DPA 3503 Complete 4003 A-B Stereo Kit

Included is also the High-Voltage Microphone Amplifier HMA5000, a Stereo Boom and the complete range of DPA Acoustic Modification Accessories, all packed with cables in a handy carrying case with a foam insert.

The specially selected microphones are matched within ±0,5 dB on both frequency range, sensitivity and self noise. The maximum phase response difference from 50 Hz to 20 kHz is 5°. The two 4003 microphones are acoustically identical with the studio standards Type 4006 and even have an extended low frequency handling capability (-2 dB at 10 Hz) which also is supported by the ultra-transparent Microphone Amplifier HMA5000.

The high sensitivity, the low noise-floor and the extremely linear frequency response from 10 Hz to 20 kHz (±2 dB) of the microphone pair makes 3503 the ultimate choice for all professional A-B Stereo recordings.
