Advanced Audio Microphones CM-47
MSRP: $735 Multi-Pattern Condenser Tube Microphone
Description
The CM-47 is a tube mic built in China, then upgraded with a Peluso CEK-367 capsule — a Neumann U47-style, 34mm dual diaphragm capsule built with imported German 6-micron Mylar.
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 stock transformer is traded for a “BV8 dual bobbin output transformer wound to the original Telefunken blueprints,” most likely a Cinemag unit. (Hear a comparison of the Neumann BV8 to a Cinemag CM-2461 NiCo FFT.)
Like the U-47/U-48, the CM-47 is a multipattern microphone, offering 9 selectable patterns via switch on the remote power supply.
The mic ships in a road case with power supply, cable, and shockmount.
The Advanced Audio Microphones CM-47 is also known as: CM47.
The mic was released in 2007.
