The KMIT's sound quality is the same as that of the CMIT 5/MiniCMIT, apart from slight differences in high-pass filtering that depend on which amplifier is being used. The choice among CMC 6, CMC 1 U/L or CMD 42 will mostly be determined by practical circumstances - the size and weight of the setup, and the availability of an AES42 input.
Among the analog amplifiers, Schoeps generally recommends the CMC 1 due to its small size, optimal interference protection, and high maximum sound levels. The CMC 1 L amplifier with miniature Lemo connector allows for an especially compact setup; the CMC 1 U has a somewhat longer, standard XLR connector. The CMC 6 amplifier is likewise compatible - and with the CMC 6 xt version, signals up to 40 kHz can be recorded for "downpitching" sound-design applications.
The digital CMD 42 amplifier offers the greatest number of options, but requires an AES42 input. The CMD's Remote App (available free of charge for iOS or Android phones) allows all three filters of the CMIT 5 to be enabled in the CMD 42 as well.
The built-in, steep high-pass filter allows the KMIT to be used unproblematically on a boom. The steepest cutoff occurs when a CMC 1 is used; the CMC 42 offers a further, additional high-pass filter with an adjustable cutoff frequency.
