Near Coincidental
Near coincidental or AB mic set up used two matched microphones
set relatively close together, facing in opposite directions. The
spacing between the microphones creates a time delay adding
to the stereo effect. The greater the angle the greater the stereo
spread. Less of an angle yields a more narrow spread. There are
a few standards that specify different angles and spacing, with
the most popular being the ORTF (the acronym given to the
French Broadcasting Organization which stands for Office de
Radiodiffusion Television Française). The ORTF standard specifies
the capsules to be spaced 17cm apart and set at a 110-degree
opposing angle. You can use the C5MP’s included stereo mounting
bar to set the mics in this position. In this setup the stereo image is
created by the differences between level and time. The stereo image
is sharp however it tends not to be mono compatible.
Spaced Pairs
The spaced pair approach uses two identical microphones set rather far apart, for example 2 to 20 feet, or more apart,
both facing directly at the sound source. The further apart that the micro phones are placed, the wider the stereo spread.
