Warm Audio WA-47JR FET Condenser Microphone

Warm Audio WA-47jr
FET Condenser Microphone

The WA-47jr is an FET transformerless version of the highly renowned classic 47 microphone that has been used on countless hit records for the last 50+ years.  The WA-47jr is fully discrete, has 3 polar patterns and is designed for pro studio, home studio, live, and broadcast applications.  The WA-47jr sounds great on vocals, acoustic/electric guitars, acoustic/electric bass, drums, piano, strings, brass/woodwind instruments, and an array of other sources.

 

The WA-47jr proudly utilizes a custom k47 style capsule reproduction, designed with the same hole pattern and frequency response as the vintage design.  Our version of this capsule (model# WA-47-B-80v) is carefully manufactured by an Australian capsule manufacturer with careful precision and repeat-ability that allows the most important sonic piece of the classic mic to be heard and influence the tone and signature of the WA-47jr.  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, but at a much lower price tag.  The WA-47jr utilizes the same k47 style capsule found in our flagship WA-47 tube condenser microphone.

 

The WA-47jr circuit uses high quality Toshiba FET’s, Wima film capacitors and Panasonic electrolytic capacitors.  The circuit is modernized and more simple than the classic 47 tube microphone, but the components and circuitry are top-notch, and have a sound quality and tone that punches far above anything we’ve ever heard in this price range.

​We at Warm Audio are very excited to bring this 47 style FET condenser microphone and classic tone to the market at such an affordable price.  We feel confident that you will enjoy a lifetime of beautiful recordings with the WA-47jr.
