Schoeps MK 21 Wide Cardioid Microphone Capsule

With a pattern between an omni and a cardioid, the Schoeps MK 21 wide cardioid capsule joins an omni’s warmth to a cardioid’s directivity.

Its low end is better than a cardioid’s and its proximity effect weaker. Its polar response stays very consistent across the frequency range, so direct sound and reflections from the side are picked up without added coloration.

It is often used as a soloist or main microphone, and as a main pair, for example 30 cm apart at ±45°. As a spot microphone it goes slightly closer to the source than a cardioid would. Its low directivity leaves too little level difference for XY, while M/S and near-coincident pairs often work well. It screws onto the CMC 6, CMC 1 U, or CMC 1 L amplifier.
