WARM AUDIO WA-47JR SE

Warm Audio WA-47jr SE – Cardioid FET condenser microphone inspired by the legendary U47, Junior Studio Essential Mic Series

The Warm Audio WA-47jr SE is a contemporary take on the renowned “47-style” large-diaphragm studio microphone. Designed to recreate the rich, expressive analog tone of the legendary U47, it adopts a modern transformerless design for enhanced transparency and extremely low self-noise. Thanks to its gold-sputtered K47-style large-diaphragm capsule — the very same used in the tube model WA-47 — the WA-47jr SE captures the warmth and texture that shaped recordings by The Beatles, Billie Eilish, Harry Styles, and Adele.

Featuring a fully discrete FET circuit built with premium components (Toshiba transistors, Wima film capacitors), this mic blends vintage warmth with exceptional modern clarity. Its fixed cardioid pattern makes it ideal for vocals, acoustic and electric guitars, or percussion, offering precise, natural results. The WA-47jr SE stands out with an ultra-low self-noise of 9 dBA and a 138 dBA dynamic range, ensuring pristine recordings even with the loudest sound sources.

Compared to the original WA-47jr, the SE version focuses on simplicity and efficiency: it features a single cardioid polar pattern for more intimate, focused recordings while maintaining the same high-end audio performance. In contrast to the WA-47 tube version, it offers greater transparency and easier maintenance while sharing the same U47-inspired sonic philosophy.
