Cardioid Condenser Microphone

The Sanken CU-55 is a small-diaphragm FET condenser microphone in a compact, side-address form factor. It uses a 16mm capsule with extremely high sensitivity, and includes a pad switch for high-SPL applications.

The mic’s specifications are somewhat remarkable. The stated sensitivity figure of 50.1 mV/Pa puts it among the most sensitive mics we’ve seen. The switchable -10dB pad drops the mic’s effective sensitivity to 15.8mV/Pa, which is comparable to typical studio condensers.

Its self-noise figure of 15dBA is excellent for a small-diaphragm capsule.

CU-55The mic includes a vinyl storage pouch. The pictured shockmount is available as an optional accessory.

The CU-55 was released in 2013, and announced initially at NAB in Las Vegas.
