The WA-CX12 is a professional large-diaphragm tube microphone with premium components, elite build quality, and is hand-inspected in Austin, Texas. The circuit design of the WA-CX12 stays true to the original production run from 1953-1963 and forms the basis for the historically accurate sound profile. Like the original, the WA-CX12 tone is mostly flat with a slight dip at 2kHz and a gradual boost between 5-10kHz. At the start of the chain, the CX12 features an edge-terminated, all-brass CK12-style capsule that remains faithful to the frequency response of the original 12-style microphones. This capsule allows the WA-CX12 to offer 9 polar patterns including the typical cardioid, omni, and figure-8, plus 6 intermediate patterns. Moving down from the capsule, the WA-CX12 uses a premium 12AY7 vacuum tube for added warmth. At the end of the circuit, the WA-CX12 uses a custom TAB-Funkenwerk (AMI) USA Output Transformer, which gives the WA-CX12 a very full, wide, and open sound, maximizing the capsule and additional circuit components. The WA-CX12 features premium capacitors throughout and a no-solder mask board for the lowest possible noise. As with all Warm Audio products, we focus heavily on quality components to ensure we release the best sounding product possible.
