Wunder Audio CM7 FET Suprema – a professional large-diaphragm phantom-powered condenser microphone representing a modern evolution of the classic U47 FET design. Built to bypass the need for a tube power supply while delivering exceptional performance, the CM7 FET Suprema employs an ultra-low noise single n-channel transistor with JFET technology coupled with a Neve 1073 style mic pre-transformer, overcoming the limitations of 1960s FET transistor technology.
The CM7 FET Suprema delivers stunning results that greatly surpass the original U47 FET, yielding superior low-lows and highs with exceptional clarity and warmth reminiscent of a 1970s era U87. This workhorse studio microphone excels across all sources, particularly vocals, instruments, and a wide range of recording applications. The authentic three-layer grille design features outer large mesh, inner medium mesh, and fine mesh sandwiched between, creating crucial acoustic interplay with the capsule and functioning as a Faraday cage—a key aspect of achieving the correct performance and legendary U47 sound.
The CM7 FET Suprema features a one-piece backplate dual-membrane K47 capsule with individually tuned and matched diaphragms for equivalent response. Taking capsule design one step further beyond vintage specifications, Wunder Audio utilizes a white porcelain ring instead of plastic—providing low permeability and elasticity, considerable strength, hardness, resonance, and high resistance to chemical attack and thermal shock. This modern upgrade improves upon the white plastic rings used on the original K47, which were prone to discoloring and becoming soaked with impurities over the years, affecting electrical resistance and creating noise. Wunder Audio has optimized passive components by changing capacitor values to achieve a lower corner frequency, resulting in a modern-vintage sound where the spectrum opens up with enhanced sound staging, air, and transparency. The outcome is less grain, more fluid sound, and tighter, sharper focus.
