A127 Omnidirectional Reference Microphone

Whether you’re setting up a pro-level studio or your home setup, you’ll need a reference mic to measure the characteristics of your room. Our go-to reference microphone is the Audix A172. It showcases an incredibly flat frequency response, ensuring that you get the most accurate results possible. Audix didn’t stop there, however. This omnidirectional condenser microphone doubles as a high-definition recording mic. It has an ultra-low self-noise of just 7dBA, enabling it to capture any acoustic source in all its glory. Plus, it handles high SPLs like a champ. If you’re in the market for a new reference microphone, the Audix A127 can do it all.

You may be reading this and saying to yourself, “A reference mic for recording? How can that be?” Audix designed the A127 to be much more than a standard reference microphone. They loaded it with a pre-polarized, half-inch metal film capsule for ultra-accurate frequency response and with very little self-noise. It can handle up to 140 dB SPL, making it an excellent choice for almost any source. Throw a stereo pair above a piano, orchestra, or drum kit, and you’ll be impressed with the results.
