Large Diaphragm Condenser Microphone
Description
The AKG model C414B/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 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 C414B/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.
Features
• One of the world's most celebrated
stereo condenser microphones

diaphragm format optimized for
studio applications
• Dual diaphragm for multiple
polar patterns
• High acoustic level capability
(140 dB-SPL for 0.5% THD)
• Low self noise (14 dB-A)

AKG is constantly improving and modifying it’s products, therefore, specifications are subject to change without notice.
The microphone shall provide at least four switchable pickup
patterns that are nominally omnidirectional, cardioid,
hypercardioid, and figure-eight. The microphone shall have
maximum sensitivity along its radius, and that sensitivity shall be
no less than 12.5 mV/Pa for all patterns. The microphone shall
provide a switchable 12 dB/octave rolloff at frequencies of 75
and 150 Hz. Pre-preamp attenuation switches of -10 and -20 dB
shall also be provided, and the self noise floor of the microphone
in its unpadded operation shall be no greater than 14 dB
(A weighted). The unpadded microphone shall operate in a wide-
band sound field of 140 dB-SPL with no more than 0.5 % total
harmonic distortion. The microphone case shall fit within a
rectangular envelope no larger than 141 x 45 x 35 mm. The
microphone shall be the AKG model 414B/ULS.
