Authentic Reproduction Of The Most Coveted Mic For Timeless Studio Sound

Timeless Studio Sound

The WA-47 is an authentic reproduction of the most coveted tube condenser microphone, hailed for its timeless studio sound. The WA-47 accurately matches the sonic profile of the prized vintage originals delivering the deep bass, rich midrange, and smooth highs that made it a favorite of legendary recording artists like Frank Sinatra, Johnny Cash, Ella Fitzgerald, Billie Holiday, Elton John and many more.

A Proper Recreation Of A Studio Legend

The WA-47 is designed and built to deliver the most authentic vintage 47-style sound with zero corners cut. Just like the original, the WA-47 circuit allows a lot of low-end and mid detail to come through. While the lows and mids come together to capture all the rich warmth and detail of acoustic instruments, vocals benefit greatly from the smooth and pleasing top end of the WA-47. The coveted and unmistakably vintage sound profile of the WA-47 makes it the perfect choice to create timeless music.

Key Features

Like the original 47-style mic, the WA-47 includes all the features that deliver a complete and professional recording experience.

The WA-47 uses a true reproduction of the K47-style capsule in the original 47 tube mic. Perfect for recordings where vintage vibe is a must.

The custom USA-made AMI transformer drives the bold sound captured by the capsule, delivering the full body, warmth, and richness out of the WA-47 circuit.

The premium 5751 vacuum tube in the WA-47 delivers rich analog tone with exceptionally low gain - ideal for intimate recordings, especially on vocals.

The WA-47 has three key polar patterns - Cardioid, Omni, & Figure-8. Six additional patterns in-between provide ultimate flexibility and versatility for a variety of recording applications.

K47-Style Capsule

The custom K47-style capsule in the WA-47 is a true reproduction of the large, dual-diaphragm K47-style capsule found in the original U47 mic. This capsule captures authentic analog detail across the 20Hz-20kHz frequency response. With just the right peaks where most vocals sit, the capsule inside the WA-47 will quickly make this a favorite mic for vocals and any source where vintage vibe is a must.

AMI USA-MADE Output Transformer

The history of TAB-Funkenwerk (AMI) transformers goes all the way back to the founding of the most sought-after German analog audio innovations. The TAB (AMI) transformer in the WA-47 is American-made and built to exacting standards as designed by Oliver Archut. The sweet sonic character of the WA-47 would not be possible without the amazing, historically-correct transformer supplied by TAB-Funkenwerk.

Premium Tube & Capacitors

The premium 5751 vacuum tube in the WA-47 delivers true analog tone with exceptionally low gain and (11dBA) self-noise. Premium polystyrene, WIMA, and Solen French capacitors are used throughout the WA-47 circuit, providing the excellent signal conversion that this circuit demands.

Hand-Tested, Elite Build Quality

The WA-47 is encased in an ultra-durable nickel-plated brass body with an updated headbasket shape adding additional space around the capsule. Every single WA-47 is meticulously hand-inspected at Warm HQ in Austin,TX by real musicians and engineers with a passion for superior sound.

Affordable, Clean and does the job.
Size: 36 sqft, Size: 36 sqft
I consumed about 90% of this box doing all doors and the tailgate on a 2000 tahoe. I applied it very liberally inside every door (exteror) panel. We then added an almost equal amount of deadening/absorbing/decoupling foam to the other side of the door (panel side). If you know how many rattles a circa 2000 tahoe GMT800 can have by now, you can appreciate why I added this as a "must" if i were to put some money back into this vehicle. Best sub $150 spent on this mini resto so far, right next to tint. Good quality. Not to thick or thin. Good sized sheets. Seamed to deaden as good as another slightly thicker material i recently used in my F250. My box was delivered with no issues of melting or anything funky. Clean, no major smell before or after and easy to work with. Maybe buy a roller set and wear gloves. Save your hands if your doing inside of panels. Good buy. Will buy more for future projects.

AS GOOD AS ANY OTHER, WORKS GREAT
Size: 36 sqft, Size: 36 sqft
Used this in my 17 RAM 1500. This stuff works great, just as good as S...ss brand that is also sold on here. Same thickness and same tackiness. And this stuff sticks like crazy, once its laid down and rolled onto the surface, it is hard to remove, so I am pretty sure it will stay where I installed it. It is great value, one box was enough to do the whole roof of the truck with a little left over for small spots. I think it took a total of 2.5 boxes to do my whole crew cab, roof, floor and back wall and most of the firewall, and I also added a layer of their .25" foam. I do notice a difference in less outside noise, from wind and road. I will be doing my wife car soon, and this is the product I will be using again, I recommend this.

Awesome, inexpensive alternative to name-brands!
Size: 36 sqft
Awesome. Stuck well with alcohol prep and time to let liquid flash-off. Very consistent, piece to piece. Backing peeled easily when desired. Compared to Amazon Basics, the butyl seemed a little thicker (infinitesimally) and stickier, foil was less thick than Amazon Basics. Very good value. Started with my nice car, but after completing project, sound dampened all cars in the immediate family it made such a noticeable difference in sound level and quality of music from soeakers. Recommended!
