Cardioid Condenser Microphone

The Apex550 is a large-diaphragm FET condenser with a transformerless output. The mic has a large-diaphragm capsule that appears to be a standard K67 type, and a switchable pad (-10dB) and high-pass filter.

The mic ships with its proprietary shockmount, a foam windscreen, and a flightcase.
