Cascade Microphones M20u
Cardioid Condenser Microphone
The M20u is a large-diaphragm, fixed-cardioid condenser microphone.
The capsule is a single-membrane, externally biased (true condenser). Although previously reported here as a 5-micron edge-terminated model, we believe it is a 6-micron 32mm center-terminated K67 design.
Onboard switches provide access to a high-pass filter (-6dB/octave @ 100Hz) and a preattenuation pad (-10dB).
The M20u’s transformer coupled output stage provides the primary difference from Cascade’s similar V57 mic, which employs the same capsule, similar circuitry, and a transformerless output.
It ships with a soft pouch, suspension shockmount, and an aluminum flight case.
Cascade’s earlier M20 microphone was initially provided as a giveaway item by Bayview Pro Audio (parent company to Cascade Microphones); it was received as a garden-variety Chinese LDC — useful, but not special. It closely resembled the ADK A51 of that time. (Both ADK and Cascade have changed manufacturers since then.)
The Cascade Microphones M20u is also known as: M20.
The mic was released in 2006.
