Wide cardioid, perfect when you’re not trying to zero in on a specific part of an instrument – especially grand piano or large ensemble ambient miking applications. If you’ve got a couple of minutes to delve deeper, check the blurb from DPA below:
– Low profile – wide pickup area
– Natural reproduction
– Directional ambience pickup
– Exceptional for vocal
The phantom powered DPA 4015A wide cardioid differs in its polar pattern and is the perfect fill-in between an omni and a more directional microphone. Sometimes a conventional cardioid pattern just isn’t quite open enough, such as when recording instruments with complex radiation patterns. In those instances, the generous polar pattern of DPA Compact Wide Cardioids allow you to pick up a broader sound field and more accurately capture the full breadth of a stirring performance.
Recording orchestras or other ensembles sometimes requires a compromise between blending in the room reverberation and a more precise localisation. The wide cardioid (also known as hemispheric) design covers a greater sound angle and is an excellent choice for 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.
The off-axis characteristics of the 4015A 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.
DPA’s wide cardioid microphones are capable of handling extremely high sound pressure levels before clipping occurs. The 4015A even includes a 20 dB pad switch in the center of the XLR connector to prevent overloading of the mic amp.
For a more compact version, choose 4015C. Other microphones in the Reference Standard series include 4006A (omni), 4011A (cardioid) and 4017B (shotgun, with filters).
