numerical value of the distance, actually move the
physical positions of the speakers to fine-adjust (the
subwoofer cannot be adjusted). The input from the
microphone is indicated on the screen. Fine-adjust the
positions of the speakers so that the gauge reading is
maximum. The detailed distance adjustments that were
previously performed by skilled installers by ear can
easily be performed watching the gauge on the monitor.
Place the microphone in the same position as when the
microphone was connected and the Full Auto MCACC
operation was performed.

Select ‘Precision Distance’ from the Manual
MCACC setup menu.

inch towards or away from the
microphone. Watch the screen when doing so, and fine-
adjust the positions of the speakers so that the gauge
reading is maximum. Also, the channel serving as the
standard differs according to the channel being
adjusted. Do not move the speaker serving as the
standard channel.
The maximum gauge reading is 10.0. (If the reading stays
under 10.0, adjust the speaker for the maximum value.)

on page 112, you can check your calibrated settings
using the GUI screen or, if a computer is connected, on
the computer’s screen.

Note
1 • If the microphone is placed in a different position from when the Auto MCACC procedure was performed, it may not be possible to adjust properly. In
this case, we recommend performing the procedure at
Fine Speaker Distance
on page 114 in the Auto MCACC custom measurements, then performing the
adjustment described here without moving the microphone.
• The adjustment here is for adjusting for an error of 1/2 inch or less (not adjustable with the Auto MCACC Setup). 0.0 may be displayed after distance
correction with the Auto MCACC Setup, but even in this case this adjustment allows you to optimize the correction. Note that if the Auto MCACC Setup is
performed after completing the fine-adjustment here, the correction precision will drop to about 1/2 inch.
• Like with the Auto MCACC Setup, perform this adjustment in as quiet an environment as possible. 0.0 will be displayed if abrupt noise is input during the
adjustment.
• The distance for all the channels can only be made uniform even if the
R
(front right) channel is adjusted in the proper order.
• Be very careful not to tip the speakers over when moving them.
• The result of the adjustment performed here can be checked by listening to the test pulses output at the
Precision Distance (SC-27 only)
on page 117 (the
test pulses will be more centrally positioned between the speakers than before the adjustment was performed). Be careful not to change the distance values
at this time.
