The Schoeps MK21H is part of the Colette series of modular capsules designed for use with the CMC preamplifiers. The MK21H provides a wide cardioid polar pattern that provides a uniform response around the front hemisphere of the capsule. The polar pattern effectively reduces ambient noise and feedback. At the requests of pop musicians and vocalists, the MK21H's unique signal characteristic is a rise in high frequency response of +4dB at 7KHz. The high frequency shelf is consistent all the way to 20KHz, resulting in a cardioid response that emphasizes high-end brightness and intelligibility.
