The “Open Cardioid” directional pattern, occupying a point on the spectrum between the wide cardioid and classic cardioid patterns, was developed by SCHOEPS in 2008. The response is -5 dB at 90° and there is 16 dB suppression of rear-incident sound. It is in essence a variant cardioid which balances a very natural sound quality with a good degree of directionality.
The years of experience which many recording engineers have had with the various types of Schoeps cardioid microphones have played a large role in the design process. The MK 4 cardioid is often relied upon as a reference microphone, even in difficult recording situations; its sonic transparency and outstanding suppression of rear-incident sound make it a universal problem-solver. The MK 21 wide cardioid offers an alternative when its lower directivity fits the recording situation, e.g. for the first desk of strings or for solo piano. This capsule type is prized for its sonic character (similar to that of a pure omnidirectional microphone) and its relative lack of proximity effect. Then the wish arose for a “middle way” which would combine these characteristics into a single capsule. The result is the MK 22 Open Cardioid.
- New kind of directional pattern: “Open Cardioid”
- Optimal combination of classic cardioid directionality (MK 4) with the Directional pattern largely constant throughout the frequency range
- Often preferred for spot miking and as a soloist’s microphone
The Schoeps CMC 6 Amplifier is designed for standard 48- and 12-Volt phantom powering. Its circuitry recognizes the supply voltage and adjusts itself automatically. Its performance characteristics remain essentially the same either way; mainly, the difference is that the current drawn at 12 Volts is greater than at 48 Volts. However, the 12-Volt mode consumes less power and might be preferred for battery-powered recording.
- Flat frequency response
- Extremely low noise and distortion
- Balanced, very low-impedance output
- Can be used with very long cables
- Well-protected against RFI
- For use with 12- or 48-Volt phantom powering
The two amplifiers in a stereo pair of microphones should be of the same type. On request, Schoeps can select ”matched pairs” of capsules with equal sensitivity and frequency response for critical applications, at slight additional cost.
