Thus, if the 2 pairs are mixed together at close to equal gain, there will be a positional 'blurring' of instruments which is unpleasant to the ear....a bit like looking through binoculars with one eyepiece out of focus.

Hence there's been a recommendation to let one pair of mics predominate over the other pair by about 7dB or more, which tends to minimise this divergent image overlay. If the central pair of directional mics are widened from ORTF out to somewhere between 41-47 cams, this image position discrepancy is similarly minimised
