d:dicate? ST4006A Stereo Pair with 4006A Omnis - carefully matched microphones - high sensitivity, low noise-floor and extremely linear frequency - PeliTM case transportation and protection The DPA ST4006A is a complete DPA 4006A Stereo Pair with two carefully factory-matched omni microphones. Even though the standard tolerances on DPA Reference Standards are extremely low, a stereo match is even closer. The specially selected DPA 4006A microphones are matched within ±0.5 dB on both frequency response and sensitivity. The maximum phase response difference is 5°. The natural sound, high sensitivity, low noise-floor and extremely linear frequency response from 10 Hz to 20 kHz (±2 dB) of the microphone pair makes the ST4006A the perfect choice for all AB Stereo recordings. The design in the heavy-duty transportation box allows for fast and easy exchange of microphone/accessory foam inlays.
