POSITIONING THE MICROPHONES FOR THE MICROPHONE CHECK
Refer to the microphone placement examples that begin below to position the microphones for the microphone check.
During the microphone check, position
the microphones:
3 As close together as possible
3 Relatively centered between and equidistant from
the front left and right speakers
3 In a clear line-of-sight path with the speakers
3 In a location unobstructed by furniture and other
fixtures, where echoes will not obscure calibration
noise signals
3 At least 2 feet (0.61m) from all speakers and
walls, but within 30 feet (9.14m) of all speakers
The illustration to 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.
