Josephson Engineering C550
The Josephson Engineering C550 series is a "half inch" model available in three sensitivity steps, each one covering an operating range of about 100 dB.
The C550H provides 10 mV/Pa output, suitable for microphone level inputs. The L version is more sensitive, for use with line level inputs, while the F version has lower sensitivity for use in high sound pressure level measurements. Frequency response is flat for on-axis sound incidence, but any of the models may also be supplied with a -D suffix for flat diffuse field response. All models may be powered with 24 to 48 volt phantom supplies, and provide symmetrical active balanced outputs. They will also operate on phantom power as low as 15V with some reduction in maximum level.
