Description

The RK-47 is a clone of the original K47 mic capsule used in the Neumann U47 and U47 FET microphones. The RK-47 is an affordable upgrade or replacement to fix imported microphones that have a harsh, sibilant frequency response. It’s also a suitable choice for DIY builds of the U47, 47 FET, and others.

Is your inexpensive mic harsh, peaky, and sibilant?

Many inexpensive microphones imported from China use an inexpensive K67 or K87-style capsule that is a bad fit for the microphone’s circuit. The K67/K87 design by Neumann is a classic, but it has a very sharp peak in the upper range that needs corrective EQ (usually provided by the microphone’s circuit). The unfortunate truth is that most budget microphone manufacturers try to clone the Neumann capsule but neglect to design their circuit with corrective EQ, and furthermore, use low-quality components that are critical to the audio signal path.

The K47 comes to the rescue.

The Neumann K47 capsule has a flatter frequency response when compared to the Neumann K67/K87. This makes it an ideal fix for your harsh and peaky inexpensive microphone.

The RK-47 is a single-backplate, double-sided microphone capsule, featuring 3-micron mylar sputter with gold, and produces balanced frequency response with mild push between 3 and 5 kHz.
