Warm Audio WA-47JR Large-Diaphragm Condenser Microphone

With the same k47-style capsule as Warm Audio's flagship '47 replica, this 3-pattern FET condenser delivers incredibly natural sound at an unheard-of price.

Delivering a classic tone that is great for recording, the WA-47jr utilizes the same k47 style capsule found in Warm Audio's flagship WA-47 tube condenser microphone. For over 50 years the '47 microphone has been used on hit records -- now you can experience that natural sound with the WA-47jr.

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 utilizes a custom k47 style capsule reproduction, designed with the same hole pattern and frequency response as the vintage design. Warm Audio's 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 Warm Audio's 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 read more simple than the classic '47 tube microphone, but the components and circuitry are top-notch.

I snagged a pair of these for a big record, mainly to add a different color for a room sound. I ended up popping them over the drums for a VERY full sound. I could easily pull off a full sound with them and a kick. Cymbals were mellow and smooth, drums full.I tried it next on guitar...really loved it. 5150 heavy thrashier tunes, this added a lot of weight and preserved that high end sizzle clearly. I paired it with a SM57 and an e906--was really pleased with the balance it added.Bass...used it on an Oranged AD200B through an Orange 4x10. Crushed it. Full, deep, clean and clear.And, lastly, because I was so thrilled with, I tried it on vocals. Heavy shouting/screams/growls/clean--for this person it was very full, clear, smooth and far from hyped or jubilant. I even went and tried it after to see how it sounded on my voice, it was wonderful.
