To use a 5.1-channel speaker set, use the surround speakers for the surround channel,
not the surround back channel.
Make sure there are no obstacles between the speakers and the microphone.
If Reverse Phase is displayed, try the following:
— The speaker's wiring (+ and –) may be inverted. Check the speaker connections.
— Depending on the type of speakers and their installation conditions, Reverse Phase
may be displayed even if the speakers are properly connected. If this happens, select
GO NEXT and continue.
— If the speaker is not pointed to the microphone (listening position) or when using
speakers that affect the phase (dipole speakers, reflective speakers, etc.), it may not be
possible to properly identify the polarity.

Place the microphone accurately in the same position as when the Full Auto MCACC

Do not move the speaker used as the reference point. Also, adjust in order, starting from
the front right speaker.
When adjusting the speaker positions, do not move the speakers much; only move them
about 1 cm towards or away from the microphone.
If you forget exactly where the microphone should be positioned or if there are prob-

There are cases where the graph does not appear flat (even when selecting ALL CH ADJ
in the Auto MCACC Setup) due to adjustments made to compensate for room character-
istics to achieve optimal sound.
Areas of the graph may appear identical (before and after) when there is little or no
adjustment needed.
The graph may appear to have shifted vertically when comparing before and after mea-
surements.
Despite level adjustments being made, the filters used for analysis may not display these
adjustments in the reverb characteristics graph after EQ calibration. However, these
adjustments are taken into account by the filters dedicated to overall system calibration.
Low frequencies used in bass management (the subwoofer channel) will not change for
speakers that have been specified as SMALL in the configuration, or do not output these
frequencies.
Calibration is performed, but due to your speakers' low frequency limitations, no measur-
able sound is output for display.
