This is an excellent condition Advanced Audio CM-47 Microphone that has never left my smoke-free, pet-free home studio. It is a pro quality large diaphragm microphone, which was only enhanced when a new-old-stock (NOS) RCA 12AY7 was installed in the microphone. You can get that spot-on smooth, warm but clear, velvety vocals that made the U47 a studio standard. The mic ships in a road case with power supply, cable, and shock-mount.The Advanced Audio CM47 is a large dual-diaphragm. Multi-pattern, tube condenser microphone inspired by the famous Neumann U-47. The CM47 is a great choice for vocals, saxophones, acoustic instruments, and. Excels in front of bass and guitar amps. The Advanced Audio CM47 features our very accurate and smooth AK67 capsule, a 35mm capsule with 6-micron-thick German mylar diaphragms. Its frequency response falls between those of the U47 and U67 vintage tube microphones.
The AK67 capsule goes down another ½ octave before rolling out, compared to the K47 capsule. The CM47 also has moreair or sizzle above 10kHz, allowing it to cut more easily through busy mixes without adding EQ. The circuit is based on the very hifi 6072 tube optimized with a two-stage Class A design. This circuit provides a much lower output impedance withmore headroom than the circuit used in the original U47. The lower outputimpedance provides a faster damping factor when driving the BV8 typetransformer, delivering a better transient response than the original design.
The dual-bobbin output transformer with its hum buckingconfiguration and our optimized circuit will deliver +20dBu with less than 1%distortion. The output transformer is driven with a 2.2 ufd metal-filmcapacitor to take advantage of the transformers response down to 10Hz. Advanced Audio also modifies the amplifier circuit to provide more headroom than in the original U-47, with better transient response, by implementing a cathode-follower design. The transformer is a Chinese-manufactured copy of the Neumann BV8.
Like the U-47/U-48, the CM-47 is a multipattern microphone. Whereas the U47/U48 offered only two patterns, the CM-47 can be switched among 9 selectable patterns, via a rotary switch on the remote power supply.
