Audix A127

The A127 is an onmnidirectional metal film condenser microphone, designed to capture the most accurate and purest form of acoustic instruments and sound sources. The A127 delivers unmatched performance for recording, broadcast, film, and sound design.

With a frequency response of 10 Hz - 20 kHz and a wide dynamic range of 133 dB, the A127 excels in the most demanding applications. Capsule design features a precision-tuned 3-micron metal diaphragm, resulting in an exceptionally accurate and stable response with ultra-low self-noise of 7 dBA. 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.

ADVANTAGES OF THE HALF-INCH FILM CAPSULE The A127 features a reference-grade capsule (Type 1 IEC 61094-4 compliant) with a precision-tensioned metal film diaphragm, providing consistent and reliable performance, even in the most demanding environments. The half-inch size of the diaphragm represents the "sweet spot" for acoustic sound capture, which is why it has become the standard for acoustic measurement. The ultrathin, 3-micron metal film diaphragm provides excellent transient response and a level of detail and realism simply not attainable with conventional diaphragm materials.
