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.
