Warm Audio WA47 Tube Condenser Microphone

The WA-47 is an all vacuum tube, large diaphragm, transformer balanced, multi-pattern (9), large condenser microphone, based on the classic ‘47 that has been used on countless hit records for the last 50+ years. The WA-47 is designed for pro studio, home studio, live, and broadcast applications and sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments, and an array of other sources. The classic ‘47 became extremely popular in the 1960’s and is now considered one of the greatest microphones ever made. The classic ‘47 is still widely used today in professional recording studios but have become extremely rare and expensive to acquire.

Designing the WA-47 to sound like the classic ‘47 was no easy task, especially considering that some of the vintage components are no longer available. Warm compared and listened to 2 different vintage ‘47 mics and found that they both sounded amazing but also sounded a little different from each other. These comparison tests became the benchmark for tailoring their WA-47 sonics to sit right in with these 2 vintage ‘47 mics. They are now pleased to release such a gorgeous sounding classic to the market at a price that’s reachable to more people than ever before. Warm are also proud to mention that the WA-47 sounds legitimately indistinguishable to the vintage ‘47’s they auditioned on several sources.

As with all Warm Audio products, the focus is heavily on quality components to ensure they release the best sounding product possible. The WA-47 is packed with top end components that are carefully sourced from many of the top pro audio component suppliers in the world.

The WA-47 utilises a custom reproduction of the vintage k47 style capsule that was used in the classic ‘47 microphone - designed with the same hole pattern and frequency response. Every Warm Audio capsule is made in the same small assembly house in a clean-room environment, and packaged in its own protective jewel case until the moment it is loaded into the microphone. Each capsule is visually inspected and electrically tested for imperfections.

A large part of any microphone's tone comes from its capsule, and the true k47 style capsule used in the WA-47 is not easily manufactured or typically found in affordable condenser microphones. Warm are proud to be using such a faithful recreation of this classic part in an affordably priced '47 style microphone.
