Overview

The Warm Audio WA-47jr is a large-diaphragm condenser microphone that draws its sonic inspiration from the legendary '47 studio microphone — a design heard on countless hit records over the past half century. Rather than using a vacuum tube circuit, the WA-47jr employs a fully discrete, transformerless FET topology that captures much of the warmth and body associated with the original while eliminating the need for a dedicated power supply or tube maintenance. At the heart of the microphone is a gold-sputtered, dual large-diaphragm capsule built on a single backplate with 6-micron NOS Mylar film, engineered to deliver the smooth top end and rich midrange presence that made the '47 a vocal recording standard.

Three switchable polar patterns — cardioid, figure-of-eight, and omnidirectional — make the WA-47jr adaptable to a wide range of studio applications, from close-miked lead vocals and acoustic guitar to room ambience capture and mid-side stereo recording. A -10dB pad allows the microphone to handle high-SPL sources like brass, drums, and guitar amplifiers without distortion, while the 70Hz high-pass filter cleans up low-frequency rumble before it reaches your recording chain. Finished in nickel with a solid, professional build, the WA-47jr positions itself as a versatile workhorse microphone for project studios, home recording setups, broadcast booths, and live sound applications where classic tonal character matters.

Warm Audio WA-47jr — Editorial Review

The Warm Audio WA-47jr is an affordable, transformerless FET take on the classic Neumann U47 FET, built around a large-diaphragm capsule. It aims to deliver a large slice of a vintage studio standard's character at a fraction of the cost.

U47 FET inspiration on a budget

MusicTech and Everything Recording describe a rugged, well-made cardioid condenser with a fairly neutral voicing — not overly bright like many budget condensers — that captures crisp highs and works across vocals, piano, drums, and more, with a generous accessory kit (shock mount and bag). It's widely summarized as delivering much of the FET 47 character for far less. In Podcastage's review and test — featured above — the WA-47jr is compared against the WA-47, WA-67, and U67.

Honest cons

  • Not the tube WA-47. It lacks the valve sibling's low-end weight and instant gravitas.
  • Upper-mid character. Some reviewers hear a slightly nasal or "closed" quality on certain lead vocals.
  • Light low-mids. It can want for low-mid body without complementary processing.
  • Cardioid only. A single fixed polar pattern — no omni or figure-8.

Where this microphone fits

  • Home and project studios wanting a U47-FET-flavored large-diaphragm condenser affordably.
  • Multi-instrument recordists capturing vocals, acoustic guitar, piano, and drum overheads.
  • Creators who like a neutral-leaning condenser they can shape in the mix.
  • Not those needing the tube WA-47's heft, multi-pattern flexibility, or a guaranteed flattering lead-vocal sound on every voice.

Frequently Asked Questions

It provides three switchable polar patterns — cardioid, figure-of-eight, and omnidirectional — selectable via a switch on the microphone body, giving you flexibility for different recording scenarios.
No, the WA-47jr uses a solid-state FET (field-effect transistor) circuit with a fully discrete, transformerless design. It captures the tonal character of the classic '47 without requiring an external power supply or tube maintenance.
It features a gold-sputtered, dual large-diaphragm capsule with a single backplate and 6-micron NOS Mylar (PET film), which contributes to its warm, detailed sound character.
Yes, it includes a -10dB pad for handling loud sources without distortion, and a 70Hz high-pass filter to roll off low-frequency rumble such as air conditioning noise or floor vibrations.
Yes, it requires standard 48V phantom power supplied from your audio interface, mixer, or external preamp.
