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 program. Using this matched pair for stereo recordings in various techniques will provide a good and stable balance without frequency-dependent shifting of the stereo panorama. The kit includes all the standard accessories of the deluxe package (excluding the PF 80) along with a stereo bar and proof of performance charts in an attractive carrying case (large Soundtool case).
