Wunder Audio CM7 FET
Cardioid Condenser Microphone
The CM7 Fet is a modern homage to Neumann’s famous U47 Fet. Both are transformer-coupled solid-state mics with a K47/K49-style large-diaphragm capsule.
Wunder’s K47 capsule, like the original, is a single-backplate, center-terminated, dual-diaphragm design.
The mic’s amplifier circuit is not a strict recreation of the Neumann design; rather, it has been updated with modern components.
Mike Castoro, 2010
[The CM7 Fet] has a more modern FET… The original was designed when solid-state was very new, so we took advantages of newer FET technology.
The output transformer is custom wound in the US, specifically for this microphone.
The mic’s body shape and size, and the dimensions and construction of the grille, are identical to the U47Fet.
Brad Avenson of Avenson Audio participated in the design of this microphone.
The Wunder Audio CM7 FET is also known as: CM-7 FET.
The mic was released in 2009.
