The Warm Audio WA-47Jr FET Condenser Microphone is an FET transformerless condenser microphone featuring three polar patterns and a 20Hz-20kHz frequency range. The WA-47Jr is fully discrete and designed for pro studio, home studio, live and broadcast applications for a range of instruments and vocals. The WA-47jr utilises a custom k47-style capsule reproduction, designed with the same hole pattern and frequency response as the vintage design.
The WA47Jr's low-noise and discrete signal path, when paired with this excellent true '47 style capsule, allows it to obtain a very similar tone to the classic ‘47 microphone. The WA-47Jr circuit uses high quality Toshiba FET’s, Wima film capacitors and Panasonic electrolytic capacitors. The circuit is modernised and simpler than the classic ‘47 tube microphone.
