Langevin CR-3A
Common name: Manley Laboratories Langevin CR-3A
Production Status: Discontinued / Vintage
The Langevin CR-3A is a cardioid capacitor microphone suitable for all-purpose use in recording of music, vocals, and speech. Powered by standard 48V phantom power, the all-discrete amplifier circuit employs very low noise transistors and selected FETs. The capsule is a large diameter 1.25″ machined brass ring and back-plate construction. The diaphragm membrane is 6 micron gold over polyester film. Two slide switches on the microphone provide for 10dB pad attenuation and bass roll-off (high pass filter).
