Pressure-Transducers (Omnis)

無指向

As can be seen from the frequency response curve, this microphone type has a flat frequency response for frontal sound incidence. This yields a very natural sound when recordings are made within the reverberation radius, where the direct sound (frontal incidence) predominates over the reverberant sound (random angles of incidence).

This microphone type can and should be used fairly close to the sound source ? the sound image never becomes overly brilliant or sharp ? and should be directed towards it, since there is some loss of high frequencies in sound arriving off axis.

The MK 2 capsule has qualities of a measurement microphone and is used in acoustimetric applications, where it has gained a considerable reputation.

For calibration with B&K devices a mechanical adapter (type AMBK1, from 20 mm to one inch diameter) is available.

Even from its appearance alone, this microphone type distinguishes itself from the other SCHOEPS pressure transducers: the typical grill is absent, and the sound inlet (surrounded by a gold-plated ring) is smaller than that of other types. These special design features lead to a frequency response that rises only above 6 kHz.

This microphone type would be used in the near field only if a slight high-frequency emphasis were desired. It resembles the MK 2S/ CCM 2S, though the high-frequency emphasis of the MK 2H/ CCM 2H is audibly less pronounced and begins around an octave higher. The primary application for this capsule is at a greater distance from the sound source, e.g. near the reverberation radius, when recording a large orchestra.

This microphone type is particularly designed for the recording of classical music, a field in which it is highly acclaimed. The choice between the MK 2H/ CCM 2H and the equally well-liked MK 2S/ CCM 2S is essentially a matter of personal preference.

The MK 2S or CCM 2S exhibits a slight high-frequency emphasis for frontal sound incidence, with only a slight rolloff of high frequencies off axis and in the reverberant sound field.

This microphone type represents a technically sophisticated and attractive compromise between the two extremes represented by the MK 2/ CCM 2 and the
MK 3/ CCM 3, and is thus close to being universally applicable.

It has been proven particularly useful in two- and three-microphone stereo arrays, where its normal placement near the reverberation radius of the sound field presents a sonically balanced pickup favored by many recording engineers. These models have become our most popular pressure transducers.

With the MK 3 or CCM 3 the aim was to create a microphone type which would compensate for high-frequency losses and brighten the room sound to some extent when placed at a great distance from the sound source. Used in a reverberant sound field, well beyond the source’s reverberation radius in a room, the high-frequency emphasis shown in the on-axis frequency response plot is integrated with the less brilliant off-axis pickup and is not audible as such.

When this type of microphone is used close to the sound source, the emphasis of high frequencies for on-axis sound incidence becomes clearly audible, producing an overly brilliant sound image. Therefore the MK 3/ CCM 3 is most often used as an ambient room microphone, or in special cases when the extra brilliance is desired.
