DPA ST4015A Stereo Microphone Kit
DPA ST4015A Stereo Microphone Kit
DPA ST4015A Stereo Microphone DetailsRecording orchestras or other acoustic ensembles sometimes requires a compromise between blending in the room reverberation and a more precise localization. The wide cardioid (also known as hemispheric) design covers a greater sound angle and is also an excellent choice for grand piano, guitar, marimba, and percussion, or as a spot mic for groups in a symphony orchestra.
The DPA ST4015A is a complete DPA 4015A Stereo Pair with two carefully factory-matched wide cardioid microphones. Even though the standard tolerances on DPA Reference Standards are extremely low, a stereo match is even closer.
The specially selected DPA 4015A microphones are matched within ±1 dB on both frequency response and sensitivity.
The foam design in the heavy-duty transportation box allows for fast and easy exchange of microphone/accessory inlays.
