Description

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.
