Description
The AKG Model C 414 B/ULS is certainly the most
ubiquitous studio condenser microphone in the United States,
and very likely in the rest of the world as well. It is designed
around dual back-to-back large 1 in. (25 mm) gold sputtered
diaphragms for multiple pickup patterns. The microphone's
pickup patterns are easily switchable among omnidirectional,
cardioid, hypercardioid, and figure-eight. Additional flexibility
in the studio operating environment allows a bass cut of
12 dB/octave below 150 or 75 Hz and pre-preamp attenuation
of either 10 or 20 dB. The self noise of the microphone is a
low 14 dB (A weighted). On-axis sensitivity for all patterns is
12.5 mV/Pa, and for unpadded operation maximum program
level is 140 dB for 0.5% total harmonic distortion.
The C 414 B/ULS is one of the most accurate multi-pattern
microphones available to the engineer. The far-field on-axis
response for all four switchable patterns is remarkably flat,
varying no more than +/-2 dB over the range from 20 to 20 kHz.
