The d:facto™ is designed specifically for  performing vocals on stage and features a supercardioid capsule designed to reproduce every nuance of the human voice transparently, consistently and carringly. Two versions are available. The d:facto™ Linear Vocal Microphone (4018VL) is extremely linear. The d:facto™ Vocal Microphone (4018V) is linear, but with a high-end boost. The 4018V is often chosen because it "comes through" on a television set where content is typically transmitted to built-in television speakers with limited audio quality.

Except for the linearity/amplification, these microphones are identical. Both feature an isolation-optimized supercardioid polar pattern. This directional pattern offers the best of both worlds - of cardioid and supercardioid patterns. These microphones can pick up loud voices with a three-stage pop-protection grille and best-in-class noise performance. They also provide excellent sound reproduction with full detail and balanced linear phase and frequency response that users have come to trust in DPA microphones.

A supercardioid microphone is similar to a cardioid - it is most sensitive to sound coming from the front, and least sensitive to sound coming from the rear. Supercardioid microphones usually have a much narrower angle of sensitivity - so they are even more bundled than a "normal" cardioid microphone. This off-center sound is more or less colored and attenuated - and the narrow angle of focus significantly increases the range of attenuated sound. However, the unique DPA capsule technology avoids the coloring of sound coming from the sides or back of the microphone, and merely reduces the sensitivity to these angles, providing perfect sound stages. The amount of attenuation depends on the exact specifications of the microphone.

Because of their nature, supercardioid microphones are often used on the live stage - both at concerts and spoken events, to capture the focused sound of an instrument or voice. The narrow sensitivity angle helps keep other sounds from becoming too prominent on a busy stage. With supercardioid microphones, note the proximity effect, which causes an increase in bass response the closer the microphone is placed to the sound source. Also, supercardioid microphones are much more sensitive to wind, pop, and handling noise than omnidirectional microphones, so you should take appropriate precautions.
