two selectable directional patterns. The pattern is selected purely by mechanical means, via a slide switch on the side of the capsule.
In its omnidirectional setting the capsule is a pressure transducer with flat response down to the lowest audio frequencies. The polar diagram shows increasing directivity at high frequencies, which is typical for this type of transducer.
In the cardioid setting equal components of pressure-gradient and pressure operation combine to form a cardioid pattern. (Please make certain that the pattern selector is definitely in one position or the other; in-between settings will yield undefined results.)
The fact that response is maintained to the highest audible frequencies is unusual for a switchable-pattern microphone.
The MK 5 has a slight high-frequency emphasis as compared with the corresponding single-pattern omni (MK 2) and cardioid (MK 4). The MK 5 has near-universal usefulness and it is the capsule which we recommend most highly for those just starting out with the Colette Series.
The MK 5 omni / cardioid microphone type has the most general applicability and is one of the types most widely used.
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. Thats why Schoeps recommends the CMC 6, which works with both 12 V and 48 V phantom powering so long as the relevant standard is followed.
