Warm Audio WA-47F FET Condenser Microphone
No Sound Too Loud. A Secret Weapon Of Pro Studios. The WA-47F is a faithful recreation of a high-SPL, low-noise classic celebrated as a 'secret weapon' across world class studios. The original U47 FET was released in 1969 and gained massive popularity inside recording studios for its ability to handle fast transients and high SPLs. The high SPL handling, especially for a condenser mic, meant that engineers could make kick drums sound huge, and it meant that engineers no longer had to compromise between volume and detail with certain sources.
Full Volume. Powerful Detail. No Compromise. Like all Warm Audio microphones, the WA-47F is a no-nonsense studio tool with premium components and elite build quality. Like the originals, the WA-47F takes the sound of the WA-47 tube mic and swaps the valve for solid-state FETs, meaning there’s no compromise between capturing rich midrange, detailed bass, and handling very loud sources. At its core, the WA-47F uses a premium reproduction of the vintage K47-style capsule found in the original microphone for ultra-wide frequency response and detail. The WA-47F uses a single backplate, cardioid-only version of the same capsule used in our award-winning WA-47 tube microphone. The capsule is joined by a custom TAB-Funkenwerk USA Output Transformer that drives the punchy, powerful sound captured by this capsule. The WA-47F pairs premium Fairchild FETs with polystyrene & Wima capacitors and the AMI output transformer, giving the WA-47F the ideal frequency response to capture extra detail and depth. The -10dB pad gives you extra headroom for those loud sources that you need to keep loud. When you need to eliminate unwanted bass frequencies on sources like lead vocals or electric guitar cabs, engage the included 140 Hz low-cut filter to save yourself from unnecessary post-EQ. Our meticulous R&D process allowed us to dial in a true-to-original output level and frequency response that matches the performance expectations of world-class audio engineers and recording facilities.
