The A127 is designed to capture the most accurate and purest form of acoustic instruments and sound sources. Fundamental to the A127 design is the low-noise Type 1 metal film capsule and precision-machined electro-mechanical components. The A127 delivers unmatched performance for recording, broadcast, film and sound design. With frequency response of 10Hz-20kHz and wide dynamic range of 133dB the A127 excels in the most demanding applications.
Capsule design features a precision-tuned 3-micron metal diaphragm, resulting in exceptionally accurate and stable response with ultra low self-noise of 7dBA. The A127 circuit is designed and built to exacting specifications and is coupled to the capsule by a series of driven shields to protect the microphone from external interference and capacitance coupling. The mechanical components of the gold-plated shield and the corrosion-resistant housing are precision-machined by Audix in Wilsonville, Oregon.
