Advanced Audio CM47fet/CE FET Condenser Microphone

Large diaphragm FET condenser microphone with an AK47 capsule based on the extended headroom of the famous Neumann U47fet design
MFR# CM47fet/CE

Product Description

The Advanced Audio CM47fet/CE came about in response to requests to retrofit the CM47fet with the AK47 capsule, to give it the more traditional, vintage sound of the U47fet but with the added omni feature.

The Advanced Audio Custom Edition CM47fet provides a sonic response similar to the original U47fet. It has a smooth presence but sounds slightly warmer or "darker" than the CM47fet. It has become a favorite in front of the kick drum, on upright bass, trumpet, trombone, in front of guitar and bass amps where a warm but present sound is required.

The CM47fet circuit is based on the extended headroom of the famous Neumann U47fet design. It features the AK47 capsule which is a true reproduction of the original K47 capsule made in the late 50s. The two-stage Class A amplifier is coupled into a transformer balanced output. It also features a de-emphasis circuit that reduces sibilance but gives it the presence of a U47/U47fet with incredible smoothness. The CM47fet/CE has been optimized for close miking applications on loud sound sources so that it will not overload even economic transformerless preamplifiers. The CM47fet/CE also features passive true cardioid operation like the original U47/U48 and U47fet microphones. It can also be switched to omni operation for room miking duties or when the need to reduce any proximity effect is required.

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!

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.
Phil T.
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.
