Warm Audio WA47F FET Large-Diaphragm Studio Condenser Microphone

The WA-47F brings the legendary sound of a 1969 studio secret weapon into the hands of modern recording artists and engineers. This faithful recreation of the classic high-SPL, low-noise FET microphone has earned its reputation as a studio workhorse, capturing the performances of icons like Dave Grohl, Daft Punk, David Lee Roth, and Michael Stipe. Unlike popular tube microphones, the WA-47F offers a more pristine top end with tighter, more controllable bass response, making it an essential tool for handling fast transients with exceptional detail.

At the heart of the WA-47F lies a premium reproduction of the vintage K47-style capsule, providing ultra-wide frequency response from 20Hz to 19kHz. The microphone features premium Fairchild FETs paired with polystyrene & Wima capacitors, all driven by a custom TAB-Funkenwerk USA output transformer that captures the punchy, powerful character this capsule demands. The -10dB pad provides extra headroom for loud sources, while the 140Hz low-cut filter helps eliminate unwanted bass frequencies on vocals and guitar cabs without requiring post-EQ adjustments.

The WA-47F excels across multiple recording applications, from capturing massive kick drum sounds to adding pristine edge to solo vocals that need to cut through the mix. Many engineers position the WA-47F on the outside of kick drums to capture the "thump" and air pressure "boom" that dynamic mics often miss, creating a more spatial and alive sound. For guitar and bass cabinets, particularly percussive and loud parts, the condenser capsule’s openness combined with the circuit’s high SPL handling means you can track at serious volumes without compromising detail. Housed in an ultra-durable nickel-plated brass body with an updated headbasket design, each WA-47F is hand-inspected at Warm Audio’s Austin headquarters by real musicians and engineers committed to superior sound quality.
