The H6 Handy allows for versatile recording techniques, giving you several options right out of the box. The included XYH-6 XY microphone module is made up of two matched unidirectional condenser microphones and is intended for capturing accurate, phase-correct stereo audio. The module allows you to adjust the angle of the two mics to either 90 degrees, or for a wider stereo image, 120 degrees.For situations that call for audio that allows for width control over your stereo image after it has been recorded, the XY module can be switched out for the MSH-6 mid-side stereo microphone module. Contrary to the appearance of the capsule, the mid-side module actually contains two elements positioned on top of one another: a unidirectional mic which faces forward (mid), and a bi-directional mic set perpendicular to it (side). In addition to providing you the ability to adjust the width of your stereo audio after it has been recorded, MS recording also provides true mono compatibility, a factor that comes into play in situations such as television production.
