The solid metal housing and transformer-less output stage combine to make the C 414 B-XL microphones immune to electrical interference from digital equipment, video monitors or from rf from wireless microphone or other communications systems.
5 Polar Patterns
The twin-diaphragm system gives you a choice of five different polar patterns (omnidirectional, wide cardioid, cardioid, hypercardioid, and figure eight). The diaphragm is made from a special gold-sputtered plastic foil and the gold layer is deposited on the diaphragm only on the outer sides to prevent short circuiting to the back plate if strong blasts of air are applied.
Elastic Capsule Suspension
Structurally transmitted vibrations that interfere and color the sound are almost completely eliminated thanks to a new elastic capsule suspension system.
3 Switchable Pre-Attenuation Levels
Pre-attenuation levels are controlled by changes in the polarization voltage of the capsule and permit increases of 6, 12 or 18 dB in the maximum sound pressure level for close-up recording or for use on high-output sources.
3 switchable Bass Filters
The switchable bass-cut filters reduce sonic coloration and the risk of low frequency distortion. The slope of the 40 and 80 Hz filters is more than 12 dB-per-octave and these are especially useful in combating wind noise or vibrations from stage floors. The 160 Hz filter has a gentler 6 dB-per-octave slope useful in minimizing proximity effect.
Predictable Performance Even in Humid Conditions
To minimize the negative effects of humidity, all switching circuits are located in a sealed low-impedance section to prevent problems. To test the stability of our microphones’ performance, they are tested in simulated climatic conditions between -25 degrees Celsius (-13 degrees Farenheit) and +65 degrees Celsius (+149 degrees Farenheit) as well as relative humidity as high as 99% (immediately below point of condensation) above +20 degrees Celsius (+68 degrees Farenheit). The new C 414 B models can handle temperature extremes anywhere and still deliver perfect performance.
AKG Acoustics (originally Akustische und Kino-Geräte Gesellschaft m.b.H., English: Acoustic and Cinema Equipment L.L.C.) is an acoustics engineering and manufacturing company. It was founded in 1947 by Dr. Rudolf Görike and Ernest Plass in Vienna, Austria. It is a part of Harman International Industries, a subsidiary of Samsung Electronics.
The products currently marketed under the AKG brand mostly consist of microphones, headphones, wireless audio systems and related accessories for professional and consumer markets.
