Premium Components - Elite Build Quality - Superior Sound

WA-12-B-60V CEK12-Style Capsule

The WA-12-B-60V CK12-style capsule accurately matches the frequency response of the original capsule found in vintage C12 mics. This capsule captures incredible detail across the 30Hz-20kHz frequency response. With a remarkably flat response until the top-end boost starts to hit around 3k, the capsule inside the WA-CX12 will help you capture natural sounds with some added top-end smoothness before the pleasant 19kHz rolloff.

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-CX12 is American-made with large-core German laminations and built to exacting standards as designed by Oliver Archut. The custom transformer drives the full natural sound captured by the capsule delivering that renowned Austrian sound.

Premium Tubes, Capacitors, & Boards

The WA-CX12 uses a premium 12AY7 vacuum tube that adds warmth and depth to the microphone’s signal. Like all Warm Audio products, we use premium capacitors in the circuit for ideal signal transfer. The PCB board in the WA-CX12 does not have solder masks which allows for the lowest noise floor possible, preventing crosstalk from added capacitance.

Authentic Appearance, Elite Build Quality, Premium Accessories

The WA-CX12 is encased in an ultra-durable nickel-plated brass body. Every WA-CX12 comes with a custom tweed carrying case housing the mic, wood mic case, premium Gotham 7-pin cable, IEC cable, shockmount, and external power supply. Every WA-CX12 is meticulously hand-inspected at Warm HQ in Austin,TX by real musicians and engineers with a passion for superior sound.
