Wunder Audio CM50 FET S

The Wunder Audio CM50 condenser microphone is ideal for capturing huge drum sounds and captures great room noise by giving the instruments volume and depth making this microphone a great choice for orchestral recordings.

The grille features a slant found in other Wunder microphones to help reduce the resonance and standing waves providing a great natural sound. The Wunder Audio CM50FET S is nestled in a beautiful foam-lined, velvet, oak-wooden box to protect the microphone.

The CM50 FET S has a slanted grille to limit the effect of grille resonance on the response. Because the grille is slanted and presents a continuously varying profile to the capsule, there are fewer standing waves generated. This gives the most natural sound obtainable by any microphone. Very pure and pleasantly warm. The size of the grille forms a larger-volume enclosure giving the capsule more breathing room and contributing to its openness. In every way the Wunder Audio CM50 FET Suprema grille is true to vintage and identical to the original M50. It has been used as historical replacement parts on the vintage M50s.

Fet circuitry
Wunder Audio CM50 FET Suprema incorporates an audiophile grade MOSFET circuit. Sonically, the MOSFETs enhance low-level detail retrieval and provide a startling improvement in low noise performance, adding a sense of purity on vocals and strings thought to be impossible in transistor amplification. There is also a sense of linearity that allows the microphone to maintain consistency of clarity and tonal balance from low to high levels, so there is no more confusion and congestion when the volume is pushed. The staging, depth retrieval and the overall presentation takes on just the right balance of airiness and bloom.

The CM50 Suprema uses the same M9 capsule as the historic M50. Neumann went through several materials for their diaphragm, starting with PVC which quickly became too brittle, then went to aluminum which was difficult to tension correctly. For a brief period nickel was used and finally the decision was to use Mylar, as in the KM 83. Wunder have successfully recreated the small pressure transducer, similar to the capsule for the KM series microphones, embedded in the surface of a 40 mm diameter Lucite sphere. By mounting the miniature capsule in the large Lucite sphere all standing waves larger than 40 mm are eliminated thus canceling out proximity effect. No other microphone set to Omni can achieve the naturalness of the CM50 S sound. The inspiration is classic, the execution is cutting-edge.

Box and yoke mount
Your Wunder Audio CM50FET S is nestled in velvet and softly secured in place in a foam-lined oak-wooden box that is clasped and hinged. This beautiful oak box is also sold separately. Your CM50 S yoke mount is an improved one-piece design for durability.
