Advanced Audio CM47ve Tube Condenser Microphone

Large dual-diaphragm, multi-pattern, tube condenser microphone inspired by the famous Neumann U-47 great choice for vocals, horns, acoustic instruments, and more

Product Description

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.


  • 1” (32mm) AK47 single back plate, 6-micron skinned mylar capsule
  • Capsule polarization 60V on the back-plate

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
