Advanced Audio CM414

The CM414 is a large dual-diaphragm, 3-pattern fet microphone based on the design and specifications of AKG’s famous C414. The CM414 response is very smooth up to 8kHz, then rises to about 4dB at 15kHz, adding an “airy” quality to the sound.     

Capsule

The Advanced Audio CM414 features a 34mm capsule with 6-micron-thick German mylar diaphragms. This capsule is very accurate and has a smooth frequency response that matches within 2 dB the response of the capsules used in the AKCG C12 and early C414 microphones. It is the same capsule used in our popular CM12.

Circuit

The CM414 uses a two-stage Class A fet circuit similar to the one found in the original C414. The fet is buffered by a discrete transistor before being coupled into the output transformer, a strategy superior to the single-fet method used in the Neumann U87.

The CM414 has a -10dB pad, a low-frequency roll-off switch, and 3-way pattern switch on the body.
