The classic AKG C414 microphone has a distinctive timbre designed for high quality recording of solo vocals and solo instruments but also useful for many other applications. With the introduction of the next generation C 414 B-XL models, AKG sets new benchmarks for useful features, improved technical specifications, ease of use and available accessories. These improvements are answers to requests from ever-demanding recording studios, broadcast stations and concert engineers, but with the basic sonic character of the legendary C 414 remains unaltered.
The AKG C414 has high sound pressure level capability and wide dynamic range and is completely immune to electrostatic and electro-magnetic interference from digital gear, computer monitors, etc. thanks to its solid metal housing and transformer-less output stage. It has 3 switchable bass cut filters and 3 pre-attenuation pads with LEDs for quick visual indication and all switchable components operate in low impedance circuits for ultra-high reliability even in extremely humid conditions.
Having high sensitivity and extremely low self noise, 5 switchable polar patterns for placement and application flexibility plus 2-color LEDs provide quick visual indication of selected polar pattern and output overload makes this version an excellent choice.
The supplied elastic capsule suspension greatly minimizes structurally-transmitted noise from chassis vibration (H 85 professional shock mount/stand adapter) and the kit comes supplied with PF 80 external pop filter and W 414 X external windscreen. An optional R 414 remote control unit offers full control of all switchable parameters via standard microphone cable and 3-pin XLR-type connector.
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. 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.
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. 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.
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 C (-13 F) and +65 C (+149 F) as well as relative humidity as high as 99% (immediately below point of condensation) above +20 C (+68 F). The new C 414 B models can handle temperature extremes anywhere and still deliver perfect performance.
