RECOMMENDED microphone positioning for the microphone check

During the microphone check, do not:

separate the microphones
scatter the microphones throughout the listening
space
obstruct the line-of-sight path between the
microphones and the speakers
position the microphones on the floor, on seat
cushions, or in locations obstructed by furniture
and other fixtures, where echoes might obscure
calibration noise signals
position the microphones within 2 feet (0.61m) of
speakers and walls or more than 30 feet (9.14m)
from any one speaker
The illustration at the right provides an example of improper
microphone placement during the microphone check. The
microphones are scattered throughout the listening space rather
than positioned as close together as possible in a location that is
equidistant from the front left and right speakers. In addition,
two microphones are positioned on the floor and two
microphones are positioned on a table obstructed by furniture.
