The Advanced Audio CM414 Microphone is a large dual-diaphragm, 3-pattern fet microphone based on the early AKG C414eb.
The CM414 response is very smooth up to 8kHz, then rises to about 4dB at 15kHz, adding an “airy” quality to the sound. The CM414 has a more present sound than the later AKG C414/P48.
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 1.5 dB, the response of the capsules used in the AKG C12 and early C414eb microphones. This is the same capsule used in our popular CM12se tube microphone.
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 then coupled into the output transformer, a strategy superior to the single-fet method used in the Neumann U87. This increases the overall headroom by 14db making it ideal for capturing drum, percussion & grand piano. The CM414 has a -10dB pad, a low-frequency roll-off switch, and 3-way pattern switch on the body.
