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 is faithful to the original production run from 1953-1963, and serves as the basis for the historically accurate sound profile. Like the original, the WA-CX12 tone is mostly flat until a slight dip at 2kHz with a gradual boost between 5-10kHz. At the beginning of the chain, the CX12 has an edge-terminated, all-brass CK12-style capsule, that stays true to the frequency response of the original-run 12-style microphones. This capsule allows the WA-CX12 to have 9 polar patterns with the typical cardioid, omni, and figure-8, in addition to 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, getting the most out of the capsule and additional circuit components. The WA-CX12 has premium capacitors throughout, and a no-solder mask board for the lowest noise possible. As with all Warm Audio products, we focus heavily on quality components to ensure we release the best sounding product possible.
