Warm Audio WA-47 Tube Condenser Microphone

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.

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.

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

AMI Transformer

The Warm audio 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.

Tone-Impacting Capacitors

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.
