How do I set up my microphones for a stereo recording ? Outdoor Configurations These images show the basics for setting up a pair of cardiod (which should be 110-120 degrees) or sub-cardiod (which should be 120-130 degrees) microphones for outdoor use. Very few indoor venues would allow for this kind of wide pickup. The two bottom images demonstrate the vertical spacing needed to accomadate windsceens (please note pop screens are NOT suited to outdoor recording). Using this wide pickup provides a more natural sense of space and better bass response.
