The Type 3506-A is a complete A-B Stereo Kit with two carefully factory-matched phantom powered (P48) condenser microphones. The 3506-A also includes a Stereo Boom and the complete range of DPA Acoustic Modification Accessories, all in a sturdy carrying case with a foam insert. The specially selected microphones Type 4006 are matched within 1dB on both frequency range, sensitivity and self noise. The maximum phase response difference from 50Hz to 20kHz is 10?. The high sensitivity, the low noise-floor and the extremely linear frequency response from 20Hz to 20kHz (-2dB) of the microphone pair makes the 3506-A the perfect choice for all professional A-B Stereo recordings
