to achieve the best results for multiple listening positions in multiple rows
When calibrating for a multiple listening
positions in multiple rows, place the
microphones:
✓ at the approximate spot where the listener’s head
will be during listening
✓ 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 when calibrating for multiple listening
positions in multiple rows. Each microphone is positioned in a
single listening position within the rows, allowing the MC-12 to
calibrate optimal speaker distances and output levels for a larger
listening area at the expense of a single listening position.
