NOW LET'S GET STARTED!
INTRODUCTION
A faithful recreation of one of the most natural and balanced tube condenser microphones of all time, the WA-
CX12 captures the true sound of sources and rooms with extreme accuracy. Used over and over again by some of
the world's most recognized engineers and artists, the original microphone stands out as open, airy, and natural,
making this unattainable classic a staple in any world class recording studio. With no-compromise components and
elite build quality, the WA-CX12 delivers that iconic sound that no personal or professional mic locker is complete
without.
With possibly the most natural sound profile in tube microphones, the WA-CX12 delivers the go-to sound when you
need to capture natural, open audio. While the original is primarily celebrated for its use as a lead vocal mic, ex-
perienced engineers also cite defined bass, organic mids, and polished high end. Making the sound profile of the
WA-CX12 a fantastic choice for several instruments and room-miking techniques. The organic tones from the WA-
CX12 come from precise design methods pairing the CK12-style capsule with the custom large-core TAB-Funken-
werk USA output transformer.
Designing our WA-CX12 to sound like the classic '12 was no easy task, especially since some of the vintage com-
ponents are no longer manufactured or available. We are thrilled to release such a gorgeous sounding, reborn
classic to the market at a price that finally puts a once unattainable sound within reach.
A LOOK INSIDE THE WA-CX12
Solid Brass CK12-Style Capsule
Our carefully engineered CX-12 capsule is an all-brass, edge-terminated capsule that captures all the smoothness,
rich top end, and warm vintage sonics of the original CK12 capsule. The CX12 uses a variant CEK-12 back plate
as a basis, which overcomes manufacturing limitations of the original CK12 capsule. The O-ring and housing of the
CX12 are all machined from solid brass and the diaphragm is 24k gold sputtered 6 micron, NOS PET film (mylar).
The end result is a very consistent, reliable capsule which matches the frequency response and tonality of the clas-
sically spec'd 50s-60s capsule.
The Transformer
The WA-CX12 utilizes a custom, American-made TAB-Funkenwerk Output Transformer. This transformer helps pro-
vide the natural balance in the midrange with just a bit of top-end polish that one would hope to get from a 12-style
condenser microphone.
The Cable
One component of a tube microphone that is often overlooked is the 7 pin cable that connects the microphone
to its power supply. When Warm first started building and auditioning our tube microphones, we learned quite
a bit about 7 pin cables and how the shielding and wire gauge size can drastically change the sonics of a tube
microphone. We have partnered with Gotham Audio in Switzerland to use their very carefully built high-end 7 pin
"GAC-7 cable". Using this cable increases top end presence and the overall size of the recorded image in the stereo
field by reducing phase shift and the parasitic effect often experienced in poorly built cables. Gotham Cabling is a
premium addition and manufactured to exacting standards. The additional durability and improved sound quality
is no small addition to the overall value of the WA-CX12.
