How do I set up my microphones for a stereo recording ? 90 Degree X-Y configurations This is the most common form of stereo recording, the 90 degree X-Y configuration. Here careful attention should be paid to the vertical alignment of the diaphram inside the capsule. The smaller the error the better the focus and depth of the recording. The horizontal displacement is not critical and can be adjusted to accomadate larger microphones or the use of windscreens. This works well with both cardiod and hypercardiod microphones. This is our recommended starting point for all new recording engineers. We find that all large diaphram microphones must be set up in this manner to assure satisfing results.
