The XYH6 uses the X/Y miking technique that is optimal for when you want to cover a wide area and still capture sound sources in the center with clarity and definition, making it great for all types of live stereo recording. The supplied XYH-6 X/Y capsule adds two matched high-quality unidirectional microphones to your H6. This kind of microphone is most sensitive to signal coming from directly in front, and less sensitive to signal coming from behind or from the sides; in technical terms, they are said to utilize a cardioid polar pattern. These mics have the largest diaphragm size (0.579" = 14.6mm) of any ever available on a portable recorder.
