DPA d:dicate� ST4011A Stereo Pair with 4011A Cardioids
|
|
Product Code: ST4011A
 |
� World-wide cardioid reference mic
� Handles very high sound pressure levels
� Carefully matched within �1 dB
� PeliTM Case transportation and protection
4011A cardioids are exceptionally linear in their frequency response � also off
axis, giving you the natural experience. They handle extremely high SPL and will
therefore allow for close placement and are often used for piano recordings with
a placement closer to the hammers or as overheads for drums.
The DPA ST4011A is a complete DPA 4011A Stereo Pair with two carefully
factory-matched first order cardioid microphones. Even though the standard
tolerances on DPA Reference Standards are extremely low, a stereo match is even
closer.
The specially selected DPA 4011A 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 inlay.
Included in this kit
Two carefully matched 4011A cardioid microphones, sturdy PeliTM case, holders,
and windscreens. |
