DPA d:dicate� ST4015A Stereo Pair with 4015A Wide Cardioids
|
|
Product Code: ST4015A
 |
� Wide pickup area and natural sound
� Ambience pickup with some directionality
� Carefully matched within �1 dB
� PeliTM Case transportation and protection
Recording 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.
Included in this kit
Two carefully matched 4015A wide cardioid microphones, sturdy PeliTM case,
holders, and windscreens. |
