The DPA 3506A Stereo Kit with matched 4006A Omnidirectional Microphones is a premium solution for capturing crystal-clear, reference-grade stereo sound. Revered in high-end recording and film production, this kit is designed for professionals who demand unmatched sonic transparency and natural detail across a wide range of applications, from orchestral performances to field recording.
At the heart of the kit are two factory-matched 4006A omnidirectional condenser microphones, carefully selected to within ±0.5-1 dB on both frequency response and sensitivity. These phantom-powered microphones offer an ultra-linear frequency response from 10 Hz to 20 kHz (±2 dB), extremely low noise, and high sensitivity. ideal for A-B stereo configurations and capturing subtle sonic textures with precision.
The 3506A kit includes windscreens, a stereo boom, clips, holders, and a full range of accessories such as interchangeable grids and acoustic pressure equalizers. These components allow acoustic tailoring of the mic without introducing phase shifts or distortion, delivering the most versatile and accurate stereo capture system available.
