Product Overview

A microphone package that includes a CMC 6 amplifier, MK 41 supercardioid capsule, SG20 stand clamp, and 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 41 is strongly directional. Sound arriving from off axis is attenuated even more than with a cardioid. The pickup is 'drier' and less susceptible to acoustic feedback than any other SCHOEPS microphone type, provided that a loudspeaker is not located directly on the rear axis of the microphone. Its directivity is highly independent of frequency, so that even sounds arriving off axis and reverberant sound are registered without coloration. Consequently, even distant placement of the microphone produces a very natural sound pickup. This is a real advantage over interference-tube shotgun microphones, whose directivity is very frequency-dependent – exceeding that of a supercardioid only at higher frequencies. Interference-tube microphones are notoriously sensitive to their position in a room, where the shifting patterns of reflections cause corresponding shifts in sound color. Thus the MK 41 is surprisingly effective and a space-saving alternative to shotgun microphones – and being small, it can often be placed closer to the sound source. An M/S microphone arrangement can be set up at quite some distance from the sound source if an MK 41 is used for the "M" channel. Compared to the cardioid MK 4, the supercardioid has slightly more rolloff at the low end due to the gradient effect. Its high-frequency linearity both on- and off-axis also gives it a less brilliant sound than the MK 4.

Features

  • CMC 6 Microphone Amplifier
    • Flat frequency response very low harmonic distortion and noise
    • Works with 12V and 48V phantom power balanced
    • Low-impedance output high suppression of interference on the microphone cable
    • Excellent protection against high-frequency radio interference with "RFI Shield"
    • Frequency-independent impedance signal transmission possible over very long cables
    • Reliable operation even with weak phantom power symmetrical
    • Transformer-free and capacitor-free output stage with a class-A amplifier
    • Above 20 kHz, the signal is attenuated for protection against interference in the ultrasonic range, e.g. through the ultrasonic autofocus of a film camera
  • MK 41 Microphone Capsule
    • Supercardioid directional pattern
    • High directivity, at low and medium frequencies comparable to that of a shotgun microphone
    • Natural sound due to flat frequency response which remains largely the same for all directions of pickup. This is particularly important for indoor recording
    • Preferred uses: recording dialogue for film sound; as a spot microphone in the orchestra and on the opera stage
