AKG C414 XL II ST Stereo Set Condenser Microphones The C414 XLII multi-pattern condenser microphone offers a choice of nine polar patterns for the perfect sonic capture for every application. A peak hold LED displays even the shortest overload peaks. For live sound applications and permanent installations, all controls can easily be disabled for trouble-free use. The C414 XLII version differs from the C414 XLS version in one major respect – the capsule. The C414 XLII's slight presence boost and impressive spatial reproduction are both similar to the legendary AKG C12 microphone from 1953. Realistic stereo recordings require microphones with outstanding performance and excellent quality. They also require performance consistency and accurate localisation from the pair of microphones. Therefore, every factory-matched pair has been created from thousands of individual microphones selected by AKG's sophisticated computer-aided matching method. The result is the highest possible correlation over the whole frequency range and virtually identical sensitivity for stunning, three-dimensional recordings. The matched pairs consist of two microphones that are within 1 dB to each other in sensitivity and also within 1 dB to each other in the range of 300 Hz to 8,000 Hz of the individual frequency response when used in cardioid mode. The microphones are selected from a large quantity of individual microphones according to the described criteria by using a proprietary computer pr
