Warm Audio WA-47jr Large-Diaphragm FET Condenser Microphone (Black)

Warm Audio WA-47jr Overview

Warm Audio WA-47jr Condenser Microphone is a large-diaphragm FET condenser microphone designed to provide the tonal characteristics of classic solid-state U47 microphones for vocalists, musicians, and recording engineers in home, project, and commercial recording studios. Thanks to warm audio wa-47jr three polar patterns—cardioid, omnidirectional, and figure-8—selectable from a switch on the front of the body, its versatility allows it to excel at anything from dry, close-up vocals to ambient room sounds. And A -10 dB pad switch raises the maximum SPL from 147 dB to a high of 157 dB, enabling safe use when miking kick drums and cranked guitar and bass amps. Excessive low frequencies from the proximity effect are easily reduced via the high-pass filter, which rolls off lows below 70 Hz.

The K47-style capsule reproduction features dual gold-sputtered, 6-micron Mylar diaphragms with a single backplate. The fully discrete signal path includes Toshiba FETs, WIMA film capacitors, and Panasonic electrolytic capacitors to deliver the clean tone associated with transformerless microphones. With a gold-plated XLR 3-pin connector and operability via 48V phantom power, it is compatible with most mixing consoles and mic preamps. It comes with a vibration-reducing shock mount and a compact hard mount to allow flexibility in placement and positioning.

Custom Capsule

The Warm Audio WA-47jr Condenser Microphone Large Diaphragm FET utilizes a custom reproduction of the vintage K47-style capsule that was used in the classic U47 microphone—designed with the same pattern and frequency response. Because Warm Audio’s version of this capsule (model WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer who’s precision and consistency allow sonic replication of the most important piece of this classic style of microphone.

Low Noise

The Warm Audio WA-47jr Condenser Microphone Large Diaphragm FET discrete signal path pairs with the true U47-style capsule to obtain a very similar tone to the classic U47 microphone. The low self-noise of only 9 dBA enables pristine capture of quiet sound sources.

Tone-Impacting Components

The Warm Audio WA-47jr Condenser Microphone Large Diaphragm FET incorporates a modernized and simplified circuit design. Toshiba FETs, WIMA film capacitors, and Panasonic electrolytic capacitors contribute to the signature tone of the mic.

Configuration Flexibility

Three polar patterns and a -10 dB pad enable versatility for close and distant positions and loud and quiet sources. The 70 Hz high-pass filter aids in reducing rumble, proximity effect, and excessive low frequencies.
