Warm Audio | WA-47 Tube Condenser Microphone | Warm Audio

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. Warm Audio 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 the WA-47 sonics to sit right in with these 2 vintage ‘47 mics, and allowed them to release such a gorgeous sounding classic to the market at a price that’s reachable to more people than ever before.

Features:

  • Custom true '47 capsule reproduction (k47 style) - Model# WA-47-B-80v
  • Capsule makeup: Gold sputtered, dual large diaphragm, single backplate, 6 microns NOS mylar (PET film)
  • TAB-Funkenwerk (AMI) USA output transformer
  • JJ Slovak 5751 vacuum tube
  • Gotham 5 meter GAC-7, 7-pin tube microphone cable
  • Wima, Solen French, and Polystyrene capacitors
  • 9 polar patterns - Cardioid, Omni, figure-of-eight + 6 mixed patterns


The 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. This version of this capsule (model# WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer who's precision and repeatability allows them to nail the vintage sonics of the most important sonic piece of this classic style of 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. The designers auditioned 4 different tube brands and fell in love with the JJ 5751. The frequency response of the JJ 5751 and the way it contributes to the circuit is tonally smooth and vintage in nature.

The Transformer
The WA-47 utilizes an American made TAB-Funkenwerk (AMI) USA transformer with large core imported German laminations. 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 often overlooked is the 7 pin cable that connects the microphone to its power supply. When auditioning the WA-47 and other tube microphones, the design team 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. They partnered with Gotham Audio 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 often found in poorly built cables. Gotham Audio is very expensive and boutique in nature and should not be considered a small addition to the WA-47 package.

The Capacitors
The WA-47 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 output transformer.
