Audix A127 Reference Omnidirectional Condenser Microphone

Overview of Audix A127 Reference Omnidirectional Condenser Microphone

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. 

Features:

• Pre-polarized half-inch Type 1 metal film capsule (IEC 61094-4 compliant)
• Omnidirectional polar pattern
• Excellent clarity, detail, and transient response
• Transformerless, low-noise circuitry
• Active driven shield
