Schoeps Stereo-Set CMC 6, MK 21

Schoeps Stereo-Set CMC 6, MK 21 [139003]

The Schoeps Stereo-Set CMC 6, MK 21 contains two complete Colette microphones with matched MK 21 wide cardioid capsules and CMC 6 U microphone amplifiers. It comes with a matching certificate, two stand clamps, two windscreens and a wooden storage case.

Applications

This set suits main-pair ensemble recording where both the musicians and the room acoustics are captured. Use spacing between the microphones for stereo reproduction. The wide cardioid pattern produces insufficient level differences between channels for XY stereo.

Features

• Two MK 21 capsules, matched as a pair and supplied with a certificate.
• Two CMC 6 U amplifiers with separate balanced XLR-3M outputs.
• Modular Colette system with interchangeable MK capsules.
• Automatic adaptation to P12 or P48 phantom power per microphone.
• Schoeps RFI Shield for protection against radio-frequency interference.
