Warm Audio WA-47jr FET Condenser Microphone

The Contemporary Version of a Classic Sound

The WA-47jr FET offers one of the most coveted classic microphone capsule designs in an affordable microphone circuit. The WA-47jr FET uses a high-quality discrete transformerless circuit with Toshiba FET's, Wima film capacitors, and Panasonic electrolytic capacitors. The WA-47jr FET brings the tone and character of the classic '47 style microphone to you through the most critical component (its capsule) and is able to maintain an aggressive price point by simplifying the rest of the circuit topology.

The WA-47jr FET's simplified circuit is in no way a low-quality circuit but is simpler to build and uses fewer components than a vintage tube microphone, which allows Warm Audio to offer it at such a bargain price. The WA-47jr FET uses the same capsule as Warm Audio's flag-ship WA-47 tube microphone and sounds wildly similar to the WA-47.


The Past Meets the Present

The Warm Audio WA-47jr is a microphone that truly delivers vintage sound with modern versatility. This mic can be used in any setting, from a small project studio to a top-tier live room run by Grammy-nominated engineers. To achieve the WA-47jr's signature sound, Warm Audio honors the past and embraces the present. The heart of the mic is the custom gold-sputtered, dual large-diaphragm, single backplate K47-style capsule, which captures warm and rich sound.

The premium Toshiba FETs provide even more top-end information compared to the original U47-style tube microphone, resulting in a more pristine sound in the upper register. The WA-47jr also boasts boutique-grade polystyrene, Panasonic electrolytic, and WIMA film capacitors, allowing for exceptional signal transfer throughout the microphone. Plus, it has a completely discrete signal path with no ICs, just real-deal analogue circuitry.

The WA-47jr's versatility is further enhanced by its three selectable polar patterns: cardioid, omnidirectional, and figure-8. These directional patterns offer elite rejection of unwanted noise, making it ideal for capturing a wide range of sources. The mic also features a switchable -10dB pad, which enables it to handle high SPLs up to 157dB, making it a great choice for louder sources like toms, guitar cabs, and overheads.

Additionally, the 70 Hz Hi-Pass filter can filter out unwanted low-end rumble at the source, making mixing much easier. The rigorous R&D process for the WA-47jr ensures that it meets the performance standards of world-class audio engineers at an unheard-of price point.


Elite Versatility, Vintage Sound

Recording quality audio is a nuanced art form that requires a keen ear and versatile tools. The WA-47jr is a professional studio microphone that is highly adaptable and versatile, making it the go-to choice for capturing a wide range of instruments and vocals.

From soaring vocals to pounding drums, delicate strings to raucous horns, the WA-47jr has been used to capture it all and bring the "sound in your head" to life. Its ability to excel in a variety of recording scenarios is a testament to its exceptional design and build quality. Here are just a few ways that engineers and artists have used the WA-47jr to achieve fantastic results and take their recordings to the next level.

Vocals - The original 47-style tube microphone is a timeless choice for capturing huge-sounding vocals, so it’s not surprising that the WA-47jr is a fantastic choice as a versatile vocal mic that can deliver on a variety of vocal styles. The slight peaks right before 5kHz and after 10kHz give vocals recorded on the WA-47jr pleasing high-end and a little extra radio-ready polish.

Drums - Toms - Dynamic microphones are known for handling higher SPLs without issue and having excellent unwanted noise rejection. Many working engineers have used the WA-47jr on toms due to their ability to replicate those exact qualities (high SPLs and great peripheral noise rejection) but with the pristine detail of a multi-pattern condenser microphone.

Drums - Overheads - As overhead mics, a pair of WA-47jr's is a lot like combining the best of both worlds. The rich depth of the K47-style capsule combined with the pristine top end from the FET circuit gives you a mic that captures brilliant cymbal sounds without sacrificing any detail recording the entire kit from above.

Acoustic Guitar Body - When choosing the right microphone for acoustic guitar, it’s important to understand whether you are going for a darker tone, a brighter tone, fingerpicking, flatpicking, strumming, or mixed playing. The WA-47jr excels at combining the warmth and depth of vintage-voiced microphones with a little added air on the top end. This works great when the desired guitar sound should be full-bodied with added presence on the top.


Premium Components - Elite Build Quality - Superior Sound

WA-47-B-50v Capsule - The WA-47-B-50v capsule is a true reproduction of the large, dual-diaphragm K47-style capsule and the same capsule in the award-winning WA-47 tube microphone. This capsule captures authentic analogue detail across the 20Hz-20kHz frequency response. With the warmth of the capsule combined with extra top-end information from the FET, the WA-47jr will be right at home on many sources.

Toshiba Transistors & Premium Capacitors - The WA-47jr uses premium Toshiba transistors that deliver professional audio fidelity. The WIMA film capacitors and Panasonic electrolytic capacitors in the WA-47jr provide critical signal conversion, allowing the 47jr to get the full benefit of the K47-stye capsule with the added top-end boost from the Toshiba FETs.

Patterns, Pads, and Filters - The WA-47jr is a multi-pattern mic with available cardioid, omnidirectional, and figure-8 patterns. A selectable -10dB pad allows it to handle SPLs up to 157dBs, making capturing loud sources easy. Engaging the 70 Hz Hi-Pass filter helps filter unwanted bass rumble and noise at the source instead of playing with potentially tone-destructive EQ during the mixing process.

Authentic Appearance & Elite Build Quality - The WA-47jr is encased in an ultra-durable nickel-plated brass body. Every single WA-47jr is meticulously hand-inspected at Warm HQ in Austin, TX by real musicians and engineers with a passion for superior sound.
