Near Coincidental; Spaced Pairs - Miktek CV3MP Owner's Manual

Stereo Miking Techniques

Near Coincidental

Near coincidental or AB mic set up use 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 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
microphones are placed, the wider the stereo spread
