Advanced Audio CM67se
Our CM67 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.
Capsule
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.
Circuit
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 BV8 output transformer, which is wound to the original Neumann specs. The BV8 will deliver +18dBm with less than 1% distortion and with a flat response down to 20Hz.
