The Warm Audio WA-47F is a faithful recreation of a classic, large-diaphragm FET microphone celebrated as a "secret weapon" across world-class studios. The original U47 FET was released in 1969 and became wildly popular due to its exceptional ability to handle fast transients and high SPL, great for capturing huge kick-drum and massive guitar-/bass-cabinet sounds. The custom-tuned frequency response and low-noise circuitry help add a pristine edge to solo vocals, rendering sound with meticulous detail—just like the original.

Faithful Recreation of a Classic, No-Compromise Design, Premium Components

The WA-47F offers elite build quality with boutique components (including premium Fairchild transistors) for a no-compromise design. This faithful recreation of a high-SPL, low-noise Classic brings excellent sonic versatility to your recording setup.

WA-47-B-80v K47-Style Capsule

The WA-47F uses a premium reproduction of the vintage K47-style capsule found in the original microphone for a wide frequency response that brings out all the details of your sound—gold-sputtered, large-diaphragm, single backplate capsule

Custom TAB-Funkenwerk USA Output Transformer

The large-core imported German laminations drive the punchy, powerful sound captured by the capsule.

Exceptional High-SPL Handling

Outstanding for kick drums, horns, and cranked guitar/bass amps, the WA-47F easily handles high SPLs up to 137 dB and 147 dB with 10 dB pad engaged.
