The Audix A127 is a reference-grade omnidirectional condenser microphone designed to accurately capture the purest form of acoustic instruments and sound sources. Featuring a 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. Its capsule design includes 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.
