The matte gray MK 5 Microphone Capsule from Schoeps comes as a matched pair, and offers 2 selectable directional patterns, but uses only a single membrane, a no-compromise approach. The fact that full response is maintained to the high audible frequencies is unusual for a switchable-pattern microphone.
In its omnidirectional setting, this MK 5 Microphone Capsule is a true pressure transducer with smooth, extended low-frequency response, low sensitivity to most wind and breath noise, handling noise or mechanical vibration, and no proximity effect. This capsule has a cardioid setting that retains its full directionality even at very low frequencies. The benefits of this design are in its purity and clarity of sound which is immediately audible. This capsule has a slight high-frequency emphasis.
The MK 5 Microphone Capsule is nearly an all-purpose capsule. It is recommended for those starting out with the Colette series.
The pattern selector should be definitely set to one position or the other; in-between settings will yield undefined results.
