Description
The DPA 4006A Omnidirectional Microphone is a benchmark in transparent, high-definition audio capture. Revered as a global recording standard, this microphone has earned its status through over 25 years of exceptional performance in studios, concert halls, and out in the field. With its outstanding neutrality and precise detail, the 4006A captures the full depth and dimension of any source, making it an essential tool for sound engineers working in demanding field recording environments.
Whether capturing immersive ambience, natural soundscapes, or orchestral performances in situ, the 4006A excels with its clear, uncolored sound and high sensitivity. Its ability to reveal subtle textures and dynamics makes it ideal for critical applications—from wide stereo A-B setups to detailed spot miking of instruments or environmental elements.
What truly sets the 4006A apart for field recordists is its modular flexibility. With interchangeable acoustic accessories—including nose cones and grids—it can be tailored to different acoustic conditions without introducing phase shift or distortion. This adaptability ensures consistent, professional-grade results in any recording scenario.
