This type of microphone has a low-frequency roll off to compensate for the low-frequency boost which occurs when close-miking. It is used primarily in voiceover and sound reinforcement applications, and wherever good speech audibility in a noisy environment is a prime requirement.

Microphone Capsule for close pickup
– Cardioid for very close speech pickup (under 10 cm)
– Low-frequency response rolloff (-10 dB at 100 Hz)
– Polar diagram identical as the MK 4
– Preferred applications: close speech pickup, public address systems
This cardioid capsule is designed for the very closest speech pickup, i.e. directly in front of the speaker’s mouth.
Its low-frequency rolloff is compensated by proximity effect. Thus it has (up to the point of its high-frequency emphasis) a flat frequency response for the speaker’s voice, while showing a rolloff at low frequencies for all sound that originates from a greater distance. As a result, background sounds are picked up less strongly than the person speaking.
