Product Overview

A microphone package that includes a CMC 6 amplifier, MK 4 cardioid 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 4 is optimized for maximum rejection of rear-incident sound. Typical of the classic cardioid, at 90° to its axis the attenuation is 6 dB, while from the rear (180°) it can be as much as 30 dB, depending on the frequency. The random-energy efficiency* – the ratio of on-axis sensitivity to diffuse sound field efficiency – is 4.8 dB. (The higher this figure, the less “room sound” is picked up by a microphone, and the less susceptible it is to acoustic feedback.). Due to its directivity, the MK 4 can be placed 1.7 times farther from the sound source than a pressure transducer of equivalent sensitivity, while maintaining the same proportion of direct and reverberant sound. In the diffuse sound field (distant from a sound source in a room, for instance), this microphone type has flat frequency response except for a slight emphasis around 10 kHz. It is ideal for speech as well as for music recordings, with a well-defined sound image free of coloration. When used for X/Y recording or as a Mid microphone in a Mid-Side configuration, it delivers exceptional results. It is also the capsule intended for use with the ORTF stereo microphone (MSTC 64 or STCg).
