The Advanced Audio CM47ve is a large dual-diaphragm, multi-pattern, tube condenser microphone inspired by the famous Neumann U-47. The CM47ve is a great choice for vocals, horns, acoustic instruments, and excels in front of bass and guitar amps. The CM47ve provides response within ±1.5 dB of a U47 microphone made after 1958.
The Advanced Audio CM47ve features Advanced's AK47 capsule. The AK47 is an exact reproduction of the early Neumann K47. The AK47 is a 32mm capsule with single back-plate, random drill pattern and is skinned with 6 micron mylar and a brass surround like the 1959 k47. The CM47ve yields a more vintage, 'darker' response curve than the CM47 above 10 kHz but has a very present sound with a slightly wider proximity effect than the CM47.
The circuit is based on the very hi-fi 6072 tube optimized with a state of the art two-stage Class A CCDA design. This circuit provides a much lower output impedance with more headroom than the circuit used in the original U47. The lower output impedance provides a faster damping factor when driving the BV8 type transformer, delivering a better transient response than the original design. Selected 6072a tubes are some of the quietest tubes made, and are much less susceptible to microphonics than the metal-clad vf14 tubes used in the original U47 tube microphone.
The dual-bobbin output transformer with its humbucking configuration and our optimized circuit will deliver >+14 dBu with less than 1% distortion. The output transformer is driven with a 2.2 ufd metal-film capacitor to take advantage of the transformer’s response down below 20 Hz.
