Large-diaphragm Tube Condenser Microphone - 3 Switchable Polar Patterns, Highpass Filter, and 10dB Pad

The Warm Audio 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 every 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. We 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 our WA-47 sonics to sit right in with these 2 vintage '47 mics. We are pleased to release such a gorgeous sounding classic to the market at a price that's reachable to more people than ever before. We are also proud to mention that the WA-47 sounds legitimately indistinguishable to the vintage '47's we auditioned on several sources.

As with all Warm Audio products, we focus heavily on quality components to ensure we 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.

True '47 style capsule
The WA-47 utilizes 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. We are proud to be using such a faithful recreation of this classic part in an affordably priced '47 style microphone.
The WA-67 utilizes a custom re-production of the vintage '67-style (K67) capsule that was used in the classic microphone - complete with the same hole pattern and frequency response. We even went the extra mile to ensure that our capsule adheres precisely to the vintage specs, evidenced by the fact that the assembly is made entirely out of brass, including the tensioning hoops. The capsule is one of the most important pieces of the classic '67 formula, and we're ecstatic at how it turned out.

The EF86 vacuum tube is well known in the audio industry for having characteristics that are seriously flattering to audio sources - in fact there are a number of boutique manufacturers that use it in their ultra-expensive microphones and preamps. The tube has a unique character that is both vibey and hyper-accurate at the same time, and even though that sounds a bit odd to say, you'll understand when you hear it. Offering a microphone of this quality, based around an EF86 tube - at this price - is unheard of in our industry, and we couldn't be happier to make it available to recordists everywhere!

The WA-67 utilizes a custom large-core transformer made by Lundahl in Sweden, a company well-known for making killer transformers for some of the top names in audio. The transformer is another component that is critical to the sound and performance of the WA-67, and it helps provide the creamy smooth high frequency response and girth that this mic will undoubtedly become famous for.

The quality of the 7-pin cable that connects a tube mic to its power supply is also of paramount importance - it carries both audio and voltage for the tube on different pins, which means that it plays an integral role in the performance of the microphone. That's why we've partnered with high-end manufacturer Gotham Audio of Switzerland to use their high-end GAC-7 cable with the WA-67. This special cable adds the finishing touch to the WA-67 system, and is integral to the sound and performance of the microphone.

The WA-67 proudly uses high-bandwidth polystyrene capacitors, as well as boutique capacitors from Wima throughout, and an imported Solen French capacitor on its output.
