DPA 4003 Stereo Kit (matched pair)
The Type 3503 is a complete 4003 Stereo Kit with two carefully factory-matched omnidirectional hi-voltage (130 V) condenser microphones. 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.
