The DPA ST4011C is a complete DPA 4011C Stereo Pair with two carefully factory-matched first order cardioid microphones. Whenever a small, lightweight, inconspicuous microphone for top-quality sound is required, the compact design and uniform unidirectional response of our versatile 4011C makes it the perfect choice. They are particularly popular as spot mics for classical recording and on-stage close mics for live sound. Even though the standard tolerances on DPA Reference Standards are extremely low, a stereo match is even closer. The specially selected DPA 4011C 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.
