Warm Audio releases WA-47 Tube Condenser Microphone

WA-47 Tube Condenser Microphone

New Product From Warm Audio - In Stores (First Week of December 2017)

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 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.

The Capsule: The WA-47 utilizes a custom reproduction of the vintage 47-style capsule that was used in the classic ‘47 microphone - designed with the same hole pattern and frequency response. Our version of this capsule (model# WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer, and its precision allows us to nail the sonics for the most important sonic piece of the microphone.

The Tube: A Slovak Republic JJ 5751 vacuum tube is a lower gain, low noise tube that forces much of the sonics of the capsule and transformer to be heard more significantly than some higher gain tubes might allow. We auditioned 4 different tube brands and fell in love with the JJ 5751. The frequency response of the JJ and the way it contributes to the circuit is tonally smooth and vintage in nature.

The Transformer: An American made TAB-Funkenwerk (AMI) USA transformer with large core imported German laminations is used in the WA-47. This transformer helps provide the creamy smooth top end, and the LARGER THAN LIFE bottom end one would expect from a 47-style condenser microphone.

The Cable: One component of a tube microphone that is often overlooked is the 7 pin cable that connects the microphone to its power supply. When auditioning the WA-47 and other tube microphones we learned quite a bit about 7 pin cables and how the shielding and wire gauge size can drastically change the sonics of a tube microphone. We have partnered with Gotham Cable in Switzerland to use their very carefully built top-end 7 pin GAC-7 cable. Using this cable increases top end presence and the overall size of the recorded image in the stereo field, by reducing phase shift and the parasitic effect of poorly built cables. Gotham Cabling is very expensive and boutique in nature and should be considered no small addition to the WA-47 package.

The Capacitors: The WA-47 proudly uses a polystyrene coupling capacitor for uncompressed top-end response from the capsule, wima film capacitors throughout, and an imported Solen French capacitor on its output driving the TAB-Funkenwerk (AMI) USA transformer.

We at Warm Audio are very excited to bring this all vacuum tube, large diaphragm, transformer balanced, multi-pattern (9), large condenser microphone to the market at such an affordable price. We feel confident that you will enjoy a lifetime of beautiful recordings with the WA-47.
