Description
The Warm Audio WA-47 is a premium black-finish tube condenser microphone that faithfully recreates the legendary “47-style” sound, delivering the iconic tone heard on countless classic recordings. Designed to bring vintage character to modern studios, this large-diaphragm, transformer-balanced microphone captures vocals and instruments with rich detail, smooth top end, and a powerful, larger-than-life low frequency response. With nine selectable polar patterns-including cardioid, omnidirectional, figure-8, and intermediate options-the WA-47 offers exceptional versatility for studio, broadcast, and live applications.
At its core, the WA-47 features a custom K47-style capsule built to vintage specifications, paired with a premium TAB-Funkenwerk (AMI) USA transformer for authentic analog warmth and depth. A carefully selected 5751 vacuum tube enhances the microphone’s smooth, vintage response while allowing the capsule and transformer to shine. The result is a balanced, natural sound that excels on vocals, guitars, drums, piano, strings, and brass instruments. Every component-from the capsule to the circuitry-has been meticulously chosen to recreate the sonic character of the original while maintaining modern reliability.
The WA-47 comes as a complete professional package, including a dedicated power supply with voltage selector and polar pattern control, a boutique Gotham GAC-7 7-pin cable for superior signal transfer, a shockmount, IEC power cable, and a protective wooden storage box. Designed with premium components such as polystyrene and WIMA capacitors, this microphone delivers consistent, high-quality performance. Combining timeless tone with modern craftsmanship, the WA-47 is an essential addition to any studio seeking classic analog sound with dependable functionality.
