During the microphone check, position the

microphones:

as close together as possible
relatively centered between and equidistant from
the front left and right speakers
in a clear line-of-sight path with the speakers
in a location unobstructed by furniture and other
fixtures, where echoes will not obscure calibration
noise signals
at least 2 feet (0.61m) from all speakers and walls,
but within 30 feet (9.14m) of all speakers
The illustration at the right provides an example of proper
microphone placement during the microphone check. All of the
microphones are positioned as close together as possible in an
unobstructed location that is equidistant from the front left and
right speakers.
