Warm Audio WA-47jr Condenser Microphone (Nickel)

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.

Quality components make a better mic.

Warm Audio WA73 Microphone Preamp 

A Single Channel '73 For The Rest Of Us

If there’s one style of preamp that professional engineers would unanimously agree has defined the tone of pop/rock records for decades, it would most definitely be the venerable '73-style of mic pre. '73-style preamps have been massively used in recording and live applications for many years and are still considered to be the “Holy Grail” of preamp choices today. The Warm Audio “WA73 Family” consists of single and dual channel '73-style preamps (with & w/out EQ), that each pay careful homage to British audio history.

When we at Warm Audio decided to release the WA73 it was imperative that it met vintage expectation in both design and performance.  The tone and sweet character that vintage '73-style mic preamps impart is so unique and familiar, that we had only the pure desire to release sonically accurate reproductions. After years of R&D, careful reverse-engineering, and countless hours of auditioning, the WA73 has been born!

The WA73 is a “Desert Island” boutique preamp, but it can also be classified as a studio and live work-horse.  Classic '73-style preamps are known for being versatile tools that work with all kinds of microphones from Condenser, to Dynamic, to Ribbon.  The WA73 equally shines on all types of microphones and sources including; vocals, acoustic/electric guitars, bass, drums, percussion, orchestras, keyboards, and even as a tone shaping tool to run partial or complete mixes through.  With 80dB of gain and a fully discrete Carnhill Transformer balanced signal path, there’s no recording, mixing or engineering task that the WA73 can’t handle.

Hand Wired & Hand Assembled

Classic '73-style preamps were often hand-wired and so is the WA73!  Guru’s claim that a portion of the sought after classic British tone can be attributed to the hand-wired nature of the build.  The WA73 is hand-wired and hand assembled, including the pcb components that are all populated by hand.

UK Custom Carnhill Transformers

Enthusiasts unequivocally get excited about the components used in classic '73-style British preamps.  The signal transformers are a common topic of conversation.  Vintage units used various versions of transformers throughout the years, but the most coveted were the earliest versions.  These are regarded as the most desirable choice due to their fluid and forgiving nature.  They saturate sweetly when pushed, and have been known to make engineers cry when they hear how beautiful their mixes sound through them! Warm Audio worked closely with Carnhill Transformers of Cambridgeshire, UK, to design faithful reproductions of these most coveted, early version transformers.  We at Warm Audio have not yet heard a modern day '73-style preamp sound as sweet and musical as does our WA73 with these beautiful custom Transformers.

Capacitors & Signal Path

An important part of classic British tone not often discussed are the different styles of capacitors and output transistor used in '73-style circuits.  We found it important to maintain integrity to early British designs by using tantalum and polystyrene capacitors in the signal path and an output transistor choice that is much smoother in the high gain settings than what is typically found in modern '73-style preamps.
