POSITIONING THE MICROPHONES FOR AUTOMATIC CALIBRATION (continued)
When calibrating for a single listening
position, place the microphones:
3 As close together as possible in a single listening
position (the primary listening position)
3 At the approximate spot where the listener’s
head will be during listening
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 when calibrating for a
single listening position. The microphones are
positioned as close together as possible in a single
listening position, allowing the MC-12 to calibrate
optimal speaker distances and output levels for that
position.
