In a nutshell

Schoeps CMC 1 (combined here with wide switchable omnidirectional & cardioid MK 5 capsule) is not only a simple 8 cm short sized, lighter (36g vs 60g) version of the famous CMC 6. As for its big brother, the CMC 1 haven't an inbuilt attenuator but it benefits of a 12 db/oct at 20 Hz low-cut filter. This could be very useful for digital recorder mike inputs to avoid quantification noise generated by infra-bass. The CMC 1 power consumption is also radically lowered to 2 mA vs 4 mA at P48, 3 mA vs 8 mA at P12. Its maximum sound pressure level (THD < 0.5 %) is increased (with a MK 4 capsule) from 131 dB-SPL to 135 dB-SPL!
The CMC 1 perfectly enters this family microphones which are very popular on TV stages and in radio studios; they have built their reputation there thanks to a large number of "active" accessories allowing many fittings and combinations. The CMC 1 miniaturization, its precision and its transparency make it a great candidate for stereo pair recording. The CMC 1 microphone preamp can be detached away from MK series capsules via KC active cable (integrating FET) or via GVC swivel which allows the angle between capsule and body axis to be adjusted.

Our recommendations

The MK 5 capsule is omnidirectional or cardioid, with flat response curve for free field sound recording when omni is selected; it is thus advisable to place it, indoors, at a lower distance than room critical radius. Less wind sensitive (in omni position) than its pressure gradient equivalents, it nevertheless requires, like all condensers, the use of a windscreen (foam or polyester basket-type B 20/W 20) when it is mounted on a boom.
