Advanced Audio CM67se Tube Condenser Microphone

The Advanced Audio CM67se is a large dual-diaphragm tube condenser microphone inspired by the famous Neumann U67 design and specifications. The CM67 has an ultra-smooth natural rise above 10 kHz and is a favorite for group vocals and singers who want a very detailed sound. It is also a favorite microphone for recording acoustic instruments.

Advanced Audio’s AK67 capsule is a very accurate 35mm capsule with 6-micron German mylar diaphragms. Its frequency response matches within 2 dB the response of the Neumann K47 capsule used in Neumann’s K67 tube and U87 microphones.

The CM67 features an upgraded 6072a circuit that provides a lower output impedance with slightly more headroom than the circuit used in the original U67. In addition, it provides a faster transient response when driving the very HiFi output transformer, which is wound to the original Neumann specs. The transformer will deliver +14 dBu with less than 0.5% distortion and with a flat response down to 20 Hz.
