How are stereo microphone setups usually configured for overheads in live sound?

In live sound, stereo microphone setups for overheads commonly employ a spaced pair configuration. This technique involves placing two microphones at a distance apart from each other, capturing sound from a broader area. The goal is to create a sense of space and depth in the audio, which is particularly important in capturing the natural ambiance of a live performance.

The spaced pair method effectively allows for the pickup of sound from different performers and instruments across the stage, as it can help to create a stereo image that feels more immersive. By capturing sounds from various angles, it enhances the overall listening experience by providing a sense of width and separation in the sound stage.

Other methods, such as a close pair or wide pair, do not typically achieve the same level of spatial clarity for overheads in live settings, as they either restrict the sound field too much or do not provide the necessary separation to create a true stereo effect. Random placement of microphones would also be less effective, as it lacks the intentionality and structure that a spaced pair configuration offers, potentially leading to inconsistent audio quality and spatial representation.
