SCHOEPS CCM 2 COMPACT OMNIDIRECTIONAL MICROPHONE

The Schoeps CCM 2 Compact Omnidirectional Microphones include the CCM 2, CCM 2H, CCM 2S, and the CCM 2XS. Omnidirectional microphones can be considered sonically optimal if realised as true single-diaphragm systems – which is what we at SCHOEPS do. Their strengths include exceptionally linear frequency response with extended low-frequency response and a low noise floor (in the case of SCHOEPS – even as low as 11dB(A)). The various types of omni capsules differ in the amount of high-frequency boost, which compensates for the high-frequency roll-off in the diffuse field. Thus, omnidirectional microphones can be free- or diffuse-field equalised. We offer a free-field and a diffuse-field version along with two others, which lie in between. CCM 2 This microphone type has flat frequency response for frontal sound incidence. This yields a very natural quality when picking up sound that is predominantly direct, i.e. close to the source or in a ”dry” acoustic. omnidirectional linear frequency response corrected for the direct sound field for use close to the sound source (frontal sound incidence) preferred applications: close pickup of singers and instruments This microphone can also be ordered as a modular Colette microphone, where the CMC 1 L amplifier is combined with an MK microphone capsule. (CMC 1 L   MK 2) This variant allows the capsule to be exchanged and has advantages in terms of electrical properties in combination with digital wireless transmitters. CCM 2H If this microphone is used indoors at medium recording distances (i.e. where direct sound energy is similar in amount to reflected sound energy), its overall response will be linear. Its extended frequency response and low noise make it appropriate for the most demanding applications. The sound inlet of the CCM 2H is narrower than that of our other pressure transducers, causing a slight, purely acoustic response elevation above 6 kHz. This reduces the high frequency loss for diffuse sound, thus helping to preserve natural sound quality. omnidirectional pattern mild high-frequency rise to compensate for losses at medium recording distance often chosen for spaced stereophony and Decca Tree arrangements This microphone can also be ordered as a modular Colette microphone, where the CMC 1 L amplifier is combined with an MK microphone capsule. (CMC 1 L   MK 2 H) This variant allows the capsule to be exchanged and has advantages in terms of electrical properties in combination with digital wireless transmitters. CCM 2S The 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. The frequency response characteristic of the CCM 2S falls between that of the CCM 2 and the CCM 2XS, making this microphone suitable for a wide range of applications. omnidirectional pattern slight high-frequency rise to compensate for losses at moderate recording distances for a very wide range of recording applications often preferred for spaced stereophony and Decca Tree arrangements This microphone can also be ordered as a modular Colette microphone, where the CMC 1 L amplifier is combined with an MK microphone capsule. (CMC 1 L   MK 2S) This variant allows the capsule to be exchanged and has advantages in terms of electrical properties in combination with digital wireless transmitters. CCM 2XS The CCM 2XS (formerly CCM 3) is designed for placement in a diffuse sound field, i.e. at distances in reverberant environments where the greater portion of arriving sound has already been reflected from various room surfaces. In such placement the integrated frequency response of this capsule is essentially flat; the on-axis high-frequency response elevation shown in the graph below is not heard as such. It is remarkable how well-focused a recording can be made with omnidirectional microphones at such distances, when the microphones have been designed and placed appropriately. But when sound arrives from nearby sources in front of the capsule, high frequencies are distinctly accented, leading to a sound image with special brilliance. If this type of microphone is used close to the sound source, the emphasis of high frequencies for on-axis sound incidence would become clearly audible, producing an overly brilliant sonic impression. Since most recording today is miked more closely than in decades past, microphones such as the CCM 2S or CCM 2H are a reasonable norm for the majority of spaced-omni and “Decca Tree” applications. But if miking distances more typical of the mono and early stereo era are to be used, a capsule such as the CCM 2XS, with its full diffuse-field equalization, may well offer the optimal balance of focus, depth and spaciousness – and the KA 40 accessory spheres can then add a further measure of presence to the sound at such distances, if desired. The CCM 2XS is also often used as an ambient room microphone. omnidirectional pattern diffuse-field equalised capsule for miking distances at which the predominant sound is no longer direct useful for relatively distant placement in reverberant environments – as a room microphone, for spaced stereophony and in Decca Tree arrangements This microphone can also be ordered as a modular Colette microphone, where the CMC 1 L amplifier is combined with an MK microphone capsule. (CMC 1 L   MK 2XS) This variant allows the capsule to be exchanged and has advantages in terms of electrical properties in combination with digital wireless transmitters.   CCM 2 Frequency range see corresponding capsul Sensitivity see corresponding capsul Maximum sound pressure level (THD < 0.5 %) 135 dB-SPL (P48) 127 dB-SPL (P12) Maximum output voltage 2,6 V (8,3 dbV) with 2 kΩ load Low cut filter 20 Hz, 12 dB/Okt.
