Product overview
The SCHOEPS CMC 1 KV is the version of the small Colette microphone amplifier CMC 1 with a fixed, laterally attached cable and a magnetic back, for easy mounting with the included magnetic accessories.
The CMC 1 KV is identical to the CMC 1 U, but instead of the built-in XLR connector it has a fixed cable coming out of the side, and unlike the CMC 1 K its cable leaves at the side instead of the front. It is a fully-fledged alternative to the well-known CMC 6 and compatible with all existing MK capsules and active Colette accessories, for example the CUT 60 or RC.
The CMC 1 KV is particularly suitable as a plant microphone in film sound and for every recording in which the microphone needs to be discreetly hidden. With the supplied magnetic accessories it mounts easily on many surfaces, such as door frames, steel beams, windows and table tops. The standard version has a 2 m cable with XLR-3M; two 0.5 m versions with a 3-pin Lemo plug work with pocket transmitters that provide P48 or P12.
