The Warm Audio WA-47 is a large-diaphragm tube condenser microphone designed to provide the tonal characteristics of classic U47 microphones for vocalists, musicians, and recording engineers in home, project, and commercial recording studios. Thanks to nine polar patterns—cardioid, omnidirectional, figure-8, and six intermediate patterns—selectable from the included external power supply, its versatility allows it to excel at anything from close-up vocals to distant room sounds.

The K47-style capsule reproduction features dual gold-sputtered, 6-micron Mylar diaphragms with a single backplate. Tone-enhancing components, including a JJ 5751 vacuum tube, TAB-Funkenwerk (AMI) output transformer, and WIMA, Solen, and polystyrene capacitors, have been carefully selected to impart vintage-flavored tone characterized by a smooth, uncompressed high end and strong, warm low frequencies. Even the 7-pin cable, manufactured by Gotham Audio in Switzerland, rises to meet the demands of uncompromised audio production. It ensures the integrity of high frequencies and minimizes phase shift between the microphone and the power supply.

The WA-47 ships with a wood box and a shockmount, which reduces rumble and decouples it from problematic vibrations.

The WA-47 utilizes a custom reproduction of the vintage K47-style capsule that was used in the classic U47 microphone—designed with the same hole pattern and frequency response. Warm Audio's version of this capsule (model WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer whose precision and consistency allows sonic replication of the most important piece of this classic style of microphone.

The JJ 5751 vacuum tube from the Slovak Republic 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. After auditioning four different tube brands, the folks at Warm Audio fell in love with the JJ 5751. Its frequency response and tonal contributions are smooth and vintage in nature.

The WA-47 utilizes an American-made TAB-Funkenwerk (AMI) USA transformer with imported large-core German laminations. This transformer helps provide the creamy smooth top end and the larger-than-life bottom end one would expect from a U47-style condenser microphone.

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, Warm Audio learned a lot about 7-pin cables and how the shielding and wire gauge can drastically change the sonic characteristics of a tube microphone. Warm Audio partnered with Gotham Audio in Switzerland to use their carefully built, premium 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.

The WA-47 uses a polystyrene coupling capacitor for uncompressed top-end response from the capsule. WIMA film capacitors are present throughout and an imported Solen capacitor drives the TAB-Funkenwerk (AMI) USA output transformer.

Q: 7. Can I use the mic on my iphone at the same time I am recording iMovie on my phone?

A: This mic will not be available for phone calls while using a recording app.

Q: 8. Is there gain control on this product?

A: There is a gain control in the app, not on the microphone. The free Rode app works fine depending on your level and number of recording. Just record a few test recordings, adjust and listen to find that sweet spot.

Q: 9. would it fit a sound devices 788T with CL8 mixer, also would it fit a mixpre 10 II??

A: Yes, the Sachtler Eargonizer Audio Bag (Large) can accommodate the Sound Devices 788T Recorder and CL8 Mixer. As another option, you can use the ORCA OR-32 Audio Mixer Bag (B&H # OROR32).

Q: 10. Can this be used with a regular recorder (with a 1/8 microphone jack) instead of a smartphone (i.e. Olympus Ws-852)?

A: It does with the Rhode adapter. Also, this mic requires power. It did not work immediately with my digital recorder, which is a Roland R-05, as I expected. Upon further examination I realized there was a setting to send power to the mic and it worked like a charm.
