DPA 4015A Wide Cardioid Microphone

DPA 4015A Wide Cardioid Microphone

This mic is the perfect fill-in between an omnidirectional and a directional microphone.

The off-axis characteristics of this mic are totally linear, a unique quality when it comes to authentic sound reproduction. Any leakage that occurs from off-axis sound sources is still a faithful reproduction of these sounds, just softly attenuated.

Sometimes a conventional cardioid pattern just isn’t quite open enough. Recording orchestras, and other ensembles, sometimes require a compromise between blending in the room reverberation and a more precise localization. When recording instruments with complex radiation patterns, the wide cardioid (also known as hemispheric) design covers a greater sound angle and is an excellent choice. This is the ideal mic for recording grand piano, guitar, marimba and percussion, or as a spot mic for groups in a symphony orchestra. Likewise, it is an excellent speech, dubbing, or vocal mic as its enhanced richness on the bass end nicely compliments many voices.

This mic suits acoustic instruments and voices with rich and open sound. It is capable of handling extremely high sound pressure levels before clipping occurs. The 4015A Wide Cardioid Mic even includes a 20 dB pad switch in the center of the XLR connector to prevent overloading of the mic amplifier.
