The 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 10khz 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 our the very HiFi output transformer, which is wound to the original Neumann specs. The transformer will deliver +14dBu with less than .5% distortion and with a flat response down to 20Hz.



  • AK67 1.07"/35mm capsule with 6-micron diaphragms
  • 9 pick-up patterns selectable from the power supply
  • Class A 6072a 2-stage tube circuit
  • Dual bobbin output transformer with Bi-metal laminations (6.5:1 ratio)
  • -10db pad switched from the front of microphone body
  • 80HZ HP filter switched from the from to microphone body
  • Frequency response: 20Hz to 20kHz ±3db
  • Noise: <14dB(A-weighted)
  • Maximum output level > +14dbu.
  • Impedance: <200 ohm(load impedance <1.2K)
  • Distortion: 0.5% @ 126dB and 136db with pad engaged
  • Robust shock-mount
  • Aluminum road case
